FOUNDATION OF RESERVOIR WITH IMPROVED HEAT INSULATION PROPERTIES Russian patent published in 2019 - IPC E02D27/35 

FIELD: construction.

SUBSTANCE: invention relates to construction and can be applied to foundations of tanks for storage of oil and its processing products under conditions of seasonal frosts and permanently frozen soils in the Far North. Foundation of reservoir represents prepared soil in form of pad made of medium-grained sand and artificial additive. Artificial additive represents disperse heat-insulating material in form of granulated foamed polystyrene, maximum volume V_GSM which in total volume V_F foundation pad is determined by the formula V_GSM=V_F⋅n, where V_F – the total volume of the foundation pad, cub. m; n is the maximum volume fraction of the artificial additive in the form of dispersed heat-insulating material in total volume V_F of foundation pad.

EFFECT: technical result is to reduce the heat exchange directly between the bottom of the tank and the seasonal frozen and permanently frozen soils in the Far North, to prevent or reduce the thawing of the soil bases and, as a result, to prevent their loss of stability while ensuring the permissible value of relative vertical deformation of foundation reservoir.
