The invention relates to the construction and can be used for the construction of load-bearing foundations, fixing various mechanisms and devices on the ground, including in the conditions of permafrost soils in the rotational dip in the ground (drilling or screwing) sections of the working tool, and doing preparatory work.

Currently there is the problem of low performance of the preparatory works for drilling or screwing arising due to the inability in most cases to connect the cartridge with a section of the working tool (screw piles or auger section) in any position except vertical. A large amount of time spent on the connection (disconnection) of the additional parts of this tool among themselves.

In addition, when the rotational immersion of the working tool (when drilling or screwing screw piles), there is axial movement of the tool in the Chuck, transmitting torque, which leads to loss of control and, as a consequence, - uncontrolled dive of the working tool into the ground.

A device for screwing piles, which before immersion of the working tool is mounted on the upper end of the pile and through the slots transmits torque to the pile when it wrestlingmania [Irodov M. D. The use of screw piles in construction. - M., 1968, p. 110].

To use this device is only possible after the working tool (pile) installed with additional lifting devices in vertical position.

It is also known a device for drilling [patent US 4334392], in which the attachment screw section to the second bushing cartridge rotation mechanism is carried out by means of the locking finger, and due to the multi-faceted shank screw on sections of the transmission of the torque when drilling.

The disadvantage of this device is the inability to connect the cartridge with a screw section which is on the ground or in the vehicle in a horizontal position, and the clamping Chuck with drill tool this construction is possible only in an upright position, usually with the use of a ladder or from the vehicle at a height of.

It is also impossible to carry out laying in the horizontal position of the working tool without fully detach it from the cartridge.

The specified device has limited functionality and does not allow to connect the cartridge with a screw section at any position except vertical.

The closest to the claimed is a device for screwing R�working tool screw piles [RF patent №2374391] containing the rotator, gear, cartridge, made in the form of a sleeve with a longitudinal groove and a horizontal axis. The lower part of the cartridge is provided with grippers, each of which has a handle with a spring loaded clamp, and grips have a non-through grooves, the horizontal axis is made with cylindrical protrusions at the ends, and the longitudinal grooves of the sleeve is made of stepped-closed.

The device may be provided with a second horizontal axis, a removable cover plate, consisting of two plates, which are provided with holes under the horizontal axis, and in one of the plates holes are shaped in shape and at one end of the horizontal axes is made bevels similar figure shape.

In this device as a work tool uses a standard pile, in the form of a tubular part with cylindrical protrusions at the ends of the horizontal axis, installed in the upper part (head) [RF patent №2374391].

Device using cartridge allows you to capture the pipeline (section of tool) piles, was lowered into the ground, cylindrical protrusions at the ends of a horizontal axis fixed in its upper part. After completing the capture pile it up, carry to the place and screwing, transferring torque, tighten.

The disadvantage�known device is that when screwing with it a working tool (pile) has the possibility of axial movement relative to the socket.

However, a disadvantage of the working tool (piles) is the lack of rigid axial fixing of the cartridge and, as a consequence, the presence of the axial movement of the working operations.

The axial movement allows for the drilling section of the working tool (screw section) using the known device. When using the known device in the cartridge, transmitting torque in the rotational dip in the ground occurs, the axial displacement of the screw section, which leads to uncontrolled dive it into the ground.

In addition, the disadvantage of this device is the use of the horizontal axis with the cylindrical protrusions in the upper part of the working tool (piles), or an additional device in the form of a replaceable pads and the second axis, as each of them complicates the process of preparing for rotational immersion of the working tool into the ground.

In relation to the device for rotary dip sections of the working tool into the ground solve a technical challenge is to expand the technological capabilities of the proposed device due to its use not only for screwing screw piles, but also for BU�communicating with the screw sections at a reliable, accurate and safe dive.

The task in relation to the device for rotary dip sections of the working tool into the soil is solved in that the device containing the rotator, gear and cartridge, made in the form of a sleeve, the lower part is provided with a grip and spring-loaded latches, according to the invention the grip with clamps made in the form of a plug, the axis of each of the latches and diametrically perpendicular to the axis of rotation of the cartridge, and in the upper part of the cavity of the cartridge is performed pocket with a cylindrical transverse groove and a through groove, made by the rotary element on the tip section of the working tool, and spring-loaded latches provided with a locking rods and made of longitudinal grooves on the tip section of the working tool

In respect of sections of the working tool solve a technical problem lies in an accurate, controlled immersion of the latter in the soil, eliminating axial movement.

The problem is solved in that section of the working tool made in the form of the housing with the wedge according to the invention is provided with a rotation mechanism, comprising two rotating heads, kinematically interconnected, located on the outer lateral surface sections of the working tool in the upper and lower part and to�nematicide associated with rotary locking element in the head section of the working tool, comprising a transverse projection disposed on the upper end of the tip, and longitudinal grooves on its side surfaces.

In this section of the working tool may be formed as a rod, screw sections or piles.

The inventive design of the device for rotary dip sections of the working tool into the ground and sections of the working tool are a group of inventions, of which the one section of the working tool is intended for use in another. Common technical idea is confirmed by the overall technical objective and function.

Device for rotary dip sections of the working tool into the ground combined in one application with a section of the working tool on the basis that the latter ensures the most effective use of this device.

Spring-loaded clamps plug ensures reliable connection of the cartridge with the section of the working tool and allow you to take the weight of the raised sections of the working tool with the safety margin.

Ease of use when performing the operation and simplicity of design of clamps makes the fixing unit of the cartridge with the section of the working tool is safe and secure.

The supply section of the working tool rotation mechanism, comprising two rotating heads, key�ematichesky connected, located on the outer lateral surface sections of the working tool in the upper and lower part thereof and kinematically connected with the rotary locking element in the head section of the working tool, ensured reliable and safe lifting of sections of the working tool from the horizontal in the working position and Vice versa, as well as of fast connection (disconnection) of these sections in the rotational dive (ascent) in the soil of the inventive device, precluding axial movement of the section relative to the socket.

The cartridge fixing section of the working tool by setting waypoints in the longitudinal grooves of the tip section of the working tool when it is in a horizontal position on the ground or in the vehicle.

In the future, after lifting sections of the working tool and the full establishment of headroom inside the cartridge, the rotation of the lower head of the lateral surface of the pipe section of the working tool, in this case, through the kinematic connection of the rotary element on the tip section of the working tool is rotated, is fixed at the cylindrical protrusions of the pocket groove in the upper cavity of the cartridge, which prevents axial movement of the section of the working tool relative to the Chuck. Describes how to consolidate with�functions of the working tool in the Chuck allows to reduce the time for preparatory work during the installation of sections of the working tool before drilling.

The technical result achieved by the invention consists in a reliable and safe execution of lifting the working tool from the horizontal in the working position and Vice versa and rapid connection (disconnection) of sections of the working tool with the rotational dive (ascent) in the soil of the inventive device, precluding axial movement of the section relative to the Chuck,

The invention is illustrated by drawings, in which: Fig. 1 - General view of the claimed device of Fig. 2 - cartridge with a screw section in the locked position; Fig. 3 - view And Fig. 2; Fig. 4 - cross section b-B of Fig. 3; Fig. 5 - cartridge with clamps; Fig. 6 - section b-b of Fig. 5; Fig. 7 auger section; Fig. 8 - remote element G of Fig. 7; Fig. 9 - remote element D of Fig. 7.

Device for rotary dip sections of the working tool into the soil consists of rotator 1, reducer 2 and the cartridge 3 is arranged in the form of a sleeve (Fig. 1). In the drawing (Fig. 1) shows also a section of the working tool in the form of a screw section 4.

The cartridge 3 (Fig. 5) consists of a body 5 and two spring-loaded clamps 6 located in the lower part of the housing 5, the axis of each of the latches 6 are perpendicular to the axis of rotation of the cartridge 3.

In the upper part of the internal cavity of the cartridge 3 is pocket 7 with the cylindrical protoc�Oh with continuous transverse groove 8 (Fig. 5 and 6).

The lower part of the body 5 of the cartridge 3 is in the form of a "fork" with two protruding elements that have spring-loaded latches 6.

Immersed in the soil of the inventive device, the section of the working tool (auger section 4) (Fig. 1) consists of a screw pipe 9 (Fig. 7) with the screw coils 10, the cap 11 with the multi-faceted surface in the upper part and the internal cavity 12 in the lower portion of the screw pipe 9.

On the side surfaces of the cap 11 (Fig. 7) diametrically to each other arranged two longitudinal groove 13, the width corresponding to the diameter of the retaining rods 14 (Fig. 3) clamps 6 mounted on the cartridge 3 (Fig. 1).

At the upper end of the cap 11 is a transverse protrusion 15 and the rotary locking element 16 (Fig. 4 and Fig. 7), which has the possibility of rotation around its vertical axis, which by the rod 17 (Fig. 7) extending through the cap 11, kinematically connected with the rotation mechanism 18 (Fig. 8 and 9) inside screw pipe 9, which is designed to manage the locking element 16. Lateral projection 15 and the locking element 16 correspond to each other in size.

The rotation mechanism 18, which includes two rotating heads 19 and 20 respectively are kinematically interconnected, is located in the top and bottom of auger tube 9.

Device�istwo for rotary dip sections of the working tool into the soil works as follows.

To auger section 4, a horizontal rotator is supplied with 1 cartridge 3 (Fig. 1).

Longitudinal grooves 13 on the tip of the screw sections 4 are arranged along the sides of the polyhedral surface of the cap 11. Pulling the clamps 6, the lower rotator 1 head 11, thereby "fork" the tabs of the cartridge cover 3 versatile wedge 11, opposite longitudinal grooves 13 are fixing rods 14 (Fig. 3) when you leave the clamps 6 they retract in grooves 13 of the cap 11.

Following the capture of the screw section 4 by means of clamps 6, realize the rise. Auger section 4 takes a vertical position as a result of the rise.

After the lift took place and screw section 4 was in a vertical position, it is lowered down on a pre-prepared horizontal platform (stand), and perform down so that the head 11 of the screw section 4 is fully inserted inside the cartridge 3 (Fig. 2). Thus the outer surface of the cap 11 must coincide with the inner surface of the cartridge 3. This facilitates the location of the retaining rods 14 within the longitudinal grooves 13 of the head 11 of the screw section 4.

Then, turning the head 20, located in the lower part of the screw section 4, kinematically linked" mechanism inside screw pipe 9 and pull about 17�odama through the head 11 and which is integral with the retaining element 16, located on the top of the head 11 of the screw sections 4, turn this locking element 16 by 90° (Fig. 4).

With the full location of the cap screw 11 section 4 within the cartridge 3 lateral projection 15 of the cap 11 is in the transverse slot of the pocket 7, and locking the rotary element 16 is inside that pocket 7, which is located in the upper part of the cavity of the cartridge 3. When rotated 90° the locking element 16 is hooked over the tabs of the pocket formed by the transverse through-groove (Fig. 4).

Thus the screw section 4 is fixed relative to the holder 3 in the axial direction. Now the cartridge 3 and the screw section 4 are integrated (Fig. 2).

Operation "crushing", i.e. "putting on" of the cartridge 3 on the cap screw 11 section 4 also perform during the drilling process, when the well is previous auger section 4 or more auger sections 4 and want to increase the length of the column due to the additionally attached auger section 4. In this case, the screw section 4, fastened to the cartridge 3, is lowered to the previous auger section 4, located in the well. Connection previous auger section 4-added a screw section 4 is performed by turning the top of the head on the lateral surface of the previous auger section 4. Before connecting pre-perform pixelydimension auger section 4 of the cartridge 3, as already mentioned, the lower rotary head 20 added auger section 4.

If necessary, increase the depth of the well, the pillar of the screw sections 4 left in the borehole so that the upper side of the rotary head 19 of the last auger section was above ground level easy height, then it is rotated by the rotation of the fixing element 16 on the cap screw 11 of section 4, being within the cartridge 3, and by pulling the locking rods 14 of the longitudinal grooves of the tip, perform the disengagement of the cartridge 3 and the screw section 4.

The cartridge 3 is detached from the screw section 4, and can perform extension of the next auger section 4 (procedure) the method described above.

Reducing auger post by disconnecting auger sections 4 operates in reverse order.

After lifting screw of the pole above ground level so that the upper swivel head penultimate section was at an accessible height, a special plug fix screw post relatively well, which keeps it from falling into the well.

Then turn the upper head 19 penultimate section rasskazivaut last and penultimate auger section 4.

After disconnection, propustiv device for rotary dip section of the working tools�NTA in the ground with detached auger section 4, by turning the bottom of the rotary head 20 is rotated the locking element 16 and raskreplyayut auger section 4 and the cartridge 3. Auger section 4 remains hanging in the cartridge 3 through the locking rods 14, which are located in the longitudinal grooves 13 of the cap 11.

Rotator 1 with gear 2 and the cartridge 3 is lowered to the ground, ensuring that the screw section 4 laid down, turning around the locking rods 14, and was in a horizontal position (Fig. 1). Now the retaining rods 14 on the cartridge 3 in the immediate proximity, and you can remove the Chuck screw 3 from section 4.

In the future, the cartridge 3 is connected to a screw section 4, which extends above the hole, remove the plug supporting pillar of the screw sections 4 and repeat the procedure to reduce it, disconnecting sequentially, section by section.

All operations on the connection (capacity) of sections of the working tool (screw piles or auger sections ) 4 are performed on the ground without climbing the height, without any additional ladders or scaffolding.

Thus, the claimed device provides a reliable and safe immersion of the working tool (screw section) in the soils without axial movement relative to the cartridge, thereby expanding their technological capabilities.

Operation, connection and disconnection of sections of the work�his instrument is fast and does not require holding them in an upright position.

In addition, the inventive device allows for the possible lifting of the section of the working tool from the ground or from a vehicle and for reducing the time of the fixing section of the working tool in the Chuck rotator to significantly improve the performance of works on preparation to the rotational dip sections of the working tool into the soil, and improve conditions of work, as all the work is not done at altitude and on the ground, in the vicinity of the place of execution.

FIELD: drilling equipment, particularly adapted to use in bottomhole assembly to reduce deviation of holes bored in anizotropic rock.

SUBSTANCE: drill pipe comprises metal body having ring-shaped cross-section with two diametrically remote segments forming flat longitudinal areas on pipe surface. Drill pipe also has connection threads located at body ends. In the first embodiment outer layers of flat longitudinal areas are formed of metal having higher coefficient of elasticity than that of metal used for remainder pipe body forming due to plastic deforming thereof. In the second embodiment outer layers of flat longitudinal areas are coated with metal having higher coefficient of elasticity in comparison with that of basic metal. In the most preferable embodiment metal layer is applied on plastically deformed metal of flat longitudinal areas to provide unequal rigidity along main axes of pipe cross-section.

EFFECT: increased efficiency and improved operational performance.
