METHOD FOR INSTALLATION OF LIGHT COOLING DEVICES FOR TEMPERATURE STABILIZATION OF PERMANENTLY FROZEN GROUNDS Russian patent published in 2016 - IPC E02D3/115 

FIELD: construction.

SUBSTANCE: invention relates to construction in regions with complex engineering and geocryological conditions and can be used for stabilization of permanently frozen and freezing of weak plastic frozen soil. Installation method of light cooling devices for temperature stabilization of permanently frozen grounds includes drilling through flat-dipping well drawing cooling device equipped with pipes of evaporator and condenser connected bellows sleeves, protected bands, to the well to design position, installation of cooling elements on the condenser pipe cooling device. Cooling device previously laid in protective holder consisting of casing pipes of coupling connection, both end faces of which are equipped with damping gaskets and screwed covers, drawn to the well to the design mark with simultaneous expansion of the well. Protective shell is removed from condensing sections of pipes of the cooling device, and the pipes are attached with anchors. In the gap between the protective case and well walls installed cementing pipe and the drilling machine protective holder with simultaneous supply of cement mortar with water/cement ratio W:C=0.5 in clearance between the cooling device and the walls of the well.

EFFECT: increasing carrying capacity of soil bases, reduced load of structures on light-weight design of heat stabilizers, low material consumption for construction and erection works.
