BASIS STRUCTURE FOR BUILDING CULVERTS OF SITE-ACCESS MOTOR ROADS AND ROADS WITH LOW MOVEMENT INTENSITY, LAID IN MARSHLAND Russian patent published in 2017 - IPC E01C3/06 

FIELD: construction.

SUBSTANCE: base structure for building culverts includes a frozen peat slab, a heat-insulating layer, a culvert, subgrade soil, and a cooling system. The cooling system consists of heat-conducting pipes made of heat-dissipating plastic, and embedded in the frozen peat slab, connected to the outputs of cold conductors to the surface. A heat-insulating layer is laid between the culvert and the frozen peat slab.

EFFECT: possibility of renewing the base without the major overhaul.
