Production method of excavation and laying works at routing of underwater pipelines, and device for its implementation

FIELD: machine building.

SUBSTANCE: pipeline is mounted on a deck of a pipe laying ship and laid at the water reservoir bottom. A column of two machines moves along the pipeline: a pipe burying barge and a trench burying machine at some distance from each other, which is technologically substantiated, but not more than 100 metres. The pipe burying barge excavates a trench immediately under the pipeline and lays the developed ground into accurately shaped dumps on both sides; the pipeline is lowered into the trench under action of dead weight. The trench burying machine displaces the formed dumps into the trench and covers the laid pipeline with the ground earlier extracted from under it. Machines operate in an automatic mode, remotely controlled and provided with energy along cables hung on floats from an underwater or surface basic ship. The pipe burying barge is made in the form of two working elements of a back-acting shovel, which are mirror-like located relative to each other and each of which has the possibility of being turned in a horizontal plane and laterally inclined by means of horizontal and inclined hinges. Reactive forces of the working elements are closed on a common frame and not transmitted to a travelling gear.

EFFECT: improving efficiency and reducing costs at performance of works.

The invention relates to the field of construction of submarine pipeline systems during the development of oil and gas resources of the shelf zone of the world ocean, and with the laying of pipelines on the bottom of the other reservoirs.

A known method of laying pipes along the bottom of water bodies, which consists in the development of underwater trenches dredge, followed by the laying of the pipeline by means of a ship-booms and backfilling it imported soil (V. Minaev "Machines for the construction of trunk pipelines" ed. "Nedra M. 1973 str-377; str-414). The dimensions of excavated dredge trench is very significant, due to the guarantee of the ingress pipeline when the standpipe with the pipe-laying vessel and opposition to samwu trench undercurrent in the time interval from the moment of its opening until pipe laying on her bottom. The large size of the cross section of the trench also require significant amounts of imported soil for backfill, which significantly increases the overall cost of the work, even if not to take into account the use of very expensive equipment.

There is also known a method of laying a pipeline on the bottom of the reservoir, in which the vessel is pipelayer mounts on my deck piping from individual tubes and gently lowering, puts it n the bottom of the reservoir, and then underwater robosapien, moving along it, throws directly under the pipeline trench in which he falls under its own weight (Veenai "Machines for the construction of trunk pipelines" ed. "Nedra M. 1973 str-403).

The application of this technology allows to increase the rate of production work and ensures precise placement of the pipeline in the trench.

When the depth of the pipeline of the same length and diameter at the same depth under other equal conditions robosapien must remove the soil several times smaller than the dredger. In addition, it can operate at great depths.

There are various designs of underwater trubozagotovitelniy implementing this method. They get energy from the base of the vessel located on the surface. Spread trubozagotovitel with suction and jetting the working bodies and their combination, and in the case of solid ground, with milling and chain rippers (VI Minaev "Machines for the construction of trunk pipelines" ed. "Nedra M. 1973 str-403). In all known trubozagotovitelnyj used hidromasazu developed ground using suction or hydroelectric devices with discharge his or suction in the holds special barges, h is ordinary then export it in a special place or use then for underwater backfill the trench (VI Minaev "Machines for the construction of trunk pipelines" ed. "Nedra M. 1973 str-396). But the majority of the developed soil still is lost. All these operations significantly increase the cost and require bringing additional volumes of soil to backfill the trench after laying of the pipeline.

In order to eliminate the disadvantages of the known methods of excavation and paving works, thus increasing their efficiency, and to provide the ability to produce work at great depths with minimal cost, we propose a new method of their implementation.

The claimed method of manufacturing earthmoving and paving works for laying underwater pipelines aimed at the creation of such technology, which would not be necessary in imported soil for backfill underwater trench due to the fact that it underwater robosapien using only mechanical method of trench excavation without creating powerful local satirically flow created by suction and jetting the working bodies of the above trubozagotovitelniy, gently puts extracted from under the pipeline soil in two of the blade on both sides of the underwater trench, and moving on technologically reasonable distance of underwater Trubodetal is also gently pushes these dumps back into the trench, falling asleep already fallen to the bottom of the trench the pipeline. Closing the resulting reactive efforts on its frame and not passing them thus to their travel gear, in order not to lose patency in terms silty bottom surface. Both underwater machine controlled and sustained energy through cables with the base surface of the vessel type when opening the water or underwater type in the conditions of continuous ice cover.

The problem is solved due to the fact that in the method of manufacturing earthmoving and paving works for laying underwater pipelines, according to which the pipe is mounted on the deck of a ship-booms and lay on the bottom of the reservoir, tear trench directly under the pipe and lower pipe into trench formed under the action of its own weight, the passage of the trench is performed by moving columns of two undersea machines: submarine trubozagotovitel and underwater Trubodetal that operate in the automatic mode, remotely controlled and sustained energy posted on floats cables from the base ship, found in underwater or above-water position, while underwater robosapien lifts under the pipeline trench and lays developed soil in neatly formed dumps on both sides,and the underwater Trubodetal moved on technologically reasonable distance for underwater trubozagotovitel, but not more than 100 meters, and underwater Trubodetal shifts educated underwater trubozagotovitel dumps into the trench and laid asleep pipeline early extracted from under the ground.

In addition, the problem is solved due to the fact that the chassis base of a vessel provided with an air bell and for periodic replacement of the cutting tool working bodies underwater trubozagotovitel carry out the move of its working bodies in a vertical position and placing them in the inner space of the air bell base of the vessel, thus carry out the descent of the base of the vessel to hang it over the underwater trubozagotovitel or climb the latter to the base of the vessel, and the underlying vessel is placed over underwater trubozagotovitel depth, guaranteeing safe operation staff base ship inside his air bells. When working on small depths rise underwater trubozagotovitel can be implemented with the release of its working bodies to the surface.

In addition, the problem is solved due to the fact that from time to time are nourishing the energy base of the vessel from the submarine to recharge its batteries using remotely operated and automatically connect to each other connecting devices, while od is about of docking devices is a foster and raise the base of the vessel together with the cable-rope, and the other connecting device is feeding, its down with the submarine together with cable trescom towards receiving a docking fixture.

In addition, the problem is solved due to the fact that both underwater machine when used stacked pipeline as the main programming element and in direct contact with them by means of bounding and guiding devices with sensors for fixing the spatial position of the pipeline and working bodies of underwater vehicles with regard to him.

The problem is solved due to the fact that underwater robosapien, which includes body, chassis and attachments for excavation, characterized in that the working bodies for excavation made in the form of two mirror located to each other working bodies of the universal shovel excavator type "backhoe", each of which is located on the housing and installed separately from each other rotate in a horizontal plane by means of a vertical hinge mounted on the case, and with the possibility of lateral tilt in the vertical plane, with an additional hinge for pivoting of the vertical hinge axis which is located in the plane of motion of the OS is ESD mechanisms working body "backhoe".

In addition, the problem is solved due to the fact that each working body is installed with slope in a rotating plane relative to the vertical axis of the hinge and is inclined to it.

In addition, the problem is solved due to the fact that underwater robosapien equipped with trailer pick shield belokurogo type, made in the form of curly dozer blade with sides to protect the bottom and side surfaces of the pipeline from accidental contact with the working bodies.

In addition, the problem is solved due to the fact that trailed pick the shield connected to the housing of the underwater trubozagotovitel through hard thrust with articulated joints that are installed with the possibility of rotation in two mutually perpendicular planes to avoid blockages pick shield on one side.

In addition, the problem is solved due to the fact that the cowling trailer pick shield made with supporting rollers, equipped with the elastic tire for engagement with the upper and lower parts of the surface of pipeline laid.

In addition, the problem is solved due to the fact that the supporting rollers trailer pick shield hinged to the body shell by Centerpoint rocker.

Furthermore, we have for the ache solved by the hull of the submarine trubozagotovitel connected with a hard thrust trailer pick of the shield by means of a remotely controlled detachable device.

In addition, the problem is solved due to the fact that the body is made with two ballast tanks, which are located on its sides and have a device for blowing them with compressed air.

The invention is illustrated by drawings, where figure 1 shows a diagram of the production of earthmoving and paving works using basic ship in surface position; figure 2 - scheme of production of earthmoving and paving works using the base ship, which is in a submerged position; figure 3 - excerpts of the trench beneath the pipeline (front view); figure 4 - scheme of lowering the pipeline into the trench (side view); figure 5 - connection node of the hull underwater trubozagotovitel with pick shield; figure 6 is a section along a-a in figure 5; figure 7 - diagram of the backfill soil pipe; Fig diagram replacement of the cutting tool working bodies underwater trubozagotovitel during the descent of the base of the vessel; figure 9 is the same when lifting underwater trubozagotovitel; figure 10 is an example of the constructive execution of the connection node of the working body with trubozagotovitel and figure 11 is another variation of the structural embodiment of knots the connection of the working body with underwater trubozagotovitel.

In accordance with the method of manufacture of earthmoving and paving works for laying underwater pipelines on deck-booms mounted pipe 1 and using, for example, the lifting mechanism (not shown)located on the ship-steering, stack it on the bottom of the reservoir on the design axis. Then tear off a trench directly under the pipe 1, in which the lower pipe 1 under the action of its own weight. The passage of the trench beneath the pipeline 1 is performed by moving along the bottom of the reservoir columns of two undersea machines: submarine trubozagotovitel 2 and underwater Trubodetal 3, respectively, for the passages of the trench and laying of the pipeline 1 and for backfilling the pipeline trench 1 soil, which operate in automatic mode. Underwater machines 2 and 3 remotely controlled and sustained energy through cables 4 from the base ship. As the base of the vessel can be used surface vessel 5 (Fig 1) or underwater vessel 6 (figure 2). Underwater machines 2 and 3 have increased maneuverability and agility in terms of silty sediment that ensures compliance with the transfer mechanism, for example, in the form of a rotary screw (auger) propulsion. Underwater robosapien 2 lifts under the pipeline trench 1 AC brings the I and the required depth, copying the longitudinal profile of the pipeline 1, regardless of the elevation of the bottom of the reservoir. While underwater robosapien 2 at the same time puts the developed soil in neatly formed dumps 7 located on both sides of the trench (figure 3). Saped using scuba trubozagotovitel 2 pipeline 1 gently lowered into the trench under the action of its own weight. Underwater Trubodetal 3 shifts educated underwater trubozagotovitel 2 dumps 7 in the trench and laid asleep pipeline 1 previously extracted from under the ground. Underwater Trubodetal 3 is moved on technologically reasonable distance for underwater trubozagotovitel 2. The distance between the two underwater vehicles 2 and 3 is selected depending on the stiffness characteristics of the stacked tubing 1 and the depth of the trench. It should be noted that in all cases the specified length does not exceed 100 meters, that allows to manage both underwater machines 2 and 3 with one base ship 5 or 6. With this remote control and energy supply for underwater vehicles 2 and 3 is carried out by hanging, respectively, control and power cables 4 on the floats 8, which prevents an accidental hit in the zone of action of the working bodies of underwater vehicles 2 and 3 and laid under Truboprovod 1 (figure 1).

Base ship 5 or 6, which is provided by the power supply, coordination and remote control of underwater vehicles 2 and 3, can be fitted with a lifting mechanism for lifting to the surface and sinking to the bottom of the pond underwater vehicles 2 and 3 (Fig. not shown) for periodic replacement of the cutting tool of their working bodies. In cases where the pipeline 1 is at great depths or in conditions of ice cover, as the base of the vessel, preferably using a self-propelled underwater vessel 6 catamaran base type, which is equipped with an air bell 9. Air bell 9 is made so that the inside part of it could enter the working bodies of the underwater trubozagotovitel 2 for periodic replacement equipping them cutting tool as it is wear and tear. To perform the specified operation underwater robosapien 2 stop and cease work on the passage of the trench. Then move the working bodies of the underwater trubozagotovitel 2 up to a vertical position. When this exercise maneuvering and descent of the base of the vessel 6 to hang it over the underwater trubozagotovitel 2. It should be noted that the descent and ascent of the base of the vessel 6 may be implemented, for example, by injection of water or air in his Ballas the main tank 10 to change its buoyancy. Then take further descent of the base of the vessel 6 and place the working bodies of the underwater trubozagotovitel 2 in the inner space of the air bell 9 base ship 6 (Fig). Partial entry of the working bodies of the underwater trubozagotovitel 2 in air bell 9 of the base of the vessel 6 to enable maintenance personnel to the base of the vessel 6 to replace the worn cutting tool with a new one. After the above replacement base vessel 6 by blowing compressed air into the ballast tank 10 is moved in a technologically informed position. In those cases, when working underwater trubozagotovitel 2 is carried out at great depths, at which the lowering of the base of the vessel 6 is unsafe for operation in the air bell 9 staff, basic vessel 6 is placed over underwater trubozagotovitel 2 at a safe depth. While underwater robosapien 2 disconnect from the pick of the shield 11 and up to the base of the vessel 6 by blowing its ballast tanks 12 compressed air (Fig.9). After working on the replacement of worn cutting tool working bodies underwater trubozagotovitel 2 in its ballast tanks 12 let the water and change thus its buoyancy. Under the influence of gravity underwater robosapien 2 is lowered on the tubing 1, where it is United by to pick shield 11, and continue to work on digging the trench for the pipeline 1. One of the options for the implementation of the technology the rise of the underwater trubozagotovitel 2 to the base of the vessel 6 and reverse its descent to the pipeline 1 can be implemented using lifting devices placed on the base Board (the drawings are not depicted).

According to the proposed technology there are two possible structural embodiment of the base of the vessel 6. One of the basic vessel 6 has its own independent source of energy, for example, a nuclear reactor. The second option involves the implementation of the basic vessel 6 with rechargeable batteries that are in the process periodically recharged from the power plant of the submarine 13 using two controlled expansion devices. One of the docking fixtures 14 is a foster and his raise on the cable Crosse with the base of the vessel 6. The second connecting device is supplying 15 and its loose on the cable Crosse from a submarine 13 towards receiving a docking fixture 14 (figure 2). Receiving a docking fixture 14 may be performed, for example, in the form of a buoy with navigation system, alarm and equipped with pin lock camera for a tight connection with the supply connecting device 15. Supply docking lighting is of 15 remotely controlled submarine 13 cable 4 and can be equipped with feeding screw, ailerons and ballast tanks, blown air hoses from a submarine. Supply connecting device 15 can be equipped with television cameras, spotlights and a receiver receiving the signal generator is placed on the receiving docking device. On the supply connecting device 15 can be placed gripping device, which is installed with the possibility of interaction with the corresponding locking device which is placed on the receiving docking fixture 14.

Both underwater machines 2 and 3 move along the pipeline 1 and used in their work laid the pipe 1 as the primary programming element. Underwater robosapien 2 and underwater Trubodetal 3 are in contact with the stacked pipe 1 using bounding and guiding devices, which are equipped with sensors for fixing the spatial position of the pipeline 1 and the working bodies of underwater vehicles 2 and 3 relative to the stacked tubing 1. The signals of these sensors is converted in software systems machines at the command signals, which are transmitted on the control elements of hydraulic systems for underwater vehicles 2 and 3. Using the command signals are adjusted accordingly t is actorii and speed underwater vehicles 2 and 3 relative to the stacked tubing 1, as well as develop depth of the trench and the width of ground dumps.

Underwater robosapien 2 includes a housing 16 mounted on the chassis 17. Suspension 17 can be performed, for example, in the form of caterpillar trucks or wheels. The preferred option is a constructive execution of the chassis 17 in the form of four parallel spaced rotary-screw propulsion, the direction of winding of the spiral lugs each of which is opposite to the direction of winding adjacent. This design driving mechanism 17 provides reliable moving underwater trubozagotovitel on the muddy bottom surface of the reservoir, and freedom of maneuver and high tractive effort. On the housing 16 of the underwater trubozagotovitel are working bodies for excavation, which are made in the form of two mirror located to each other working bodies of the universal shovel excavator type "backhoe". Each working body contains pivotally interconnected by a bolt 18,the handle 19, and the bucket 20, and a power cylinder for rotating them relative to each other. The power cylinder can be performed, for example, in the form of a hydraulic cylinder. Each working body is installed on the housing 16 to separate from each other (independent) rotation gorizontalnoi plane. For this purpose, the bolt 18 of each of the working body by hinge 21 is connected to the housing 16 and has the power cylinder 22 to rotate the work of the authority in the specified plane. Each working body is installed with a lateral tilt in the vertical plane. To ensure the specified move the arrow 18 of each of the working body is installed on the rotating part 23 of the vertical hinge 21 and has the power cylinder 24 to move the work of the authority in the specified plane. When this pivoting portion 23 is connected with a vertical hinge 21 by means of additional hinge 25. It should be noted that the horizontal axis of the hinge 25 and the vertical hinge 21 are located in the plane of motion of the basic mechanisms of the working body "backhoe", i.e. in the plane formed by the swivel boom 18, a handle 19, and the bucket 20 (figure 10).

One of the options for structural embodiment provides that each working body can be mounted tiltable in a rotating plane relative to the vertical axis of the hinge 21 and is inclined to it (11). That is, each working body of the underwater trubozagotovitel installed with the possibility of rotation in the plane formed by the swivel boom 18, a handle 19, and the above 20, and the longitudinal axis of the additional hinge 25 is located at an acute angle to the longitudinal axis of the hinge 21. Constructive progress of the working bodies of the underwater trubozagotovitel allows you to easily change the geometric parameters of the trench, and to use it in a wide range of soils developed.

Underwater robosapien equipped with trailer pick shield 11 belokurogo type, which is made in the form of shaped bulldozer blade with a drum 26, which is designed to protect the bottom and side surfaces of the pipeline 1 from accidental contact with the working bodies. Pick the shield 11 is designed for selection from the bottom of the trench soil remaining after working bodies, as well as to support laid in a trench formed pipe 1 in a certain position, excluding its unacceptable bending.

Pick the shield 11 is connected to the housing 16 of the underwater trubozagotovitel through hard thrust 27. Rod 27 is connected to the housing 16 of the underwater trubozagotovitel using hinge joints 28, which provide the ability to rotate pick shield 11 relative to the housing 16 in two mutually perpendicular planes to avoid blockages pick of the shield 11 to the side.

Shell 26 trailer pick of the shield 11 can be performed with the support rollers is 29, equipped with elastic tyres (drawings not shown) for engagement with the upper and lower parts of the surface of pipeline laid 1.

Support rollers 29 trailer pick of the shield 11 may be hinged to the housing shell 26 through the Centerpoint of the rocker arm 30. The fee option constructive perform underwater trubozagotovitel provides uniform load distribution on the stacked pipe 1 from its contact surface with the support rollers 29.

The housing 16 of the underwater trubozagotovitel can be connected with a thrust of 27 trailer pick of the shield 11 using a remotely controlled detachable device which may be performed, for example, in the form of a beam 31 of the T-shaped form. Yoke 31 is installed with the possibility of interaction with the Kryukov grip 32. To actuate the hook grip 32 on a bracket 33 of the housing 16 of the underwater trubozagotovitel is the power cylinder 34 (6).

The housing 16 of the underwater trubozagotovitel can be performed with two ballast tanks 12, which are located on its sides and have a device for blowing them with compressed air (in the drawings are not depicted).

Underwater robosapien works as follows.

Previously using buckets 20 of the working bodies of the underwater rubezahl is the customer blow off a work pit, in which place pick the shield 11. Pick the shield 11 with a lever 27 connected to the housing 16 of the underwater trubozagotovitel. The housing 16 of the underwater trubozagotovitel oriented along the longitudinal axis is laid on the surface of the pipe 1, so that the longitudinal axis of symmetry of the housing 16 coincides with the longitudinal axis of symmetry of the pipe 1. The housing 16 of the underwater trubozagotovitel placed over the pipeline 1 and the chassis 17 have symmetrically relative to the longitudinal axis of the pipeline 1. With the help of buckets 20 working bodies carry out the excavation under the pipeline 1 with two sides for education under the pipeline 1 trench. Each working body of the underwater trubozagotovitel moves his bucket 20 by changing the relative position in space of the respective shafts 18 and a handle 19, that is, according to the traditional scheme of movement of the working body of the universal shovel excavator type "backhoe". Additional movement of the boom 18 of each of the working body of the underwater trubozagotovitel in the desired direction is carried out with the help of the corresponding power cylinder 22 to rotate the boom 18 and the corresponding power cylinder 24 to rotate the rotating part 23 relative to the additional fixed the and 25. The excavated soil is moved to the bucket 20 of the relevant working body of the device in the appropriate blade 7, that is, the formation of the trench beneath the pipeline 1 on its sides formed of two symmetrical blade 7. In process of formation under the pipeline 1 trench profile is set underwater robosapien using the chassis 17 is moved along the longitudinal axis of the pipeline 1. Together with the housing 16 of the underwater trubozagotovitel along the pipeline 1 is moved and connected therewith pick the shield 11. When moving underwater trubozagotovitel pick the shield 11 clears the bottom of the trench formed from the soil, which woke up from the bucket 20 working bodies. Pick the shield 11 accumulates spilled soil in the blade and moves it back into the zone of action of the working bodies that capture and remove the soil from floating blade as it accumulates. Shell 26 pick of the shield 11 protects the outer surface of pipeline laid 1 from accidental contact with buckets 20 of the working bodies of the underwater trubozagotovitel. When moving underwater trubozagotovitel along the pipeline 1 is formed below the last trench, which under the action of its own weight down the pipeline 1. It should be noted that when lowering into the trench the pipeline additional support with the help of the pick of the shield 11, which prevents the emergence in the pipeline 1 additional stresses from bending. Support rollers 29 interact when moving pick shield 11 with the outer surface of the pipe and thereby reduce the likelihood of damaging the insulation of the pipeline.

If necessary, replacement of the cutting tool buckets 20 of the working bodies of the last move in the vertical position (up) and with the help of hydraulic cylinder 34 unhooking the hook grip 32, thereby severing the casing 16 of the underwater trubozagotovitel and pick the shield 11. Then in the ballast tanks 12 underwater trubozagotovitel serves the air, thereby displacing of them liquid and providing positive buoyancy underwater trubozagotovitel. Underwater robosapien rises until the buckets 20 working bodies will not be in the air bell 9. In the air bell 9 are replacing cutting tools bucket 20 working bodies. After performing the above operations of the ballast tanks 12 let the air out, providing negative buoyancy underwater trubozagotovitel. Under the action of gravity underwater robosapien goes down, where with the help of the hydraulic cylinder 34 to return the hook grip 32 to its original position and thereby hold the chassis 16 of the underwater trubozagotovitel with pick shield the continue to work for passage of the trench and the laying of the pipeline in the manner described above.

SUBSTANCE: before repair works, a process dam is arranged downstream with the possibility to maintain water level near the middle generant of the pipeline to maintain the repaired pipeline as floating in the horizontal position. Then the soil is removed from under the pipeline, and stresses in the pipeline are maintained as close to zero as a result of water level and floating pipeline maintenance. In process of repair works they perform control inspection of design profile realisation accuracy by its measurement, if necessary, the works are carried out to remove soil or its filling. Placement onto design elevations is carried out due to reduction and complete removal of water from a trench, gradual dismantling of the process dam, arranged downstream. At the same time stresses in the pipeline, in process of repair works, vary from the initial value to zero, and from zero to the design value, which in its turn is below the initial one.

EFFECT: reduced costs.

SUBSTANCE: pipeline is mounted on a deck of a pipe laying ship and laid at the water reservoir bottom. A column of two machines moves along the pipeline: a pipe burying barge and a trench burying machine at some distance from each other, which is technologically substantiated, but not more than 100 metres. The pipe burying barge excavates a trench immediately under the pipeline and lays the developed ground into accurately shaped dumps on both sides; the pipeline is lowered into the trench under action of dead weight. The trench burying machine displaces the formed dumps into the trench and covers the laid pipeline with the ground earlier extracted from under it. Machines operate in an automatic mode, remotely controlled and provided with energy along cables hung on floats from an underwater or surface basic ship. The pipe burying barge is made in the form of two working elements of a back-acting shovel, which are mirror-like located relative to each other and each of which has the possibility of being turned in a horizontal plane and laterally inclined by means of horizontal and inclined hinges. Reactive forces of the working elements are closed on a common frame and not transmitted to a travelling gear.

EFFECT: improving efficiency and reducing costs at performance of works.

SUBSTANCE: construction method of adits containing a water-receiving element in the form of a solid unit of n number (n>2) of vertical longitudinal toe filters involves trench excavation by means of an excavating and drainage machine, laying into it of a drain pipe covered with protective filter material, and refilling of the trench by means of a padding device moving synchronously with the drainage machine and provided with a bunker for filter material with a drain chute. Laying of the drain pipe covered with protective filter material and refilling of the trench is performed simultaneously. The drain pipe covered with protective filter material is padded throughout the trench width to the depth of 15 cm above its crown from a duct to which filter material is supplied from the bunker via the drain chute. The duct represents a rectangular parallelepiped having width equal to trench width, and height that is somewhat bigger than trench depth. Duct bottom is located near the trench bottom at the distance of padding layer thickness of the drain pipe relative to the trench bottom. The duct is rigidly attached with front wall 7 to housing 8 of the excavating and drainage machine. On rear 9 wall of the duct there installed on the outer side are (n-1) vertical partition walls 10 parallel to each other and to walls 1 of the trench with a possibility of changing the distance between them according to thickness of the filters. Height of each of partition walls 10 is equal to the duct height. The filter material bunker is divided into sections by means of partition walls with a possibility of changing the distance between them and their number so that the number of bunker sections is more by one than the number of vertical longitudinal toe filters of the adit. Each bunker section is provided with its own drain chute, from which each adjacent vertical longitudinal filter is filled with heterogeneous filter material.

EFFECT: providing a possibility of filter refilling of the trench of the adit; improving hydrological action of adits and ecological and economic efficiency of draining of low-water-permeable middle and heavy loamy and clay soils.
