The disadvantage of this method is the prohibition of its use in the conditions of reconstruction, within existing facilities because of the danger of uncontrolled explosion from detonation and others closest to the invention in its essence and the achieved technical result is the method of construction of printed structures in the soil, including the formation of the well, the flow in the well-hardening material, install it with electrogarden high-voltage electrical discharges through the emitter retrieve it from the well [2].

The disadvantage of this method is low efficiency in most soil conditions due to the inevitable loss of energy in the electro and the impossibility of increasing the capacity of the process equipment in the building conditions in the necessary conditions. Known submersible borehole bit station [3] for a treatment of the walls of oil wells, the disadvantages of which is the low energy consumption, which does not allow to dramatically influence the properties surrounding the borehole soils when used in construction purposes and which does not allow increasing the carrying capacity of the system "soil - printed design in the ground".

The present invention is to increase the efficiency of the seal surrounding the printed design of the ground and the material of the structure to ensure the consistency of their work, while ensuring the possibility of the construction of the ground printed designs such as the construction of new buildings and renovation of existing facilities or strengthened, including in the conditions of dense construction and expansion thereby the area of use.

The problem is solved due to the fact that the method of construction printed design is within the electrodes inventory electric radiator, connected to a source of pulsed electrical discharge excitation high-voltage electrical discharges through the emitter retrieve it from the well, according to the invention, at least one high-voltage discharge is produced simultaneously with bringing in the interelectrode space of the emitter adetomyrma water-filled exothermic mixture and its combustion at the high-voltage electrochemical explosion with the release of gases, vapor and plasma and creating a shock wave and pressure up to 100 MPa, further widening the hole with soil compaction her walls and filling the hole hardening material. At the same time as adetomyrma water-filled exothermic mixture can use a paste containing aluminum powder, nitrate and water. As the hardening material can be used, for example, the concrete mix. Can produce bezrobocie electrical discharges. High-voltage discharges can produce, at least at the location of the radiator on the bottom of a well.

The emitter can equip partitioned cartridge for storage and batch submission adetomyrma water-filled exothermic mixture in the production of ocher is, odorou supply partitioned cartridge for storage and batch submission adetomyrma water-filled exothermic mixture, and the station is dipped into the well together with the emitter. After removing the radiator from a well in the hardening material can immerse reinforcement cage.

Prior to immersion of the emitter into the hole to him able to attach the detachable connection of the reinforcing frame, and before removing the radiator produce disconnecting it from the reinforcing frame, which is left in the well.

During the construction of printed support structure in soils with inclusions of rock electrical discharge with electrochemical explosion can produce with the simultaneous destruction of rocks and education in the destroyed area fortified hardening material of the array.

The emitter can be mounted on a hollow rod, and the flow in the interelectrode space portion adetomyrma water-filled exothermic mixture is performed through the cavity of the rod. The hole in the ground may be formed by drilling or using the inventory casing, removing them produces cyclical implementation of each cycle before the next stand is a W inventory casing with a lost tip, after disconnection, which make removing the casing pipe.

In the soil can build a pile or anchor cylindrical or in the form of a truncated cone, facing a large base up or down, or pile or anchor with at least one extended area, height, or wall or walling adjacent to each other piles or piles with Bay adjacent to each other, or reinforcing the soil structure in the form of piles or anchor with at least one extended area. Thus reinforcing the soil structure may build up in the body of the mound with the location of the piles and/or anchors rows and/or tiers, respectively, the width and height of the embankment, or reinforcing the soil structure can be build in bulk soil or ground natural addition, located at newly constructed or reinforced retaining wall, or the wall of the embankment or abutment of the bridge, or viaduct or trestle.

The technical result provided by the present set of features is to improve the effectiveness of the seal surrounding the printed design of the ground and the material of the structure to provide a joint of their work and increase the carrying capacity of the system "Okruashvili new structures, and renovation of existing or strengthened, including in the conditions of dense construction and expansion thereby the area of use.
