STRUCTURE FOR REINFORCEMENT OF SLOPES OF EARTH STRUCTURE IN WEATHERABLE ROCK SOILS Russian patent published in 2014 - IPC E02D17/18 

FIELD: construction.

SUBSTANCE: invention relates to construction and operation of earth structures under complicated natural and climatic and engineering and geological conditions and may be used in construction and reconstruction of linear structures in sections of weatherable rock soils, also permafrost ones (railway and motor roads, manifold pipelines, dams and weirs). The structure for reinforcement of slopes of earth structures in weatherable rock soils, comprises a upland ditch, made in the upper part of the slope of the groove of the railway track along the earth structure above the border of the active layer reinforced with coarse clastic soil. At the slope there are at least two alternating ledges and two rollers, at the same time the upper roller is made between the upland groove and the upper ledge, and each subsequent roller - between the adjacent ledges. Rollers are made of fine-dispersed soil coated with a gravel-crushed stone soil. The area of the cross section of ledges is comparable with the area of the cross section of rollers, the volume of finely-dispersed and crushed stone soils has the ratio of 1 to 4-6.

EFFECT: increased service life of an earth structure up to the normative life and more than that due to colmation of pores and cavities of soils in slopes of the base, lying below the depth of a layer of seasonal freezing, formation of a permanent live section of soil flow in profile and considerable reduction of water migration from soils below depth of seasonal freezing into soils of an active layer.
