FIELD: construction.
SUBSTANCE: method includes driving of a casing pipe for depth of not less than the depth of seasonal freezing-thawing of soil. Drilling of the pilot hole for depth of at least the normative value of soil freezing. Drilling of soil from the casing pipe cavity. Pouring of the hardening material in the volume necessary for filling of cavities between the pilot hole and the pile from the bottom of the pilot hole to the bottom of the level of the layer of seasonal freezing - thawing of soil. Submersion of a tubular pile into the pilot hole with a mortar. Filling of the cavity between the pile and casing pipe with non-swelling loose inert material.
EFFECT: increased bearing capacity of driven cast-in-situ piles.
