Abstract

WAYS OF WAYS WELLS (GROUND, including the introduction of the working body into the ground in the form of a cable along its entire length and removal of the soil, which is characterized by the fact that, in order to control the process technology, an additional working body is introduced into the ground connected to a mainstream in an infinite chain, and move it in the direction of the axis of penetration and in the direction perpendicular to it to remove and trim the soil.

Description

The invention relates to the construction of underground utilities, in particular, to the sinking of collector pipelines under structures, roads, and railway embankments. There is a known method of penetrating a well in the ground, in which the soil is punctured by means of hydraulic jacks. A conical nozzle, made from a piece of pipe in which the petals are cut, is fastened inward and welded with longitudinal joints ij, is fastened to the front end of the pipe to be pierced. The tip of the nozzle is a solid steel tip welded to it. The diameter of the outer ring of the nozzle welded behind the conical part is 16-20 mm larger than the diameter of the pipe to be pierced. The force from the jacks on the pipe to be pierced in the grooves is transmitted through a ramrod, which is a thick-walled pipe 1 m longer than the pipe from which the pipe to be pierced into the soil is welded. The diameter of the cleaning rod is smaller than the diameter of the pipe, as when piercing a pile with a pipe, the cleaning rod must be inside the latter. There are holes in the ramrod located in pairs at the distance of the rod of the jacks. The walls of shogshol around the holes are reinforced by welding of metal linings. Steel lugs are welded to the rear end of the ramrod to fasten a removable flange. At the front end of the ramrod there are two guide plates. The transfer of force from the ramrod to the pipe to be pierced into the ground is made through a steel rod with a handle that is inserted into the hole of the ramrod. As the next pipe is pierced, simultaneously with the cleaning of the rod of the jacks, the cleaning rod moves back, and the rod is moved to the next hole. In order not to damage the end of the pipe, the transfer of the force from the steel pipe to the ground through the steel flange. The flange is attached to the rear end of the ramrod tube and secured to the heads. The disadvantages of the iJToro method are high intensity and labor intensity, the puncture length is limited to 20-25 m, the possibility of using only 1-1 tl groups in homogeneous soils, large deviations from the specified direction and slope, the speed of forcing is very small. The closest in technical essence and the achieved result to the invention is a method of drilling wells in the soil, including the introduction into the soil of the working body in the form of a cable along its entire length and removal of the soil. Then, a tapered nasal is attached to the cable and pulled around it, forming a well 2. The disadvantage of this method is that for drilling wells of different diameters it is necessary to change the nozzles, and also most often it is necessary to tear off the auxiliary workings to accommodate the equipment. The purpose of the invention is to increase labor productivity and expand the technological capabilities of the installation by drilling openings of virtually any cross-sectional dimensions and configuration using one process installation. This goal is achieved by the fact that according to the method of drilling wells in the ground, including the introduction into the ground of the working body in the form of a cable along its entire length and removal of the soil, an additional working body is introduced into the ground in the form of a cable associated with the main body in an endless chain move it in the direction of the axis of penetration and in the direction perpendicular to it to remove and trim the soil. Fig. 1 shows a diagram of cutting and removing soil with a drive winch; in fig. 2 is a diagram of the vertical insertion of a branch of a cable for insertion into a penetration zone. The scheme includes an operating unit in the form of a rope 1, drums 2 and 3 of winches, guides 4 blocks, screw 5 for lowering the block, removable nozzles 6, soil 7. The method is carried out as follows. After inserting two manat threads, the entire length of the soil penetration zone 7 (anywhere in the future finished penetration hole) moves these branches along the axis of penetration in opposite directions in the form of an endless belt mounted on two drums 2 and 3 installed at opposite ends of the penetration. The movement of both threads of cable 1 is carried out in two planes: the main thing is along the axis of penetration and the auxiliary is perpendicular to it. The first movement is necessary to capture the soil and remove it from the penetration zone, and the second to cut the soil and form the desired cross-section of penetration. The branches of the steel rope 1 introduced into the driving zone are driven by a drive winch 2 and a tension block with guides 4 blocks and a screw 5 lowering the block along the guides 4. With one branch of the steel rope 1, the ground 7 is cut according to the required penetration size MiH and its configurations as well

The other branch, touching the bottom of the drift, carries the soil out of its limits. For stripping the penetration and compaction of its walls, a conical nozzle b is attached to the branch cutting the ground and pulled through the penetration.

The proposed method provides improved performance.

Labor and the expansion of the technological capabilities of the installation in terms of obtaining penetrations of virtually any configuration, cross section and size, and under any bias. It also reduces labor costs and metal consumption several times.
