EARTHWORKS STRENGTHENING METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC E02D17/20 

FIELD: construction.

SUBSTANCE: invention relates to construction, including transport, road and hydraulic engineering, and can be used for strengthening earthworks for various purposes, including roadbed embankments, dams, earthworks slopes for construction on them of various facilities, etc. constructed on weak, including swampy soils. The method of earthworks strengthening involves drilling along the earthworks of wells, filling of wells with hardening material and formation of pile trunks, while strengthening earthworks built or being built on weak or frozen grounds where wells are drilled from a mobile platform, supporting pipes are used, which are mounted in rows from the outer sides of paths from upper surface of the earthworks with cutting through the earthworks structure, its underlying layer of weak or mobile soil and penetration into underlying durable ground layer. The wells are filled with a hardening conductive material, the working electrode is lowered, which is connected to the electric impulse unit, the specified number of electrical discharges is performed. In each of supporting pipes, which support the movable platform with installed equipment, at least one holding and at least one drain hole are made. The holding hole is hooked with the rig winch hook and is used for retrieval and immersion of pipes from wells or into them, respectively. First, each of the wells is filled with hardening conductive material, and then the working electrode is lowered into the borehole and a predetermined number of electric discharges is performed.

EFFECT: accelerating the production process, increasing the reliability of strengthening and providing the use in conditions of any weak and moving soils.
