LANDSLIDE PROTECTION WORKS Russian patent published in 2010 - IPC E02D27/02 

FIELD: construction industry.

SUBSTANCE: landslide works include rows of support bored piles, combined with foundation frame, arranged across landslide slope and drain system. In order to protect against surface landslides and mud flows, piles are cut, every two of which have, next but one, length which is less than height of landslide part of slope soil and connected above moving soil by means of foundation frames to piles reinforced with frameworks and embedded in non-shifting soils; at that, drain facilities made by means of trenchless method are connected to non-reinforced piles.

EFFECT: reducing labour input, terms of well construction and increasing slope stability factor.
