HEAT INSULATING LAYER OF BUILDING STRUCTURE Russian patent published in 2008 - IPC E02D17/20 

FIELD: construction.

SUBSTANCE: invention may be used for reinforcement of slopes in embankments of motor and rail roads, arrangement of pipelines banking, reinforcement of ditches and other minor drains, and also in construction of other structures in the zone of permanently frozen soils and neighbouring territories, and also in building of temporary roads under complicated conditions (blown sands, watered grounds built with clay or organogenic soils, etc.). Heat insulating layer of building structure that is mainly used in zone of permanently frozen soil contains geotechnical volume grating, in cells of which hydrophilic fibre material is installed. Fibre material in cells is in feebly compacted state with compaction coefficient of 0.7-0.8, and cells of geotechnical volume grating are closed with geotextile fixed with brackets in walls of cells. As fibre material natural material is used, such as peat, or man-made material on the basis of fibre polyethylene such as padding polyester.

EFFECT: provision of building structure functioning in wide range of temperatures changes both in minus and plus intervals, increase of operation life duration.
