FIELD: construction.
SUBSTANCE: method to arrange pile foundations preferably for low-rise houses, masts, and advertisement boards in freezing heaving soils includes submersion of short steel piles into soil by means of their screwing down to the rated depth, arrangement of banding beams-caps, installation of a heat insulation material layer above the piles and under the beams-caps. Piles are submersed in winter period, after partial or full freezing of soil. Length of piles is accepted as not less than the rated depth of soil freezing. Then beams-caps are mounted. The arrangement of the heat insulation material layer is started after soils thaw down to safe depth determined by piles calculation for resistance to frost heaving forces action. Surface structures (houses, masts, advertisement boards) are erected both before and after full thawing of soils down to safe depth.
EFFECT: higher bearing capacity, simplified works of foundations arrangement in winter period, in case there are heaving soils present in the base.
