FIELD: construction.
SUBSTANCE: method of structure of slab foundation in soft permanently frozen soil with the additional change of temperature of permanently frozen solid mass, carried out by the method of forced controlled supply of thermal agent from external sources along the looped distribution mayor pipelines with the formation of ground slab, exceeding the sizes of the main slab foundation in plan, in this case the supply is carried out by vertical thermal elements equal to the projected thickness of the ground slab and manufactured in the form of loops, installed in the previously drilled wells connected to the loopback major pipelines, in this case the wells and trenches, after installation of vertical thermal elements and major pipelines into the soil, fall asleep.
EFFECT: reduction of labour intensity by the construction of foundations.
