ANTI-LANDSLIDE STRUCTURE Russian patent published in 2005 - IPC

FIELD: building, particularly for slope consolidation and for stabilizing deep front landslide areas.

SUBSTANCE: structure includes foundation mat and piles formed in wells grouped in rows. Upper pile parts are embedded in foundation mat, lower one is restrained by not-sliding ground layers. Piles are composite along their lengths. Central pile parts are not filled with concrete. Heights of upper and lower pile parts decrease towards landslide head. Structure to prevent deep front land-slides comprises separate local pile groups connected by foundation mats and located within landslide body boundaries. Each foundation mat has tension bars anchored in stable slope layers and arranged under and above foundation mat along slope to retain thereof against displacement and rotation.

EFFECT: improved slope stability, increased operational reliability of structure built on wide landslides, reduced building time and material consumption.
