METHOD OF ARRANGEMENT OF FOUNDATION SLAB ON PILES FOR LOW-TEMPERATURE PRODUCT TANK Russian patent published in 2015 - IPC E02D27/38 

FIELD: construction.

SUBSTANCE: method of arrangement of the low-temperature product tank foundation in weak permafrost soil supported by the pile field cooled by additional freezing of the permafrost soil massif differs in that an additional freezing of the permafrost soil massif with piles is performed by depth thermoelements using the method of forced adjustable supply of coolant with pre-set temperature into them from the external source of its cooling through girdled distributive lines, and for freezing of the soil base under the slab during storage of the product its own negative temperature is used. After certain time interval when the range of frost penetration in the soil base from the low-temperature product in the tank achieves the design temperatures, the additional forced freezing by the deep thermoelements is stopped partially or completely.

EFFECT: improvement of reliability of the foundation slab, increase of profitability of works at operation of foundation slabs in ductile and frozen and salted permafrost soil.
