METHOD FOR PREVENTION OF LANDSLIP FORMATION Russian patent published in 2012 - IPC E02B11/00 E02B3/04 

FIELD: construction.

SUBSTANCE: method consists in capture of underground waters with the help of a full catch drain mine perpendicular to a direction of a flow of water flowing out from water-bearing horizons and connected with vertical wells drilled from day surface. Vertical wells are through filters crossing water-bearing horizons, and water-reducing wells, which on crossing with water-bearing horizons are equipped with filtering elements. Additionally from the day surface along the line of through filters, water monitoring wells are laid for water level monitoring in water-bearing horizons. At the same time at first from the day surface of a landslip-to-landslip collar under water-bearing horizons and landslip massifs with an inclination to the line of location of a shaft water-discharge collector for water self-flow, the well is tunnelled by means of horizontal directed drilling perpendicularly to the direction of water flow leaking out from water-bearing horizons. Into this well a pipe of a water-discharge pipeline perforated on top to the middle of cross section is pulled with an inclination to the shaft water-discharge collector for self-flow of collected water. Afterwards on top or at the bottom of the landslip inclination a well is tunnelled with directed drilling, where a pipe of the shaft water-bearing collector is pulled into, stretching under sections of water flows in a water discharge pipeline, where an inspection shaft is arranged. In the shaft a water-discharge pipeline is connected with a shaft water-bearing collector with the help of a T-shaped nozzle. The connection branch of the nozzle towards the shaft water-bearing collector may be of different length. On top towards the performed water-bearing pipeline, there are vertical wells reaching, equipped with perforated drainage pipes filled with a replaceable filtering material. Between vertical wells aside from the water-bearing pipeline there are water monitoring wells arranged. All pipelines and vertical wells coming out to the surface and covered with protective caps.

EFFECT: higher safety of a device of a drainage transport hydraulic system for prevention of landslips formation, which provides for higher reliability of the proposed method.
