METHOD FOR THERMOSTABILIZATION OF SOIL AROUND PILES Russian patent published in 2022 - IPC E02D27/35 

FIELD: soil thermal stabilization.

SUBSTANCE: invention relates to the field of thermal stabilization of the soil around the piles by the method for forced controlled supply of a coolant of a given temperature to the thermoelements from a refrigeration machine. The method for thermal stabilization of the soil around the piles includes freezing the array of permafrost soil with piles, thermoelements by the method for forced controlled supply of a coolant of a given temperature to them from an external cooling source. The cooled coolant from the outlet of the refrigeration machine is fed through a tube to the inlet of the cooled coolant collector, where it is distributed along the mains, then it enters sequentially into the hose, transport sections, inlet pipe and thermoelement, which is installed inside the pile at a depth that depends on the zone of soil thawing, and The inner space of the pile is filled with a non-freezing liquid, which improves the heat exchange between the pile body and the thermoelement. Passing through the thermoelement, the coolant heats up, and the temperature of the pile body and the soil adjacent to the pile decreases, after which the heated coolant sequentially enters the transport sections with the heated coolant, the hose, the line and the collector, at the inlet of the refrigeration machine.

EFFECT: increasing the efficiency of the soil thermal stabilization process.
