METHOD FOR STABILIZATION OF EARTH STRUCTURE Russian patent published in 1998 - IPC

FIELD: construction engineering. SUBSTANCE: method is intended for stabilization of earth structures which are being built or been built already on loose base such as on swampy base. According to method, drilled along earth structure are bore-holes with utilizing of casing pipes. Drilled for each route are at least three rows of bore-holes. Drilling is performed from upper surface of earth structure with driving through its body, layer of peat with embedding into mineral bottom which is underlying beneath layer of peat. Penetration into mineral bottom is by 1.0-1.5 m. Then, successively lowered into bore-holes is working electrode which is connected to electric-pulsing unit. Thereafter bore-holes are filled with hardening electric-conducting material, and determined number of electric discharges are made at level of bore-hole lower part. Casing pipe is lifted together with electrode to upper part of bore-hole, and without removing electrode, hardening electric-conducting material is added by pouring-in. Then, electric charges are performed for second time at level of bore-hole upper part. In result of aforesaid procedure, pileworks are created which combine piles of each row. Layer of underlying material is then placed above them. Application of aforesaid method ensures reduction of labour and material expenses, improves quality of stabilization, reduces values of elastic vibrations of earth structure at any steepness of slopes, prolongs service life of stabilized earth structure. EFFECT: higher efficiency. 2 dwg
