The invention relates to mining and construction, in particular to equipment for trenchless laying of pipes under roads and other engineering structures.

Known supporting device for puncture horizontal wells containing a tubular frame, front and rear base plate connected with the frame and supported on the wall of the pit, power equipment in the form of the block of cylinders and the device operation control when the piercing hole (see USSR author's certificate No. 242057, E 02 F 5/18, 1967).

The disadvantages of this device are difficulties in installation, design complexity and noncompact its location, which increases the size of the pit, the dimensions of the equipment and makes its storage and transportation.

Known installation comprising a power cylinder with a supporting frame, placed in the pit and supported on the ground of the pit thrust plate (see patent of Russia №1518462, E 02 F 5/18, 1987).

The disadvantages of this setup are larger support frames and plates, to reduce the load on the ground, however, this circumstance complicates the Assembly, disassembly, transportation and storage installation.

Known adopted as a prototype supporting device for horizontal perforation of wells containing placed in the pit resistant wall to communicate with power equipment and GRU is the fact (see USSR author's certificate No. 876877, E 02 F 5/18, publ. 30.10.1981).

However, in this device, the force developed by the hydraulic cylinder to pierce or extension wells, soil perceives through the thrust wall and require large dimensions of the pit and wall to reduce the load on the ground, which complicates the Assembly, disassembly, transportation and storage of the device.

The technical result of the present invention is to create such a support device for horizontal perforation of wells, which reduces the load on the soil, reduces the dimensions of the supports, which reduces the cost of installation, dismantling and transportation of the device, creates the necessary conditions for its storage and warehousing.

The essence of the invention as a technical solution is expressed in all of the following essential attributes.

Supporting device for horizontal perforation of wells contains placed in the pit resistant wall, interacting with power equipment and soil.

Resistant wall is made in the form of a mobile container, dimensions and material which ensure preventing its collapse upon contact with the ground, the container consists of a bottom with technological hole, vertical cylindrical wall with cargo hooks and swivel lid inside the container includes cardio equipment and operator's workstation, and in the lower lateral parts of the container are located warehouse capacity.

Figure 1 presents the scheme of the container in vertical section, figure 2 is a transverse horizontal section a-A.

The support device is made in the form of a mobile container 1, the dimensions and the material of which provide preventing its collapse upon contact with the ground, while mobile container 1 comprises a bottom 2 with the technological hole 3, a vertical cylindrical wall 4 cargo hooks 5 and a hinged cover 6, inside mobile container 1 installed power equipment 7 and the operator's workstation 8, and the lower lateral parts of the mobile container 1 is placed storage container 9. In addition, inside the mobile container 1 has a control knob 10, the remote control 11 and step 12. The supporting device operates as follows. When performing horizontal well drilling or puncture mobile container 1 is vertically lowered into a pit on the ground (not shown)to the hydraulic power equipment 7 down pressure oil from a pumping station (not shown) and start a hole in the ground. Resulting reactive force from a puncture or drilling through the bottom 2 and a vertical cylindrical wall 4 is perceived by the soil. The surface of the ground contact is created of sufficient size, cobine cause smati and collapses to the ground, and material travelling container 1 (for example, steel) is not deformed. With increasing well depth necessary compartments boom operator takes from the storage tank 9. When extending the wells of these tanks are extenders and other necessary equipment (not shown). Management of drilling, the operator carries out by means of the control stick 10 and the remote control 11. To skip from the mobile container 1 or back bars and extenders technological hole 3, which for its size covers the bottom 2 and a vertical cylindrical wall 4 of the mobile container 1.

After completion of the work required property is placed in a storage container 9, and a movable container 1 by means of the cargo hooks 5 are removed from the pit and transported to the next job when closed, the lid 6, which ensures the integrity and security of property.

The supporting device is manufactured, successfully tested and applied in NGO ekoprom Ltd. in the manufacture of the pilot wells and their expansion, and also during drilling. In addition, it can be used when replacing old pipelines on new and cabling, as well as the workplace of the operator and the capacity for warehousing, storage and transportation process equipment.

The supporting devices is for horizontal perforation of wells, containing placed in the pit resistant wall to communicate with the power equipment and the ground, wherein the thrust wall is made in the form of a mobile container, dimensions and material which ensure preventing its collapse upon contact with the ground, while mobile container consists of a bottom with technological hole, vertical cylindrical wall with cargo hooks and swivel lid, inside mobile container power equipment and operator's workstation, and the lower lateral parts of the mobile container placed storage containers.
