Description

 The invention relates to mining equipment, and in particular to sinking mechanisms that can be used for laying vertical shafts of mines to a greater depth.

 From the patent of the Russian Federation N 2001277 C1, cl. E 21 D 1/06, publ. 10.15.93 there is a known method of drilling large diameter wells, including the simultaneous drilling of a leading well with a pilot bit mounted on a double column with a screw conveyor, and its expansion with the formation of a conical face at the expansion site. To reduce energy consumption and efficient dust suppression, water is supplied to the bottom of the expansion section of the well without reverse circulation. The cleaning agent is fed through the double-pipe annular rope, and the sludge from the bottom of the leading well and the bottom of the expansion section is fed by auger transport into the loading windows of the double column with subsequent removal through its central channel.

 The disadvantage of this method of drilling is that it has a limited diameter for drilling the well and its depth, the removal of sludge from the bottom is carried out by means of a screw conveyor.

 From A.S. USSR N 137865, class E 21 D 1/06, publ. 08/18/61 known device for drilling vertical shafts of mines, equipped with a differential milling-crushing executive body with split rods, receiving rotation from two independent drives with an adjustable speed with the ability to destroy the rocks of the face by milling and crushing, depending on the strength. The device is equipped with a paver consisting of radial jacks, a face press and a rotating formwork, the use of which will automatically erect a permanent lining on a single-starting spiral from press-cast concrete. For automatic control of the vertical drilling of the barrel, the device is equipped with two level switches located crosswise on the drill string.

 The disadvantage of this method of drilling is that for the destruction of the rock face establish a differential milling-crushing working body, moving in a spiral with simultaneous horizontal pressing of concrete, and there is no reinforcement of the walls of the barrel and not waterproofing the outer wall of the shaft of the mine.

 The problem to which the invention is directed, is to provide continuous laying of vertical shafts of mines to great depths while laying reinforcement, strengthening the walls of the shaft of the mine and its waterproofing.

 To solve the problem in a device for laying vertical mine shafts, including a cylindrical body having hydraulic cylinders of movement located along the diameter, and a ground development tool installed in the lower part of the formwork, having an axial feed and a rotation drive, as well as means for removing soil and feeding concrete, hydraulic cylinders of movement are installed with the possibility of supporting their rods on the soil of the developed base and are equipped with hydraulic cylinders for tearing the formwork from the hardened concrete, means For concrete supply and soil removal, it is made in the form of an elevator, the soil development tool is made in the form of a conical cutter with an inner diameter for filling the soil with an axial feed pipe with an axial feed hydraulic cylinder, the saddle part of which is mounted for rotation on a support having a rotation mechanism, while there is a device with a roller slewing disk for laying reinforcement and winding reinforced wire on it and a pipe for supplying waterproofing to the outgoing reinforced concrete pipe.

The invention is illustrated by drawings, where
in FIG. 1, 2 shows a General view of the housing, a longitudinal and cross section,
in FIG. 3 - working body for soil development;
in FIG. 4 - mechanism for winding reinforced wire on reinforcement;
in FIG. 5 - conical cutter;
in FIG. 6 is the same, a section along AA in FIG. 5.

 A device for laying vertical shafts contains a cylindrical body 1. In the lower part of the cylindrical body 1, a soil preparation device is installed, made in the form of a cone cutter with a drive mechanism and a soil receiver 3 and an internal screw 4 with a drive mechanism 7 for filling the soil receiver with developed soil. The working body moves axially by hydraulic cylinders 6 and is mounted in the saddle part 8 having a rotation mechanism 9. The device also includes supports 10, a rotation mechanism 11 of the support 10, a rotating support 12 with a rotation mechanism 13, a fixed support 14, hydraulic cylinders 15 for tearing the device from solidified concrete, a roller slewing disk 16 for laying reinforcement 18 in the holes and for installing coils with reinforced wire 17 on it and winding it onto the reinforcement 18 through a stationary roller 24, the drive mechanism 19 of the roller slewing ring disc 16, hydraulic cylinders 20 for moving the device in a vertical plane, a lift 21 for removal of soil feeding reinforced wire reinforcement lifting and lowering persons. Reception hatch 25 for filling reinforced space with concrete 22. To prevent concrete from entering the roller slewing ring, rubber covers 23. There is also a workstation for operators 26 and a pipe 27 for supplying the waterproofing mixture.

 The device operates as follows.

 A device having a cylindrical body moves vertically with the help of hydraulic cylinders installed uniformly in diameter of the body. In the lower part of the casing, a working body for soil development is installed, which is made in the form of a cone cutter with a double drive mounted on a pipe with an internal screw for filling the pipe with developed soil, and having axial movement of the working body to any point on the lower part of the mine shaft development. The development of the soil under the support is carried out when this support retracts the rod and the device stands on five supports, and the mill at this moment selects the soil under the support. When the cutter rotates, the developed soil enters the pipe and fills it with the help of a screw. Pipe filling is controlled through control windows. The working body turns to the elevator and, rotating in the opposite direction, pours soil through the cutter into the elevator. The elevator takes the developed soil out of the shaft to the surface.

 Strengthening the walls of the shaft of the shaft is achieved by the fact that the concrete is fed into the space between the casing and the outlet pipe with the elevator while laying the reinforcement and winding the reinforced wire onto the reinforcement.

 The waterproofing of the outgoing reinforced concrete pipe is achieved by the fact that a waterproofing mixture is supplied through the pipeline, which is pumped into the space between the outgoing reinforced concrete pipe and the wall of the casing.

 To obtain a reinforced concrete pipe of a vertical shaft of a mine shaft covered with waterproofing, concrete is fed into the reinforced space 22 from the elevator 21 through a receiving hatch 25. The hydraulic cylinder rods are retracted, and the hydraulic cylinder rods 20 are supported on the ground of the developed base. The vertical movement of the device occurs as a result of the fact that the hydraulic cylinders 15 detach the device from the hardened concrete, and the hydraulic cylinders 20 retract the rods, forming a new reinforced void 22 to fill it with concrete.

 With the vertical movement of the device, the reinforced wire 17 is wound on the reinforcement 18 through the roller 24 with a roller slewing disk 16.

 In order to cover the exit reinforced concrete pipe with insulation, the waterproofing mixture is pumped through the pipe 27 and through nozzles located uniformly over the entire diameter of the exit reinforced concrete pipe.
