COOLING STRUCTURE FOR EARTH STRUCTURES ON PERMANENTLY FROZEN SOILS AND ERECTION METHOD THEREOF Russian patent published in 2016 - IPC E01C3/06 

FIELD: construction.

SUBSTANCE: invention relates to construction and can be used in construction and reconstruction of earth structures erected on permanently frozen soils. Cooling structure for earth structures on permanently frozen soils is a coating of stone casting, laid on slope across longitudinal axis of earth structure, at least in two layers. Each layer of rock outline is made of artificial stone in form of a rectangular parallelepiped, in which is embedded geosynthetic mesh intended to hold artificial stone in design position. Artificial stone in steps is placed in longitudinal and transverse directions. Geosynthetic mesh in each artificial stone bottom layer is embedded in a plane parallel to its base, and geosynthetic mesh in each artificial stone of upper layer - in its diagonal plane. Each artificial stone of upper layer is arranged between adjacent artificial stones of bottom layer. Geosynthetic mesh in rocks of lower and upper layers is located parallel to lower edge of each of artificial stone of top layer of contact in lengthwise direction to upper ribs of two adjacent artificial stones and in transverse direction, at least, with upper ribs four adjacent artificial stones of lower rock outline.

EFFECT: technical result is to increase degree of cooling of base and near-bottom area of earth structures at closed surface structure of cooling in winter, maintaining high stability of earth structures, increasing degree of adaptability in construction design.
