The invention relates to construction equipment and can be used in trenchless laying of underground communications.

The purpose of the invention is to increase the efficiency of work due to uniform impregnation of the soil.

FIG. 1 shows the device section; in fig. 2 is a section A-A in FIG. I.

A device for the formation of wells in the ground includes a conical tip 1, at the top of which a pin hollow positive electrode 3 is mounted by means of a conical insulator 2. The positive pin electrode contains an internal storage capacitance 4, which is connected with the ground thickness by radial holes to the valves 5. through the hose 6 with the discharge mechanism (not shown). Insulating bushes are mounted in the body of the conical tip, inside of which are placed negative electrode rods 7 with seats 8. On the seats there is a closed current-carrying circuit 9. 30

The nature of the connection of the conductive loop of the circuit with the electrode rods allows the rods to rotate around its axis, and the mating rods with insulating bushings - 35 axial movement of the rods. One of the electrode rods (for example, the upper one) is coupled to the insulating sleeve by means of a threaded connection 10. Electrical wires 11 connected to the corresponding terminals of the current source (not shown) are connected to the electrode rods. The device is connected to the laid pipeline by means of 45 shank 12.

The device for the formation of wells in the soil works as follows.

Before starting the process of borehole formation, a polar-50 pin positive electrode 3 and a system of negative electrode rods 7 with a closed current-carrying circuit 9 are installed.

put well. A system of electrode rods 7 is effected by turning the upper electrode in an insulating sleeve. The devices are then mounted on the pipe pipe to be stretched by means of the shank 12 to process the well formation process. At the same time, a negative voltage is supplied to the electrode rods and a closed current-carrying circuit. A positive voltage is applied to the pin electrode 3, and a hydrophobic liquid, such as liquid glass, is supplied to the inner capacitance 4.

In this case, the hydrophobic liquid from the internal accumulative bone 4 of the pin electrode 3 through the openings with valves 5 enters the soil stratum. Under the action of an electric field created between a closed conductive loop and a pin electrode 3, the water in the ground medium moves to the negative electrode, and the released pores are filled with a hydrophobic liquid due to the pitch in the voids.

When the device is moving, the saturated soil is subsequently compacted with the lateral surface of the cone of the nechnik 1, forming an insulating layer of the earth's well.

The proposed design of the device has significant advantages over limestone.

The presence of a closed current-carrying circuit, together with negative electrode rods, allows us to carry out the process of assessing the group with a hydrophobic liquid in the smallest seals, i.e. the zones of origin are from the area of the well formation. In addition, a closed conductive loop allows a uniform closed electric field to be produced in the entire volume of the impregnated soil.
