Description

The invention relates to construction equipment and can be used for trenchless laying of underground utilities.

The purpose of the invention is to increase work efficiency by increasing the filtration rate of groundwater.

The drawing shows the device, a general view.

A device for driving bent holes in the ground includes a cone-shaped body 1, on the outer surface of which there are negative plates-electrodes 2 with through holes 3 and with insulator elements 4.

In the top of the cone-shaped case 1 an insulator 5 is mounted in the form of a conical sleeve, in the axial hole of which a positive pin electrode 6 is located, the part of the outer surface of which has a threaded surface 7. The latter enters the interface with the insulator disk 8.

In the internal cavity of the device, in the area of the negative plate electrodes 2, chambers 9 are provided, which communicate with hoses 10 with a vacuum pump (not shown).

Electrical plates 11 connected to the corresponding terminals of the current source (not shown) are connected to the electrode plates 2 and the pin electrode b. The device is connected to the piping through a cylindrical shank 12.

The device works as follows.

Before starting the process of boreholeing, the outreach of the pin electrode b is set by means of vrash, around its own axis. Protrusion of the pin electrode 6 affects the electrostatic field strength between the positively charged pin electrode 6 and the negatively charged plate electrodes 2 and depends on the physical and mechanical properties of the soil. After that, the device is mounted on the laid pipeline

by means of cylindrical shank 12, and the process of well formation begins.

If it is necessary to change the direction of the well being laid, for example upwards, a negative voltage from the power source is applied to the top plate-electrode 2, and a positive voltage is applied to the pin electrode. At the same time, in the chamber 9 of the upper plate-e; 1, electrode 2, the vacuum pump creates vacuum discharge. The holes 3 of this plate communicate the chamber 9 with the bottom surface.

Under the action of an electrical voltage and discharge created in chamber 9, the water enclosed in the holes of the soil moves from the positive to the negative pole. As a result, the surface of the plate-electrode 2 is wetted and the physico-mechanical characteristic of the surrounding soil C; IOH is changed to be more saturated with water.

When extending the device

Forward and the coeffer-wetted zone, the soil rubbing force on the device is easier to compact in the area of the connected negative plate-electrode than in the rest of the interface between the soil and the body. The result of this is a change in scarring of the axis of the well 1X.

A device for drilling distorted wells, including a cone-shaped body with lamellar negative electrodes and a five-point positive electrode at the top of the cone-shaped body, which in order to increase the efficiency of operation by increasing the filtration rate of groundwater, it has chambers made in the body of the body and pa: niemeHtn: .ie under the plate negative electrodes, and pipes for connection to a vacuum pump, in this case; communication with the atmosphere.
