Scientific novelty

It is proposed to implement controlled cooling of the soil around piles using coils lowered inside the piles to various depths. The adjustable immersion depth of the coil allows for soil thermal stabilization that accounts for the specific placement of technological heat sources on the surface, terrain features, prevailing meteorological conditions, etc.

Advantages

Flexible control of the soil thermal stabilization process through adjustable lowering depth of coils inside piles without the need to prepare coolant of various temperatures

Commercial implementation

The invention can be applied during the construction and subsequent operation of pile foundations, including at oil and gas production, processing, and transportation facilities
