STRUCTURE TO PREVENT FROST HEAVING OF SOIL Russian patent published in 2014 - IPC E02D27/35 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction and operation of buildings and structures, specifically to protection against frost heaving of shallow foundations, road surfaces and building structures, in particular, ramps and pavements that surround buildings. A structure for prevention of frost heaving of soil includes a system of wells, including damping wells, which are drilled near or as inclined under the foundation in the underlying soil layer for depth of its freezing and filled with a working medium. Each damping well comprises a garland from interconnected reservoirs, besides, in the lower part of the well there are preferably perforated reservoirs arranged, filled with a dry mix of salt and sand at the ratio of 1:2, and in the upper part of the well there is one or several reservoirs filled with a salt solution of at least 0.5 kg of salt per 10 l of water, at the same time reservoirs are equipped with diametrically arranged protrusions that communicated with the inner space of wells closed with detachable heads.

EFFECT: higher reliability, durability and efficiency of damping piles.
