PILE SUPPORT FOR STRUCTURES ERECTED ON PERMANENTLY FROZEN SOIL Russian patent published in 2010 - IPC E02D3/115 

FIELD: construction.

SUBSTANCE: pile support intended for use in erection of structures erected in regions with permanently frozen soil comprises metal or reinforced concrete tubular shaft 1 with closed ends, which is partially deepened into soil 2. Upper end 3 is a supporting platform. Support also comprises cooling device of seasonal effect. In deepened part of shaft 1 there is a reservoir 5 arranged with substance 7 that accumulates cold. Support feature is in making reservoir 5 from elastic material and its placement with adjacency to internal surface of shaft 1 wall, and also use of water as substance that accumulates cold. Cooling device is arranged in the form of one or several vertically oriented gravitational heat pipes 4 arranged outside tubular shaft 1 with zones of evaporation 11 and condensation 9, and transport zone 10 arranged in between. Besides evaporation zone 11 in each thermal pipe is located below, and zone of condensation is arranged higher than soil surface.

EFFECT: invention provides for improved reliability of structures, using cooled pile supports, in combination with improved efficiency of cooling and freezing.
