METHOD FOR HEAT STABILIZATION OF PERMAFROST SOILS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC E02D3/115 

FIELD: construction.

SUBSTANCE: device for heat stabilization of permafrost soils contains at least two soil heat stabilizers, based on biphase thermosyphones, comprising the aboveground condenser part and the underground transport and evaporation parts, and at least one heat-conducting element made in the form of a plate of heat-dissipative material with the thermal conductivity of at least 5 W/m⋅K. At least two soil heat stabilizers are installed on both sides of the underground-laid pipeline and at least one heat conductive element is installed under the heat insulation material separating the underground-laid pipe from the roof of permafrost soils and has openings for connecting to the evaporating parts of at least two soil heat stabilizers.

EFFECT: increasing the efficiency of preserving permafrost soils or freezing weak soils of the bases of pipeline system objects to ensure the safety during the designated service life at design modes.
