The scope of the invention

The present invention relates to a reinforcement device for reinforcing the toe at the Foundation pile Foundation using the Foundation piles, which has at least one end-to-end longitudinal cavity and the base of which is reinforced by means of reinforcing device having at least one end-to-end longitudinal cavity.

The invention also relates to a method for installation of Foundation piles and reinforcement of its base by means of a reinforcing device.

The level of technology

When the Foundation of a large building structures such as houses, walls, towers and the like, typically use Foundation, supported by several Foundation piles installed in the ground to support the Foundation, as well as for depreciation tensile and compressive efforts, which occurs under the influence of its own weight and wind load.

For absorbing compressive forces are usually applied smooth Foundation piling, who hammered into the ground until it stops in a solid layer of rock. Thus, when using this method, in some cases, you have to hammer into the ground many meters of piles before her bottom will reach solid ground. Therefore, this method of laying the Foundation can be quite doregos oasis.

During the construction of foundations in areas where the soil research has shown that a solid Foundation is deep, use a different type of Foundation piles, on the lower end of which has a sole of a diameter greater than the diameter of the piles. In this case, the pressure exerted on the pile, is distributed over a larger area, and the sole makes a draft of the piles in the soil under the pressure of its own weight.

Since the Foundation pile with an extended sole impossible to score, or enter under pressure in a drilled well, we have found various ways to first install the pile, and then to form an enlarged reinforcing device.

In U.S. patent No. 3832859 described a similar pile with a reinforcing device, which is designed in such a way that when driving into the ground it can be embedded in the soil a few supports, after which the base of the pile is poured to form the sole, the size of which exceeds the diameter of the Foundation piles.

The disadvantage is described in U.S. patent No. 3832859 smooth piles and piles with extended relative to the outer perimeter of the piles sole is that these piles do not provide depreciation tensile forces.

This tensile stress occurs, for example, in the case where part of a building or tower feel the effects of the influence of wind loads; when this pile Foundation on the leeward side are under compressive stress, while in piles on the windward side effect of tensile force.

For piles that are able to absorb the tensile stress, the advantage is that the length of the pile at least one of the tide and/or soles, the diameter of which is, or which at least in one location in excess of the diameter of the piles. Due to the increased diameter of the specified tide or the soles of the pile can absorb a greater tensile stress than the smooth pile, as the tide or the sole affected by the mass of soil distributed in the form of an upward cone above tide or sole.

When using smooth pile tensile stress is depreciated only by the suction action of the soil, which is manifested in the fact that when pulling piles from your place in the hole protruding from the pile under the action of force of resistance between the surrounding soil and the surface of the pile occurs abnormally low pressure.

There are various ways to create a pile that is in the earth, tide or soles. One of them is that through the longitudinal through channel available in the pile, is injected under pressure cured filler entering the soil through the bottom frequent the piles or through cross-priming channels, located along the length of the piles.

Such tides or soles usually are reinforced by means of reinforcing devices to ensure that they can withstand the increased tensile force. In U.S. patent No. 3832859 described reinforcing device is designed in such a way that when introduced under pressure into the well it releases into the soil supports, which are then poured to form the sole of a diameter greater than the diameter of the piles.

The disadvantage of using this reinforcing device of the toe is that in this case the valve is located on top of the reinforcing device, that is, reinforcement is not widely distributed across the sole, and, therefore, is only a small increase in resistance to stretching. For optimum resistance soles reinforcement details of reinforcement devices must be distributed over the largest possible area of the sole.

Pile described in U.S. patent No. 3832859, will have a specific resistance, tensile strength, but, in particular, in clay soil, it will be due to design features. Thus, it may happen branch piles from a molded soles and supports deployed in the ground, because of the design of the reinforcing device will not hold when pulling piles up, so that the reinforcing device is on will be. Therefore, this design has the same resistance to stretching and smooth Foundation pile.

Aspects of the invention

Thus, the aim of the present invention is to provide such a reinforcement device that is easily installed in the base of the pile and which is simple and reliable way provides uniform distribution of reinforcement in the sole.

This can be achieved by the application of a reinforcing device like described above, the feature of which is that the device includes several curly articulated reinforcing parts, pivotally connected to and located on the centre of the ring element, so that the reinforcing device may be in a folded state, in which it is located when installed, and in a deployed state in which it is in operation, thus reinforcing device is connected to the pile at least one element, working in tension.

In addition, the present invention is the creation of piles, is able to absorb these compressive and tensile forces, simple and inexpensive in manufacture and installation in the specified position.

This can be achieved through the use of piles having a reinforcing device associated with it by means of at least one element is a, working on stretching.

A further purpose of the invention is to provide a simple and inexpensive method of installation of Foundation piles and more reliable way of reinforcing its base by means of a reinforcing device.

These goals are achieved through the creation of a method, in which the placement and reinforcement of piles include:

installation of piles in a predetermined position under pressure by ramming or by dropping in a pre-drilled hole

- opening under the pressure of the folded reinforcing device through at least one end-to-end longitudinal cavity of the pile,

- upon reaching the reinforcing device of the lower end of the pile moving it under pressure for some distance down; driven means expanding the reinforcement details of the reinforcing device with education thus network consisting of at least reinforcing parts of a reinforcing device, and

- supply under pressure through the specified at least one end-to-end longitudinal cavity piles cured filler, so that the lower part of the pile and the expanded reinforcing device are sealed in a single casting for the formation of the reinforced soles, the dimensions of which exceed the dimensions of the Foundation piles.

The invention

Below is described the pile with p is Dosbol, reinforced by means of reinforcing device, which is used in the foundations of wind turbines, as well as the installation method of this Foundation piles and reinforcing her soles. In addition, the proposed invention the combined elements can also be used when laying the foundations of other types of towers, such as flue or exhaust pipe, high flagpoles, columns, beams, transmission lines, and antennas. Moreover, piles can be used in the Foundation of houses, bridges, floating grounds and similar building structures.

Reinforcing device includes a sliding mechanism that allows to lower the pressure reinforcing device through a through axial cavity of piles and can make the filling valves of the largest available space soles or its distribution on the largest available space soles. Thus, the reinforcing device when it is installed under the lower end of the pile is made with the possibility of expanding with the formation of the reinforcing network that can be filled with education soles.

The sliding mechanism is a multiple articulated reinforcing parts, pivotally connected to and located on the centre of the ring element, so that the reinforcing device may be folded, in kotroman is when installing, and in a deployed state in which it is in operation. Therefore, after the production of the reinforcing device can be placed in end-to-end longitudinal cavity piles, for example during transport, and again to remove when installing piles in the ground.

Due to the fact that the articulated reinforcement details pivotally connected with located in the center of the ring element, the reinforcement details of the reinforcing device will serve as guides, interacting with the inner side through the longitudinal cavity of the pile when lowering the reinforcing device down under pressure in the folded state of the installation.

To transfer tensile forces from the sole to the Foundation in reinforcing device there are several elements working in tension, which originate from the reinforcing device and held to the base, whereby the reinforcing device is connected with the Foundation pile.

To transfer tensile forces from the tower to a reinforcing device for the sole use of the elements working in tension, one end attached to the base and at the other end to a reinforcing device. As such elements working in tension, can serve cables, threaded rods and/or round steel rod with threaded end or other means of fixation. the selecting element, working on stretching depends on the type of Foundation, the length of the piles and soil conditions.

In one embodiment, a reinforcing device includes a series of pipes through each of which passes a unit that operates in tension attached to the lower end of the pipe, and at least one reinforcement element of the fastening device. Each element working in tension, passes through the pipe down and fastened to the reinforcement details. Pipes can also be attached to at least one reinforcing details.

The data length of pipe or corresponds to the height of spaced reinforcing device or exceeds this height. Therefore, these elements working in tension, such as cables, protected from tangling, which can cause stress concentration, which decreases the strength of the ropes, and in the worst case they break. In addition, prevented tangling cables in the reinforcement details.

To limit the distance that diverge reinforcing parts, each pipe is connected with at least one reinforcing part. Thus, extracting the reinforcing parts out occurs relative to the center of the Foundation piles and evenly distributed on the number of pipes, which are equipped with arm is the dominant device.

Under the influence of compressive efforts pile can hit under her soles and destroy it. To prevent this, the reinforcing device is further provided with multiple jammers that are attached to the upper end of the at least one pipe and have the same cross-sectional shape, which ensures the existence of at least one retaining surface.

The stoppers are made with such cross-sectional shape, which ensures the existence of at least one retaining surface. In one embodiment, the invention is used the cut out detail, preferably in the form of an annular area with a vertical part and an approximately horizontal part. The vertical part is connected with at least one pipe, and the horizontal part is retaining surface. During the descent, under the pressure of the folded reinforcing device reinforcing details can form the gap between the pipe reinforcing device and the inner side of the through longitudinal cavity of the pile.

The retaining surface is used when the reinforcing device is lowered below the lower end of the Foundation piles and deployed, while the vertical portion adjacent to the inner side through the longitudinal cavity of the pile and the horizontal part is located below the bottom edge of the pile and thus the om serves as a stopper, opposing tensile force in the elements working in tension.

The cross-section of the stopper usually has a G-shaped, but may also be U-shaped or C-shaped, or flat. However, the presence of a gap between the ends of the vertical parts, so that the lower edge of the Foundation piles is always to enter in the stopper and rests against the retaining surface.

In one embodiment, the stoppers attached to the upper ends of pipes and together with the reinforcement parts can function as guides, and to hold the pipe in place during lowering of the reinforcing device under pressure through the longitudinal cavity of the pile.

In order to regulate and direct reinforcement details at the time of their nomination in one embodiment, a connection between the pipe and the reinforcement details in reinforcing device fully or partly represent the hinges. This design helps to ensure the connection of reinforcing steel elements with pipes, and thus allows the reinforcing elements can freely slide in the hinge connections and to be extended outwardly relative to the center of the Foundation piles.

Each pipe you can install more than one hinge, so that the pipe will be connected, for example, with two reinforcing detail is Yami. This means that the reinforcement details in reinforcing device may be larger than the pipe that provides the best reinforcement of the sole.

To transfer tensile forces flooded reinforcing device on the Foundation elements working in tension originating from the reinforcing device and continuing to Foundation must be connected at least with one part of the reinforcing device using at least one of the following tools: threaded connections, clamping connections and/or welding.

In one embodiment, as part of working in tension, use the cable that is attached to the lower end of the pipe and the reinforcing parts by means of a threaded connection located under the valve parts. This threaded connection may be self-locking so that when the rope tension disconnecting cables from the reinforcing device is prevented.

In the second embodiment, as part of working in tension, use the cable that is attached to the lower end of the pipe and reinforcing details using a clamping connection, usually made in the form of cable clamp located below the reinforcement details. These clamps back bottom reinforcement details and thus prevent the indicate the weakening of the cables when the tension.

In the third embodiment, the elements working in tension, such as cable, threaded rod or round steel rod, welded from the bottom to the reinforcement details. Welding must be done in such a way that the elements working in tension, not undermined when welding under the action of heat.

To the lower edge of the piles under the influence of compressive efforts did not hit underneath the sole and not destroy it, reinforcing device may be additionally provided with several blocks that are attached to the foldable construction element, working in tension, and have such cross-sectional shape, which ensures the existence of at least one retaining surface.

The elements working in tension, is divided into an upper part that extends from the Foundation down to approximately the area of finding the bottom of the pile, and the lower part, the length of which approximately corresponds to the height of the folded reinforcing device. These parts of the element, working in tension, secured with mounting hardware. There are also barriers associated with this mounting device.

For fastening the upper and lower parts of the element, working in tension, use one of the following mounting accessories: socket connect the tion, clamping connection and/or a threaded connection with the use of a plate.

In one embodiment, as part of working in tension, use a threaded rod connected using a coupling sleeve with internal thread corresponding to the thread of the threaded rod. Thus, the ends of the upper and lower parts of the elements working in tension, fixed in sleeve coupling. The stoppers can be performed on the outer side of the sleeve coupling.

In the second embodiment, as part of working in tension, use the cable mounted using clamping connection. Thus, the ends of the upper and lower parts of the elements operating in tension, compressed together and locked. The stoppers can be performed on the outer side of the clamping connection.

In the third embodiment, as part of working in tension, use a round steel rod, mounted by means of a threaded connection plate, and the plate is provided with holes, which have a circular terminals, fixed screw connection on the other side of the plate. The stoppers can be attached to the plate or executed as part of the plate.

When installing a reinforcing device the proper position at the lower end of the pile or under the lower part of the reinforcing device must be deployed, to reinforcement details were distributed in the soles.

This extracting reinforcing reinforcing parts of the device is achieved using the included reinforcing device at least one of the following means of expanding the reinforcing parts: spring ring, swivel, explosive device and/or a sliding mechanism.

In one embodiment, as a means of expanding the reinforcing parts with a spring ring which is connected to the pipe and/or valve parts and located so that the spring ring expands and squeezes the tube and/or reinforcing details out.

Under the influence of sliding out of the pipe is forced extracting outward relative to the center of the pile reinforcement device comprising reinforcing parts, pivotally connected to the Central ring element.

In another embodiment, as a means of expanding the reinforcement details used an explosive device, located inside the reinforcing device when lowering the latter under pressure or lower pressure separately from the reinforcing device and at the same time.

However, the key in this case is the condition that the explosive device should be positioned so that the button in the explosion strongest influence on reinforcing details pushing them. Therefore, the explosive device should be placed in the reinforcing device next to the reinforcing parts or opposite reinforcing details.

When the actuation of an explosive device pressure from the blast affects reinforcement details, pushing them outwards and, thus, in a preferred embodiment, forming the uniformly distributed reinforcement soles.

This explosive device must have the capacity to exert the necessary pressure on the reinforcement details, but the force of the explosion should not be so great as to destroy the reinforcing device or damage the reinforcement details.

To achieve reliable retraction of reinforcing steel elements have an annular shape so that both ends of the reinforcing rods stacked around a Central ring element can move. The advantage of using the annular reinforcement part is the fact that it provides better reinforcement of soles than in the case when the reinforcing part is made, for example, in the form of direct round steel rod, as the annular reinforcement part is able to reinforce the soles on several levels, not only in one plane.

In addition, when using a ring of reinforcing steel elements during lowering pressure loannehemiah the last device will be protected from undesirable bumps and protrusions on the inner side through the longitudinal cavity of the pile.

In one embodiment, the reinforcement details are part of the reinforcing device, the lower part of which remains in a certain position while lowering the pressure of the reinforcing device and when the device is already in the desired position. Therefore, each reinforcing part has the shape of a sector of a ring and folded in with the rest of reinforcing details condition forms a ring corresponding to the inner diameter of at least one end-to-end longitudinal cavity of the pile, and when razdevanie reinforcing device forms a circular ring, the diameter of which is equal to the diameter of the lower end of the Foundation piles or greater than this diameter.

Data annular reinforcing parts are joined back to back so that the pipes connected with the gathered section of the annular reinforcing details, and reinforcement details vary in width, so that two adjacent reinforcing items will have different widths, giving you the opportunity to put one reinforcing part to another. The connection between these reinforcing parts can, for example, be made in the form of grooves in the armature parts, fastening reinforcement details may be omitted element, working in tension, and/or missing pipe. Thus, reinforcement details when razdevanie will be extended leash is at a certain distance, depending on the slots in the reinforcement details.

In the second embodiment, a reinforcing part formed by the network of rods and/or cables. This enables you to produce easy and inexpensive reinforcing details, able to reinforce the soles on several levels, not only in one plane.

To enhance the reinforcement of the sole reinforcing parts can be mutually connected, for example, with multiple cables in such a way that the reinforcement of the sole is made between the valve parts. Thus, the armature of the sole when the image soles in the plan will look like a spider's web.

In order to easily establish a Foundation pile in the desired position by means of its driving, and/or vibratory compaction, or install it into a pre-drilled hole, the pile must have a cylindrical shape, i.e. the cross-sectional area of the piles should generally be the same throughout its length. Thus it is possible to avoid the formation of empty space between the outside of the pile and the soil over the area of the piles with a modified cross-sectional area.

For the descent of the various instruments to the bottom of the Foundation pile through the interior of the piles in the past has a through axial cavity, the diameter of which depends on the descent of the tool is omenta and from compressive and tensile forces, depreciable pile.

For absorbing tensile forces in accordance with the present invention it is essential the fact that the pile transfers its fastening reinforcing device, and therefore, the reinforcing device is connected with the Foundation pile by means of at least one element, working in tension.

To facilitate driving or installation under pressure piles in the ground, reinforcing the device is additionally equipped with a tip of the pile located at the bottom of the pile so that the pile acts as a grounding rod during the driving of piles or install it under pressure.

To use the tip of the piles as part of the sole it is necessary that the reinforcing device was connected to the pile. To do this in a Foundation pile made several end-to-end longitudinal side channels, in General, placed at equal distances from the center of the cross section of the pile. Each end-to-end longitudinal side channel mounted element, working in tension, is attached below the mounting means for reinforcing device, including the tip of the pile, in turn, connected to a plug connection is preferably cylindrical portion of the piles with the help of elements working in tension.

In the famous Foundation piles to separate the tip is not used such a connection, therefore, in the extended sole formed by filling the reinforcing parts are much more difficult to provide a satisfactory connection between the tip of the sole and the bottom of the pile.

The tip of the pile is connected to the pile by means of several elements working in tension. In order for the elements working in tension, do not go beyond the piles or through the longitudinal cavity, a through longitudinal side channel for each element, working in tension. The number of required elements working in tension, not specified, but they must be located essentially at the same distance from the center of the cross section of the pile, in the thickness of the walls of the piles.

Dimensions end-to-end longitudinal side of the channel due to the dimensions of the elements working in tension, which should be sufficient to ensure the depreciation of tensile forces caused by, for example, the impact of wind power on the tower, connected with the pile.

To ensure separation of the tip of the pile from the pile after installation of the pile in the desired position of the elements working in tension, have at least one open area between the lower end of the pile and its tip. Depending on the soil type is the length of the free section and dimensions, within which sformirovat the sole between the bottom of the piles and the pile tip by pouring under pressure cured filler.

To transfer tensile forces from the Foundation down the pile to the tip of the pile are the elements working in tension, such as ropes, cables and/or rods.

If the elements working in tension, cables are used, installed, or by sealing in the thickness of the walls of the piles at several points in the end-to-end longitudinal side channels or free longitudinal movement in the sideways channel.

Cables should be made from a material that is strong enough to absorb the tensile stress and corrosion resistant by itself or with appropriate treatment. Moreover, it is necessary to avoid twisting and rotation of the elements working in tension, when installed in the side channels, as when the voltage it can cause stress concentration, resulting in reduced strength of ropes, and in the worst case they break.

If the elements working in tension, apply the rods produced, for example, stainless steel or similar material, these rods are mounted in end-to-end longitudinal side channels where they have the possibility of longitudinal displacement. Thus, when the tip of the pile is attached to the bottom section of the pile, for example during transportation or the environment piles in a predetermined position, the rods stick out above the top end it.

The advantage of using cables is that the connection between the Foundation pile and the connecting part of the Foundation or the Foundation is not completely accurate, while the cables are flexible, so maybe their lateral movement and, thus, the fastening.

The rods are used as elements working in tension, as a rule, are threaded in the upper part, and therefore, can be screwed to the connecting part of the Foundation or directly to the structural element of the building.

If the elements working in tension applied to the cables, attaching such elements working in tension, the mounting ring on the Foundation can be done using the cable clamp, the male connector of the Foundation or building structure, welding to this connector or termination in the connector.

In one embodiment, the cables attached to the mounting ring on the Foundation through the cable clamp, which can then be clamped to the rope leading down through the longitudinal side channels to the tip of the pile, always securely clamped. A necessary condition is the complete clamping of cables, because otherwise weakened the connection between the Foundation pile and Visele Asim Foundation can lead to tilting of the building.

To attach elements working in tension, to the tip of the piles used the following means of fastening elements operating in tension, to the tip of the pile, a threaded connection, a clamping connection, coupling, forming and/or performing in the bottom of the pile channel mainly U-shaped, through which can be skipped element, working in tension.

In one embodiment, the elements working in tension, are attached to the tip of the pile by means of a threaded connection, which is typically used when the elements working in tension, made in the form of a threaded rod on the end. This threaded connection may be made self-locking, and therefore, the release element, working on stretching from the tip of the pile is prevented.

In the second embodiment, as a means of fasteners to the tip of the pile is used clamping connection, as a rule, the cable clamp mounted in grooves inside the tip of the pile. These grooves inside the tip of the pile is made in the form of channels passing through the tip of the piles and located on the same line through the longitudinal side channels piles.

Channels in the tip of the piles or performed with a variable diameter that continuously changes direction the structure to the bottom of the pile tip, or performed with two different diameters, of which the largest diameter is located at the tip of the pile, face down. This allows you to install on the bottom edge of the tip of the pile wire cable clamp, which is due to the change in diameter has the focus, so that the rope is fixed at the tip of the pile.

This construction is usually performed with preservation of the smooth surface of the tip of the pile and, therefore, absent any ledge. This fact is advantageous for the installation of the Foundation piles in a predetermined position and the subsequent installation of the pile tip in a predetermined position, so as nothing is to interfere with the pointed tip of the pile to delve into the underlying soil.

In the third embodiment, as a means of mounting clamps, working on stretching to the tip of the piles used clutch, in which the lower part of the elements working in tension, after installing the latest in a through hole inside the tip of the pile bent so that they form a latch. To preserve the smooth shape of the tip of the piles these bends can be placed in the recesses.

In the fourth embodiment, the elements working in tension, can be embedded in the tip of the pile. That is, during the formation of the tip of the piles cha is th elements working in tension, is placed in a mold in which the molded tip of the pile. The elements working in tension placed in the casting tip of piles, can be rolled or bent to make the tip of the piles greater strength, as well as to strengthen the mounting of the tip of the pile.

In the fifth embodiment, during the formation of the tip of the piles can be formed by U-shaped channels located in such a way that the input and output openings of the upward part of such a U-shaped channel approximately corresponds to two opposite lateral channels piles.

Thus, the element working in tension, for example, the cable can reach from the top of the Foundation piles down through the longitudinal side of the canal, then down through the U-shaped channel of the edge of the pile, and then up again through the opposite end-to-end longitudinal side channel, which, in turn, ensures the absence of the tip of the pile fastening tools like clamps and various connections.

To keep all the soles in place through the longitudinal cavity and in close connection with the lower part of the pile during transport, Assembly and installation of the tip of the pile is constructed with the upper part, the form of which generally corresponds to the cross-sectional shape of at least one end-to-end ol the longitudinal cavity and which tapers upwards symmetrically relative to the centerline of the tip of the pile.

This form of the upper part provides the ability to install and partial fixation of the tip of the piles in end-to-end longitudinal cavity in the lower part of the Foundation piles during transportation and installation of the tip of the pile.

Moreover, due to the shape of the upper part of the tip of the pile is installed in the position in which it is almost impossible to move when faced with stone or similar obstacle during the installation of piles. This ensures the constant presence of the tip of the piles under the Foundation pile.

In addition, the narrowing of the upper part of the tip is designed so that during installation of the reinforcement device through the longitudinal cavity of the latter was pressing down on the cone-shaped portion and made of reinforcing elements to unfold and thereby to open in an outward direction with respect to a Foundation pile.

Below the tip of the piles has a tapering shape and/or form a flat disc. The shape of the outer lower part of the tip of the piles depends on the type of soil in which set the pile. For example, the tip of the pile with a conical bottom part will be used when the Foundation pile is placed under pressure by vibration and/or by ramming into the ground, as this form helps to break through the soil surface. When installing piles in point is evritania drilled hole may also use the tip of the pile with the bottom part in the form of a flat disk.

When the Foundation pile is installed in a predetermined position, the opportunity to lower the tip of the piles deeper into the ground under pressure, for example, by means of the piston. Between the pile tip and the lower part of the pile is formed by a space corresponding to the length of the free section of the element, working in tension.

This area will then be filled under pressure filler, form an extended sole, a diameter which exceeds the diameter of the outer perimeter of the Foundation piles, which will provide increased resistance piles tensile force acting on the resulting casting of the pile.

To further strengthen this extended soles on the bottom end through the longitudinal cavity piles installed reinforcing device being folded loosely secured status and contains several articulated reinforcing parts movably located at one end around a Central ring member, the free end of each reinforcing part has such a shape that he at least stands above the Central line of the upper part of the tip of the pile.

Through the use of piles with continuous longitudinal cavity provided during the installation of piles in a predetermined position to equip the pile reinforcing element and or filler with the formation of a durable sole for absorbing tensile forces.

In one embodiment, a reinforcing device is made with multiple reinforcing parts movably arranged around a Central ring element rotatably around this annular element and expanding outward from the bottom of the pile.

As this Central ring element can be applied to the ring on which is mounted a few reinforcing parts attached using a ring or swivel.

Reinforcing parts have a curved shape, and thus, part of the reinforcing details when it is installed on a Central ring element, which, in turn, is mounted in end-to-end longitudinal cavity piles, bent back over the centerline of the top of the pile tip. This bending and tapering upward shape of the tip of the piles are factors that provide the disclosure and dissemination of reinforcement details in the radial direction relative to the center of the tip of the pile, when lowering the reinforcing parts under pressure down over the tip of the piles pointed shape.

The outer diameter of the Central ring element may be approximated by the diameter of the through longitudinal cavity or to give him. And in fact, in another case, a reinforcing items must be folded inside of m is Nisha least at one point. While lowering under pressure through the longitudinal cavity they relate to its side walls, so that when lowering the pressure of the reinforcing device is moved along the guide.

Central ring element can be made in the form of a circular element with multiple recesses, which can be fixed reinforcement details of the fixing device. As the locking device may be a ring attached to the round element, allowing deepening blocked and reinforcement details recorded.

When using cables as elements working in tension, the tip of the piles and/or the lower part of the pile is equipped with recesses for placing the vacant lot of elements working in tension, this implies that when installing piles cables will not move up through the pile. In addition, these recesses is useful when the cables are fixed by means of casting in one or several points in the longitudinal side channels.

The tip of the pile or its lower part has recesses, which can be folded or bent up the rope. Thus, the cable can be hidden and thus prevent separation of the tip of the pile from the pile during transportation and installation of the piles.

These indentations could the t to be designed in the immediate vicinity of inlet ports for input elements, working on stretching at the tip of the piles or pits at the end of the pile. When unwinding the free section of the rope during the descent, under the pressure of the tip of the pile is not tangle-free cable, causing stress concentration at the action on the cable tension, which decreases the ability of a cable to work on stretching.

To further increase the resistance of piles in tension and reduce the possibility of lateral displacement of the pile through the longitudinal cavity is connected at least at one point with the outside of the pile at least one transverse and downward directed priming channel.

Data casting channels provide the ability to squeeze the filler at specified points along the working channel, i.e. at different levels, thus forming a tide that create resistance to tensile and compressive forces on the outer side of the pile. Through these casting channels can be skipped reinforcing bars, which interact with cured filler will form reinforced tide, having greater strength than unreinforced.

Filling the channels can be located in different planes perpendicular to the longitudinal axis of the pile, and, as a rule, at least one filling channel is located so that uhodnye hole filling channels evenly distributed approximately in the same plane on the outside of the pile, resulting through the discharge of material through the internal longitudinal cavity in the pile and filling the channels around the pile at different depths are formed tides. Thus, the resistance of the Foundation piles stretching increases, and, in addition, the Foundation pile is protected from lateral displacement regardless of the direction in which the pile affects the tensile stress.

As a substance injected into the surrounding soil layer for the formation of tides or soles, can be used in cement, concrete, liquid mortar or cured plastic. The main requirement for fill material is its ability to react or contact elements working in tension, the tip of the pile, and/or the lower part of the pile, and, possibly, the side surfaces of the piles. After curing of the filler is reliably associated with the pile.

To achieve even greater reliability and durability of connection between the filler and the pile surface of the individual parts of the piles may have irregular shape, for example, be covered with hollows or small protrusions. This improved adhesion, in turn, will increase the resistance of the Foundation piles stretching.

In one embodiment, a top casting channels are located so that h is on top of the tide will be formed at a depth of about 2 metres, that is where he can't participate in depreciation compressive and tensile load in the pile, but instead contributes to the stabilization of piles and to prevent its lateral displacement, which becomes a serious problem when installing piles in soft ground, for example in loose sandy soil.

To increase the strength of the Foundation piles and possible reduction of the sizes of the piles may be made of at least one outer reinforcing device. Such a device may be performed during formation of the pile or subsequent installation before installing, and will increase the resistance of the pile lateral displacement and damage to piles during installation.

To increase the speed and ease of insertion of the piles to the Foundation of the upper portion at least one end-to-end longitudinal cavity may be equipped with a thread, so that the insertion of the piles to the Foundation can be used with a threaded rod, bolt or screw with a nut.

In water-containing soils, such as sand, to form a cavity under the Foundation pile is difficult. To stabilize such a layer of earth or sand in the walls of the pile in its lower part may be formed with several holes. These holes are used for injection of the curing of the filler into the surrounding soil, t is to that solidification of the filler is stabilization of this layer and, thus, there is a possibility of formation of a cavity around the lower part of the Foundation piles without undesirable drop of the substance or liquid in the cavity due to the porous condition of this layer of soil or due to pressure in the water.

You can also create in the cavity of high pressure, preventing penetration into the cavity of the water from the layers of earth or sand during lowering under pressure through the pile reinforcing device and the molding of the sole, so that the extruding filler does not flow down the outer wall of the pile, and is pressed into the surrounding soil. You may alternatively also freezing the soil around the piles, and, thus, the ice will form a barrier around the cavity as long as the outsole do not be cast.

To avoid the use of reinforced concrete structures in the basement, make a connector designed for use in the foundations of the towers, mostly towers for wind turbine, and performed with the first mounting ring for attachment to the construction of the basement and the second mounting ring for mounting to the tower, while the first and second connecting rings bonded at least one connector.

The connector is located as a transitional element between the lower part of the tower and Foundation, there are two mounting ring will connect the La must be of a suitable size corresponding mounting portions of the bottom of the tower and Foundation. Therefore, the ratio of the outer circumference of the first mounting ring to the outer circumference of the second mounting ring can be the following:

- the size of the outer circumference of the first mounting ring is approximately equal to the size of the external circumference of the second mounting ring;

- the size of the outer circumference of the first mounting ring is smaller than the outer circumference of the second mounting ring; or

- the size of the outer circumference of the first mounting ring larger than the outer circumference of the second mounting ring.

Typically, the foundations of the tower absorbs two types of forces:

- vertical load (compressive force) in the form of its own weight of the tower and any additional structures, such as a windmill, and

- the time from exposure to the force of the wind on the tower and possible additional structure. Currently depreciated in the design of the Foundation as a uniformly distributed tensile stress and compressive stress.

Typically, the dimensions of the foundations of the tower set in such a way that it provided depreciation only compressive forces. The Foundation is difficult to absorb the tensile stress. When using a typical Foundation with reinforced concrete design tensile stress substantially depreciated own weight Foundation.

When installation is ke high towers tensile and compressive efforts increase to a much greater extent, than the dimensions of the Foundation, it is therefore necessary to provide for the amortization of traction. Best solution in this case may be the use of pile Foundation, in which the piles are designed to provide the best cushioning a relatively large tensile forces and transfer it to the surrounding soil.

In the foundations of the high towers or towers erected on soft soil, usually applied in the stacking pile Foundation under the entire Foundation to provide the same carrying capacity of the entire Foundation from the point of view of the compressive force. However, this is not the best way to provide the same carrying capacity from the point of view of the squeeze effort, as the Foundation piles located closer to the center of the tower, not enough distance from the vertical Central plane of the tower for absorbing tensile forces corresponding to the size of the piles. This method of laying the Foundation entails the use of an unnecessarily large number of Foundation piles for depreciation efforts, in particular tensile forces.

In accordance with this invention the number of piles can be reduced through the use of the described connector in connection with piles of special design, with several piles located on the sufficiency of the face-to-face distance from the center of the tower and therefore are used in an optimal way to absorb tensile forces, corresponding to their size. This property is an important advantage of the invention, as the cost of the Foundation piles, including transportation, installation in the ground and attach to the connector, is estimated at $ 4000-8000 Danish kroner, and the length of each Foundation pile is 15-30 m

To ensure optimal distribution of tensile and compressive efforts, the result of the influence of its own weight and the force of the wind, it is preferable to use such a design of the connector, in which the size of the outer circumference of the first mounting ring larger than the outer circumference of the second mounting ring.

For uniform distribution of tensile and compressive forces acting on the connector, the latter may be equipped with a first mounting ring having at least two holes for attaching the connector to the Foundation structure, evenly distributed on the first mounting ring. The distribution of holes in the first mounting ring determines the optimal transmission of tensile and compressive effort regardless of, what is the effect of wind on the tower. Holes, which can be equipped with internal thread, provide the possibility of mounting the connector to the Foundation through a connection to the bolt and/or nut. That is the second method is more convenient and reliable, than, for example, welding on site. In a preferred embodiment of the connector around the circumference of the first mounting ring is made 20-30 holes.

To run the connector from billet smaller and at the same time with the mandatory provision of depreciation transferred from the tower on the Foundation design of tensile and compressive efforts, the first mounting ring and at least one connector connected to at least one reinforcing element. To save the static state data of the reinforcing elements can be either evenly distributed around the first mounting ring by means of a continuous connector or distributed and is connected with several separate connectors or fixed in one position specified by means of statistical calculations for depreciation efforts taking place most of the time, for example in areas with one predominant wind direction, resulting in the tower unidirectional influences the strength of the wind.

In a preferred embodiment, the connector on the first mounting ring is made of an even number of holes and reinforcing parts, which are evenly distributed around the first mounting ring connected to a continuous connector. Openings and reinforcement details are thus, h is about each reinforcing part is between the two holes at equal distance from them. In addition, the available space for mounting and Dismounting bolts and/or nuts.

For uniform distribution of tensile and compressive effort on the last connector can be equipped with a second mounting ring having at least two holes for attaching the connector to the tower. These holes are evenly distributed on the second mounting ring. The distribution of holes on the second mounting ring determines the optimal transmission of tensile and compressive effort regardless of, what is the effect of wind on the tower. Holes, which can be equipped with internal thread, provide the possibility of mounting the connector to the bottom of the tower through connection with the bolt and/or nut. This method is more convenient and reliable than, for example, welding on site.

In a preferred embodiment, the connector on the second mounting ring is formed of 15-30 holes. The number of holes in the second mounting ring does not necessarily coincide with the number of holes in the first mounting ring, however, it is given by the size of the connection bolt/nut and the space required for its installation and dismantling.

In another preferred embodiment, the connector design allows mounting to a Foundation structure using bolts and/or the AEK, when this connector is either made in one piece with the lower part of the tower, or welded to the tower. This design allows the production and transportation of the connector together with the tower and, therefore, to avoid the need to fit and install the connector on the tower.

The connector consists of a continuous connecting elements or frangible connecting elements and the two mounting rings, and first and second mounting rings can be made in accordance with at least one of the following combinations:

the first and the second mounting ring is made annular,

the first ring is made in the form of a plate, and the second is made annular,

the first is made annular, and the second is in the form of a plate, and

the first and the second mounting ring are designed in the form of plates.

When mounting the connector containing the continuous coupling element and the first and second mounting rings are in the form of plates (closed connector), access for attaching the connector to the Foundation structure and the lower part of the tower can be accessed via a hatch located in the disk of the second mounting ring or in the connecting element.

The advantage of using a connector, made in the form of a closed element, consists in the possibility of protection bolts ginamit corrosive environment, for example sea water.

To fit the connector to different types of towers and Foundation designs used connectors the following geometric shapes: a truncated cone, truncated pyramid, prismatoid or obelisk.

When using connector instead of reinforced concrete structures in small or medium wind turbine is advantageous from the industrial point of view is the use of a connecting element in the form of a truncated pyramid, prismatoid or obelisk, as these forms are simple in construction and manufacture and therefore inexpensive.

In a preferred embodiment of the invention, the connector is made so that the entire outer circumference of the second mounting ring attached continuous connecting element to the entire outer circumference of the underlying first mounting ring, both mounting rings are ring-shaped. This embodiment of the invention allows to reduce the dimensions of the continuous coupling element and install a large amount of reinforcing steel elements, evenly distributed around the first mounting ring. In addition, between the lower part of the tower and the Foundation formed a natural pair.

Another aim of the invention is to provide a method of use of the connector when laying the foundations of the tower.

For used what I described coupling element when laying the foundations of the tower should:

- to place the Foundation on the soil and/or ground,

to install the connector directly on the base and attach it to her, and

to install a tower on the connector and attach it to him.

In addition, the base can include at least one Foundation pile, placed in the ground at a distance from the center of the basement and set at an angle of 0-90 degrees, preferably 0-45 degrees to the vertical plane.

The fact that the pile is at an angle to the vertical plane, provides greater load bearing capacity of the Foundation structure, since the thickness of the earth around the piles increases the load bearing capacity of the Foundation design in relation to the tensile force. When piles are located close to each other, they are able to get the same mass of soil. However, the installation of piles with an inclination with respect to each other, each pile pulls a large mass of soil or injected into a large mass of soil. However, the most preferred angle from the vertical plane is the angle of 0-45 degrees, as the bearing capacity of the Foundation structure from the point of view siraudeau effort is greatly reduced by the installation of piles at an angle more than 45 degrees to the vertical plane.

The method of installation of piles and reinforced what I base by means of a reinforcing device includes the following steps:

installation of piles in a predetermined position under pressure by ramming or by dropping in a pre-drilled hole

- opening under the pressure of the folded reinforcing device through at least one end-to-end longitudinal cavity of the pile,

- upon reaching the reinforcing device of the lower end of the pile moving it under pressure for some distance down; driven means expanding the reinforcement details of the reinforcing device with education thus network consisting of at least reinforcing parts of a reinforcing device, and

- supply under pressure through the specified at least one end-to-end longitudinal cavity piles cured filler, so that the lower part of the pile and the expanded reinforcing device are sealed in a single casting for the formation of the reinforced soles, the dimensions of which exceed the dimensions of the Foundation piles.

This method allows you to use a Foundation pile as a relatively compressive and the tensile load, which occurs under the influence of the design, which are attached to the Foundation. Also this method allows you to install a reinforcing device in a predetermined position and to push his education reinforcement uniformly distributed in the sole, and thus is velicity resistance of the pile compressive force, caused, for example, by the action of wind.

The choice of method of installation of piles: under pressure by ramming or by dropping in a pre-drilled hole depends on the type of soil in which to install the pile. In very soft soils and areas not subject to vibrations applied setting under pressure or lowering in a pre-drilled hole. In areas with hard ground and away from other building structures can be used piling. However, when the driving of piles, you must make sure that the pile is made of a material having sufficient strength to resist repeated impacts, or the construction of piles equipped with the necessary external reinforcement.

It is important that a significant part of the upper part of the reinforcing device when you install did not remain in the Foundation pile, as well as to achieve reinforcing device of the lower end of the pile it was omitted under downward pressure for some distance, so as to ensure that extracting reinforcing device without interference from the bottom of the pile, which may prevent full razdviganii reinforcing device in the underlying cavity.

During injection of a filler in the space between the reinforcing device and the bottom of the pile this filler fills in the elements, working the e tensile, together with the reinforcement details provide the sole greater resistance relative to the tensile and compressive efforts, which it is exposed.

In an embodiment of the invention in which a reinforcing device comprises a pipe for elements working in tension, together with the reinforcement details filled in the sole, so that they provide the sole or the pile a large resistance relative to the tensile and compressive efforts, which it is exposed.

To accommodate the reinforcing device to the desired depth, the above method can be added to the next stage. After installation of Foundation piles the pile tip is lowered under pressure and/or clog deeper into the earth by means of the piston and/or sabinoso tool, so that the distance between the tip of the pile and the lower part of the pile is largely corresponds to the length of the free section of the element, working in tension.

For driving the reinforcing device of the piles deeper into the earth can be used, for example, a piston or nabivochnyj tool, and a piston operated by hydraulic, pneumatic or electric motor, which lowers the reinforcing device under pressure with constant velocity until then, until you stretch the elements working in tension, is not apart reinforcing details.

In the case when the elements working in tension, are used rods, reinforcing device together with the tip of the piles can be omitted under pressure in an underlying layer of the earth to an arbitrary depth, but with the possibility to inject the filler in such quantity that it will capture the tip of the pile and the bottom of the pile and at the same time will form the sole, the size of which exceeds the dimensions of the piles. If the space between the tip of the piles and the pile gets too big, it will be almost impossible from a technical point of view, upload it such a large mass of filler so that these elements are connected.

Depending on the soil conditions to the above method you can also add another stage, namely, that before sinking under the pressure of the folded reinforcing device below the bottom of the pile to form the cavity using the device for the preparation of the soil.

In addition, the device for preparing of the soil can be used, for example, to remove substances sobivusele in the pile and climbing the pile during driving. As a device for the preparation of the soil can be used, for example, mechanical drilling rig, sand-blast apparatus, a device for supplying compressed air cleaning device at high is a t or a similar device, which can be lowered through the pile to remove unwanted substances from the inner part of the pile or from under the bottom of the pile.

Select the device type for the preparation of the soil depends on soil conditions, different primers are different types of devices for soil preparation. For example, in soils with a high content of sand, the ideal solution is washed out of the sand using, for example, devices for high pressure cleaning.

In the case of the formation below the bottom of the pile cavity using the device for preparing the soil to the above method may be added the following stages:

- upon reaching the reinforcing device of the lower end of the Foundation piles it lower pressure in the lower cavity up until the stoppers on the top of the reinforcing devices will not be installed in cooperation with the inner side of the pile, and

then the reinforcement details are responsible to ensure that the reinforcing device is in tight connection with the lower end of the pile.

These steps ensure the placement of the reinforcing device in close proximity to the bottom of the pile, and, thus, reinforcing device and the lower part of the pile is filled with filler together.

The application of the brakes also avoids the destruction of the filling of the bottom ring is breznay part of the pile under the influence of compressive forces from the Foundation, as the weight, causing the occurrence of compressive efforts, is transferred from the pile on the bottom through the retaining surface of the stoppers, the total area of which is larger than the cross-sectional area of the lower part of the tubular piles.

For expanding the reinforcement details in the cavity to provide optimum reinforcement of the sole to the above method is added to one of the following steps, as a means of expanding the reinforcement details use:

- snap ring, which pushes the tube out and thus forces you to move outside reinforcement detail thanks to its hinged connection so that the network is formed, containing pipes, reinforcement details and the Central ring element,

- sliding mechanism, the controlling valve parts when the latter fall out under the influence of gravity, when reaching a reinforcing device cavity under the pile so formed network containing pipes, reinforcement details and the Central ring element,

- explosive device, pushing the reinforcement details of the explosion.

All three of the above stages, aimed at extracting reinforcing parts lead to the fact that the reinforcing parts are common in the sole, to the extent possible, resulting in the durability of the soles of growing the A.

The sliding mechanism is a mechanism which in addition to expanding the reinforcing parts provides reinforcement pieces, fixed in a certain position, protection from piles up until the reinforcing parts are not molded in the sole. The sliding mechanism can be actuated by pressing on it with the piston moving down in the longitudinal cavity of the pile.

When using reinforcing device together with the tip of the pile extracting reinforcing parts occurs by pressing the piston ring element reinforcing device, after which the reinforcement details are conducted through the connection between the pipe and the reinforcing part, whereby the reinforcing parts are moved apart to the outside.

For the formation of the cavity associated with the lower part of the Foundation piles, preferably having a cylindrical shape, the method specified in the beginning, may be added the following stages:

device for the preparation of the soil is lowered down through the working channel,

- treated layer of soil under the pile using the device for preparing the soil,

- form under the pile cavity,

pulling device for preparing the soil up through the working channel.

As a device for the preparation of the soil can be one of many possible devices that can be lowered downward is through the longitudinal cavity in the pile, for the formation of a cavity in the surrounding area of soil. This can be, for example, mechanical drilling rig, which during lowering her through the longitudinal cavity in the pile is built, and upon reaching the lower end of the pile splits and drill the surrounding ground to a specified diameter.

As a device for the preparation of the soil can also be used explosive device that is lowered down through the longitudinal cavity in the pile and set in the space between the tip of the piles and the pile, and then detonate. Thus, under the action of the pressure force of the blast wave is formed cavity. However, this method must be used with caution, as the explosion can damage the elements working in tension, the tip of the pile and the bottom of the pile.

As an option can also be used leaching under high pressure. In this case, the device for washing under high pressure down through the longitudinal cavity in the pile in the discharge space between the tip of the piles and the pile, with the excess soil and water pumped through the working channel. Thus, there remains a cavity that can be filled with a filler, which will be backfilled with the specified details.

However, in some types of soil using the device for the preparation of the soil is presented and is unnecessary. Instead, you can apply the injection of the filler through a long pipe, filtered through a tubular Foundation pile. This method is best used on soft soils.

Can also be used the tip of the pile, protecting the pile from substances that when driving piles can penetrate into the pile and climb on it.

To increase the tensile strength of piles in tension and compression and to minimize the risk of lateral displacement to the aforementioned method can be added another stage, in which formation around the outer perimeter of the piles at least one of the tide at least one longitudinal cavity piles injected mass of cured filler coming out through the pouring channels associated with this cavity.

This step is performed directly after the installation of piles in a predetermined position or within a technological lifetime of the piles. The result can be adjusted, for example, the curvature of the pile or error in the position of the piles. Thus, the possible adjustments arising installation errors in the lateral direction.

Filling the channels can be further used to remove piles at the end of the technological life of the building, as at present during the demolition of the building required the removal of the mother of the La from the earth to the maximum possible depth. Filling the channels can be further used for extrusion or spraying lubricating agents, capable of dissolving the cement mixture or to coat the outside of the pile, making it easy to remove.

However, when removing piles can cause problems with the soles.

Therefore, as a workaround, you can use trim elements working in tension. If the elements working in tension, are located in the side channels, but not embedded in them, the pile can be removed, leaving the ground the tip of the pile and the bottom.

If the sole is attached to the bottom of piles, you can use a longitudinal cavity within the piles for lowering an explosive device that is placed directly on top of the sole and thus explode the sole or separate it from the piles upon detonation of an explosive device that allows you to pull the pile.

In case the piles with side channels, in which the elements working in tension, can make free longitudinal movement, piles can be composed of modules in order to facilitate their transportation and production. Thus, at the place of production or driving piles one by one add modules and only let in the elements working in tension, through each module.

Thus, it becomes possible to install with the AI in places where it is unknown at what depth should immerse the lower part of the pile. However, it is necessary to apply the elements working in tension, such length that regardless of the depth of installation of piles, the portion of the element would be issued over the top edge of the pile.

To prevent dissolution of the filler, introduced during formation of the soles, before installing reinforcing device and paint the soles in the cavity under the pile can be entered protective fluid, which prevents ingress of water into the soil layer prior to the curing of the filler. As such a protective liquid may be used a mixture of, for example, gelatin, cement grout or similar material, which may be displaced introduced by the filler, when the sole of the cast piles. You can also use frozen soil.

Detailed description of the invention

On figa, 1b and 1C shows how the reinforcing device is lowered under pressure through the pile 2 and deploy in the underlying cavity 3.

Reinforcing device 1 contains reinforcing parts 4, which are connected by a ball joint located at the center of the annular element 5 and is connected with the Foundation pile 2 using elements 6, working in tension.

Foundation pile 2 is installed in the ground so that its upper end rises above the surface 7 of the earth.

Figure 2 is zobrazeno reinforcing device 1, which is in closed position in the lower part of the Foundation pile 2. Reinforcing device 4 pivotally connected with located in the center of the ring element 5, which is connected with elements 6 by means of a threaded connection 11 with the use of a plate.

The lower and upper elements 6 are connected by a connection 9, in this embodiment, a threaded connection, with the use of a plate. The connection 9 is equipped with brakes 8.

Figure 3 shows the reinforcing device 1, which is located directly below the bottom of the pile 2 and located in a partially extended position.

The reinforcing parts 4, consisting of a network of rods, connected with the sliding mechanism 10 provides uniform extracting the reinforcing parts 4 at the specified angle.

Figure 4 depicts the fully extended reinforcing device 1. The mechanism 10 holds the reinforcing parts 4 in place until such time as the sole (not shown) will not be cast.

The stoppers 8 is secured in place in such a way that they rest against the bottom edge of the Foundation pile 2.

A number of cables 12 connects the reinforcing parts to each other, to provide additional reinforcement of the sole (not shown).

Three 2-4 illustrates the rotation of the reinforcing parts 4 around the ring element 5 when razdevanie the Armira the feeder 1.

Figure 5 shows a top view extended reinforcing device 1 in which the reinforcing parts 4 are connected by means of a cable 12 with the formation of a reinforcing network for the reinforcement of the sole (not shown) like a web.

Figure 6 shows the annular element 5 with upright circular wall 13, which includes a number of recesses 14 and the annular edge 15. The number of recesses 14 in the wall 13 corresponds to the number of the reinforcing parts 4.

In the end portion of the reinforcing parts 4 is a bearing 16, the internal diameter of which coincides with the external diameter of the annular flange 15, so that the reinforcing parts 4 can be mounted on the annular edge 15. Recesses 14 allow the reinforcing parts 4 to rotate around the annular edge 15.

On figa shows a view in section of a reinforcing device 1 located inside the Foundation pile 2. The connection 9 is made in the form of a threaded connection plate, and plate-part of this connection is divided into four parts and has continued in the form of the stopper 8.

On fig.7b shows the view in the context of spaced reinforcing device 1, in which the stoppers 8 rest against the lower edge of the Foundation pile 2.

On Fig depicted Foundation pile 2, installed in the ground 17. In connection with the lower part 18 of the Foundation pile 2 is Ipanema cavity 3, located under the lower part 18 of the Foundation pile 2. The cavity 3 is formed due to the fact that through the Foundation pile 2 is omitted pipe 19, through which is fed a liquid, air, etc. so that excessive substance is displaced upwards in the space between the pipe 19 and the inner side of the Foundation pile 2.

Depending on the pressure applied to the Foundation pile 2, and its length variant in which excessive substance absorbed. In addition, to remove excess matter from the cavity 3 may be used for some combination of the forces of suction and pressure.

Figure 9 shows the lower part 19 of the Foundation pile 2, which is equipped with a reinforcing device 22, in another embodiment. The device contains a number of tubes 20, each of which is omitted the cable 21 connected to the lower part of the pipe 20 through the cable clamp 23. In the upper part of the pipe 20 is set to the stoppers 24. As shown in the drawing, the stoppers 24 are l-shaped cross-sectional shape.

Between the pipe 20 is installed snap ring 25 shown on this drawing in a compressed state, and the holding tube 20 along the inner side of the Foundation pile 2 so that the parts 26 and the stoppers 24 are guides for reinforcing device 22 when lowering the reinforcing device under pressure inside the funda is entei piles using, for example, the piston 28.

Reinforcing device 22 also includes an annular reinforcement part 26 fixed at one end can move around the ring element 27. In addition, the reinforcing part 26 by means of the swivel connection 29 is attached to the pipe 20 can move.

Figure 10 shows a reinforcing device 22, is lowered by the piston 28 under pressure under the Foundation pile 2 in the cavity 3. Snap ring 25 unclenched and presses the pipe 20, pressing the lower part of the pipe 20 to the outside relative to the center of the Foundation pile 2. Under the influence of sliding of the lower parts of the tubes 20 of the reinforcing part 26 is also forced to move apart through the swivel 29, so that the parts 26 are uniformly distributed in the base (not shown) in the radial direction.

In the upper part of the pipe 20, the stoppers 24 are logged on to the site, and therefore, when the tension of the cables 21 of the lower part 19 of the Foundation pile 2 abuts against the stopper 24.

In the condition shown at 11, the piston (not shown) is removed, and the mass of the matter-filler 30 fills the cavity 3 and the inner part of the Foundation pile 2, filling the reinforcing device containing pipe 20, the reinforcing parts 26 and ring elements 31, together with the bottom part 19 of the Foundation pile 2 and forming the sole 32, the dimensions of which exceed the dimensions of the lower part 1 of the Foundation pile 2.

On figa shows a cross-section of the Foundation pile 2, which is equipped with a reinforcing device 22 containing a number of tubes 20, through which are passed the cables 21. From the drawing it is seen that the outer diameter of the stopper 24 coincides with the inner diameter of the Foundation piles 2.

On fig.12b depicted reinforcing device 22, is extended below the bottom of the Foundation pile 2. The drawing shows that the reinforcing part 26 is extended outward from the centre of the Foundation piles 2 and together with the ring elements 31, the pipe 20 and the cables 21 form a reinforcing network, located at the desired depth below the bottom of the Foundation pile 2 in the cavity 3.

On Fig depicts another embodiment of a reinforcing device 33, containing a number of tubes 20, through which are passed the cables 21, attached to the lower ends of the pipes 20 and the ring elements 34, and the upper ends of the tubes 20 is attached to the stoppers 24, each of which in this embodiment is connected with two pipes 20. The stoppers 24 are l-shaped form that allows them to cling to the bottom edge 19 of the Foundation pile 2.

The ring elements 34 are here shown in the extended position, and most likely that they moved apart by means of an explosive device (not shown). Here is shown the ring elements 34 of the two dimensions, p is this the adjacent annular elements can be nested within each other and are connected by means of a cable 21 or pipe 20, which are passed through the recesses 35.

On Fig depicted Foundation pile 36 having a through longitudinal cavity 37 and the lug 38, and is also equipped with a number of longitudinal side channels 39, each of which has an element 40, working in tension, in this embodiment represented in the form of a rope.

Element 40 lower end connected to the tip 38 of the pile. In the depicted embodiment, the means 41 of the fastening elements 40 to the tip 38 is made in the form of through-channels 42 in the tip 38 at the entrance to the handpiece 38 have the same diameter, and in the lower part of the tip 38 is another, larger diameter. Thus, the elements 40 can be secured, for example, using a cable clamp (not shown).

Below the tip 38 has a constriction 43, providing the driving of piles 36 in the ground. Top tip 38 has an upper division 44 whose shape corresponds to the shape of the inner end-to-end longitudinal cavity 37 of the pile 36.

The upper part of the upper section 44 is made with a constriction 45 fitting a centering tip 38 at the bottom of the pile 36. At the same time, this narrowing performs another function: to push the reinforcing part 47 when installing reinforcing device 46.

Reinforcing device 46 also includes an annular elements that have a certain amount Armat the situations of the parts 47, each of which is made curved.

In this embodiment, at the tip of the pile is made of the recess 49, which are used for laying the free end 50 of the element 40, working in tension when the tip 38 is in direct connection with the lower part of the pile 36.

On Fig shows the four States of piles 36 during its installation. In condition A (leftmost image) tip 38 is in direct connection with the pile 36. From the drawing it is seen that the upper section 44 of the tip 38 is placed inside the through longitudinal cavity 37. The free ends 50 of the elements 40 are positioned in the recesses 49 of the tip of the piles 38 in wound condition. The dotted lines indicate the offset of the axis of the handpiece 38 relative to the pile 36, which takes place during the application of force, shown by arrow, from the inside through the longitudinal cavity 37 at the tip 38, pushing him further down, so that the free ends 50 of the elements 40 are extended.

In the state In the tip 38 is lowered under pressure relative to the lower end of the pile 36, so that the free ends 50 of the elements 40 is released from the recess 49 by unwinding.

Reinforcing device 46 containing ring element 48 with installed curved reinforcing details, down through the cavity 37.
