DEVICE TO HOLD LANDSLIPS IN SEISMIC ZONES Russian patent published in 2011 - IPC E02D29/02 

FIELD: construction.

SUBSTANCE: device to hold landslips in seismic zones includes piles deepened into a non-displacing soil with staggered arrangement in plan. Flexible piles that consist of three reinforcement rods with triangular arrangement in plan, onto which solid or hollow concrete elements are put, being separated with a soft pad and tightened at both ends of the flexible pipe with bolts, are inserted into previously drilled deep holes with deepening into the non-displacing soil below the sliding surface, across the slope or the potential direction of the landslip. A net apron is attached to the upper part of the flexible pile, having a triangular shape in plan.

EFFECT: improved efficiency and reliability of slope protection against slip in seismic zones, reduced material intensity.
