The device comprises a housing 1 suspended on a cable 2 by means of a block 3 to an earring 4. A pipeline 5 is connected to the upper part of the housing 1, connected to peripheral pipelines 6 and 7 located at

by destroying the rock with cutters 31 and removing it according to TP 5 from the section of the trench. In order to lift the rock, compressed air is supplied through pipe 12. Pulp suction is carried out by means of a retractable TP 9 port. 1D Il.

the front and rear walls of the housing 1, the pipeline 8 connected to the telescopic part of the central pipeline 9 equipped with a drive 10 made, for example, in the form of a hydraulic cylinder, two oil lines 11 and a pipe 12 for supplying compressed air connected to the air distributor 13. The air distributor 15 is connected to the pipeline 8 by means of a pipe 14, and through pipes 15 with peripheral pipelines 7. In the lower part of the casing 1 there is located a diaphragm 16 with axes 17 located in it, on which the carrier is rotated 18. The turn of the carrier 18 is carried out by hydraulic cylinders 19, the rods 20 of which are in contact with the bolts 21 attached to the ledges 18. In the hollow axles 17 the shafts 22 with sprockets 23 driven by chains 24 from the asterisks 25 hydraulic motors are rotatably mounted 26. The shafts 22 are equipped with sprockets 27 at the ends, leading chains 28, equipped with porous teeth 29. In the lower part of the carrier 18, cutters 31 are located on the shafts 30, equipped with porous teeth. Sprockets 32, driving cutters 31 are placed at the ends. The hydraulic cylinders 10 and 19 of the drives of the telescopic part of the central pipeline 9 and the carrier 18 are connected to the oil pipes 11 via one-way delay units 33. The device has a block of reverse cutters 31, drove 18 and pipeline 9.

The device is suspended by a cable 2 via a cable 2, its pipes 5 and 8, the oil pipes 11 and the tube 12 are connected to the corresponding devices of the surface equipment 34, the spool 35 of the surface equipment 34 is installed in the right position, corresponding to

15

The top-down mode, from the surface equipment 34, is supplied with compressed air, oil, and mud, as well as receiving and cleaning of the pulp from the device. With a given direction of oil movement, the piston 36 of the distributor 37 moves in the housing 38 to the left and opens the compressed air supply to the pipeline 8 of the central pipeline 39, the telescopic part of the central pipeline 9 is in its highest position due to the movement of the hydraulic cylinder 10 to the upper position. Blocks 33 one-way delays, consisting of parallel-connected throttles 41 and non-return valve 42, ensure unobstructed draining of oil from the cylinder cavity and strictly regulating The oil flow into the cavity is provided, which ensures that the actuators of hydraulic cylinders 10 and 19 of the telescopic central pipeline 9 and carrier 18 are strictly triggered. The peripheral pipeline 43 provides the supply of mud from pipeline 6 to the fresh ends of the peripheral pipeline 7. Rods of hydraulic actuator cylinders 19 are 44 in the extended state, thereby ensuring the operation of the cutters 31 in the clear state. The cutter drive 45 provides the direction of rotation of the hydraulic motors 26 and cutters 31 in such a way as to facilitate the supply of the destroyed rock to the central pipeline 9, which in the mode runs from top to bottom.

When switching to the bottom-up mode of operation, the supply of the clay solution to the pipeline 6 is stopped and the spool 35 of the surface equipment 34 is shifted to the left position, as a result of which the flow direction

Reverse is reversed. As a result, the piston 36 of the air distributor 37 moves to the right, opening the supply of compressed air to the lower ends of the peripheral pipeline 43. The shaft 40 of the actuator 10 of the central pipeline with the drive 39 moves down, moving the telescopic center pipe 9 to the lower position. embedded in

the cylinders 19 are in position, in which the carrier 18 is rotated and the milling cutters 31 placed at their ends are moved apart. The hydraulic motors 26 of the milling cutter 45 change the rotational direction to the opposite, resulting in the reverse direction of rotation of the milling cutters 31, driven by sprockets 27 and chains 28, resulting in more favorable conditions for supplying the broken rock to the peripheral pipelines 7. The filler is fed through a central pipeline 8,

The throttles 41 by the one-way delay unit 33 are adjusted so that they ensure the following operations to be carried out sequentially: when switching from top-down mode to bottom-up mode and filling, first change the direction of rotation of the mills 31, then expand them to the sides, and then lower the telescopic center pipe 9, when reverse switching spool 35, first lift the central telescopic pipe 9, and then the approach of the cutters 3 I.

The construction of a wall in the ground is carried out by demolishing the rock 46 with the machine cutters 31 and removing it through the pipeline 5 from the trench section 47 together with the solution 48 filling the trench section 47 to ensure the stability of its walls. In order to lift the rock, compressed air is supplied to the device through the tube 12. The pulp 49 is sucked in by means of a retractable pipe of the pipe 9, which is in the retracted position. The clay solution 48 is fed through conduit 5 and enters trench section 47 through peripheral pipelines 7. The direction of rotation of the mills 31 provides pulp 49 to the central telescopic pipe 9. As the rock 46 is destroyed, the device is lowered.

When the device reaches the set mark, a change is made in the direction of rotation of the milling cutters 31 by turning the pulp to the peripheral pipelines 6 and 7, diluting the milling cutters 31, and the lifting of the device begins.

At the same time, the compressed air supplied through the tube 12 is switched to the peripheral pipelines 6 and 7. As the device 1 rises, the central telescopic pipe 9 moves out. When it reaches the lowest position along the pipe 8, aggregate 50, Solution 48 begins to be supplied to section 47 of the trench. in order to ensure the stability of the walls of the trench section 47, it is fed by a spruce from above. When penetrating section 47 between it and the previous filled section, a separation pillar is left, the length of which is, for example, 0.4 of the total amount of extension of section 47 of the trench.

Each subsequent section 47 of the trench is filled similarly to the first section from the bottom up, 31 the section 47 of the trench is lengthened, and filler 50 is fed through the extended telescopic pipe 9. At the same time, one of the mills 31 removes the separator A from the top to bottom.
