STRUCTURE FOR PROTECTION AGAINST LANDSLIP Russian patent published in 2004 - IPC

FIELD: building, particularly securing of sliding slopes, for development of built-up areas with unsteady soil consisting of crushed stone and clay. SUBSTANCE: structure includes drilled-and-filled piles arranged in rows and joined by grating, drainage system of porous concrete and discharge channel. Drilled-and-filled piles are arranged transversely to sliding slope. Alternate piles in row are formed as combined piles, which have lower part of heavy concrete, upper part of porous concrete and frame of non-corrosive reinforcement. Outermost and intermediate piles are completely made of heavy concrete. Structure has additional discharge channel formed as inclined drains into drilled wells starting in upper part end of combined pile. EFFECT: increased structure efficiency due to interception of underground water jets and decreased work content. 1 dwg
