FIELD: construction.SUBSTANCE: cooling device for depth temperature stabilisation of soils of foundations of buildings and structures comprises a tight tubular body with zones of evaporation, condensation and a transport zone between them, made as capable of filling with coolant. At the same time the body comprises a heat exchanger, which includes a pipe of the condensation zone body, a receiver made of a pipe of larger diameter than the diameter of the body, having a plug on top and tightly installed at the end of the pipe of the condensation zone body. The device also includes at least two hollow drainage tubes, the diameter of which is less than the diameter of the body pipe, made with external ribbing, arranged vertically around the pipe of the condenser zone of the body and connected by upper nozzles with a receiver, and by lower nozzles - with a cavity of the gap formed by inner walls of the coupling connecting the lower part of the pipe of the condenser zone of the body with the external support bushing welded to the upper section of the transport zone pipe. The device additionally comprises a receiving bushing made in the form of a section of a pipe of smaller diameter than the diameter of the body connected via an adapter with the lower end of the pipe of the condenser zone and placed partially in the upper part of the pipe of the transport zone of the body with a gap relative to its internal side surface. And the pipe of the body in the evaporation zone is made with alternating cross section and has at least one transition to a pipe of smaller diameter.EFFECT: increased bearing capacity of soils, simplified installation and dismantling of a structure.8 cl, 2 dwg |
