COOLED 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 construction of structures erected in regions with permanently frozen soil comprises metal or reinforced concrete shaft 1 partially deepened into soil 2 and equipped with supporting platform 3 on the side of upper end. Support also comprises cooling device of seasonal action and reservoir 5 with substance 7 that accumulates cold. Support feature is in making reservoir from elastic material and placement of it outside shaft 1 in vertical well 13 closed with cover 14 with its adjacency to its walls, and also use of water as cold-accumulating substance. 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 supports of abovementioned design, in combination with improved efficiency of cooling and freezing, and also possibility to use supports with monolithic shaft.
