SYSTEM FOR TEMPERATURE STABILISATION OF STRUCTURES FOUNDATION ON PERMAFROST SOILS Russian patent published in 2011 - IPC E02D3/115 

FIELD: construction.

SUBSTANCE: system for temperature stabilisation of structures foundation on permafrost soils equipped with hydraulic lock, levelling vessel, serially connected to condenser and evaporator arranged in foundation soil fill, joined to pipelines that supply and drain heat medium. It additionally comprises vertical heat-exchangers-evaporators arranged along depth of foundation soil fill, which are made as tube in tube, and their lower ends are plugged, and upper ends are connected directly to evaporator, which is arranged in the form of system of pipes laid in horizontal plane evenly along whole area of foundation soil fill, equipped with a layer of heat insulation joined by means of pipelines by its supply end to condenser and by its drain end - by means of pipelines with a levelling vessel. Height of above mentioned vertical heat-exchangers-evaporators is equal to at least distance "b" between border of depth of "X-X" evaporator arranged in the form of piping system laid in horizontal plane evenly along whole area of foundation soil fill, and upper border of "Z-Z" permafrost soils depth. Lower part of inner pipes of specified heat-exchangers-evaporators arranged concentrically to outer pipes is arranged with perforation, and upper part is arranged as funnel-shaped.

EFFECT: improved reliability, efficiency, operational and technical properties of systems for temperature stabilisation, reduced material intensity.
