METHOD FOR ASSEMBLING COOLING DEVICES FOR TEMPERATURE STABILIZATION OF PERMAFROST SOILS UNSTABLE IN WELL WALLS Russian patent published in 2017 - IPC E02D3/115 

FIELD: construction.

SUBSTANCE: invention relates to construction in areas with complex engineering and geocryological conditions, where thermostabilization of permafrost and plastic-frozen soils is applied, and can be used to maintain their frozen state or freezing, as well as in the wells which are unstable in walls and prone to landsliding and caving formation. The method includes drilling a vertical well with a hollow auger column (AC) to a design mark, followed by removal of a removable central chisel, installing a cementing head with a hose from the cement pump on the upper part of the AC, extracting the AC with simultaneous feeding of the cement slurry through the AC until filling the well, and installing a cooling device with a heat-insulating casing on the condenser (at sub-zero air temperatures), which is dismantled after the cement slurry hardening.

EFFECT: allows to provide processability of cooling devices assembly, efficiency of soil cooling process and durability of cooling structures buried in a soil mass.
