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 foundations on permafrost soils comprising a hydraulic lock, a levelling vessel, connected to a condenser and joined with them by means of pipelines that feed and drain a coolant, an evaporator arranged in the foundation soil fill. It comprises an additional evaporator with a system of pipelines and a hydraulic lock, besides, both evaporators are arranged evenly along the whole area of the foundation soil fill, equipped with a layer of heat insulation, and are joined by means of pipelines by means of their draining ends - to upper points of the levelling vessel, and with feed ends the main and additional evaporators are connected in the lower point of the condenser and the lower point of the levelling vessel, accordingly, via the appropriate hydraulic locks.

EFFECT: increased efficiency and speed of freezing at the initial stage of the system start-up, reduced material intensity.
