METHOD TO PREVENT DEFORMATIONS OF LINEAR STRUCTURES ERECTED ON LANDSLIDE SLOPES OR MANMADE SLOPES ON MELTING PERMAFROST SOILS Russian patent published in 2015 - IPC E02D17/20 

FIELD: construction.

SUBSTANCE: method to prevent deformations of linear structures, erected on landslide slopes or manmade slopes on melting permafrost soils, includes erection of a working site, installation of piles into slope soil, combination of piles into a single grill. After submersion of piles into soil at the free end of each pile they install a reinforced concrete head, and combination of piles into a single grill is carried out by installation of a vertical geogrid, stiffly connected to heads of piles and layers of horizontal geogrids arranged above heads of piles. The working site from the bottom of the pile heads to the first layer of the horizontal geogrid and also gaps between layers of geogrids are filled with crushed stone and compacted. Horizontal geogrids are installed with the condition of their partial arrangement in a non-moving massif of the slope soil or natural slope.

EFFECT: prevention of deformations of motor and rail roads on slopes under conditions of melting permafrost soils in process of operation of structures, reduced material intensity, realisation of anti-landslide actions.
