Recesses roads on permafrost

摘要

The invention relates to the field of construction, namely the construction of buildings in areas where permafrost vysokoldistyh ground or foundation soils with the presence of the buried ice. The recess road on permafrost soil layer comprises replacing the natural, and disposed on this layer structure carriageway for road or rail travel. The novelty of the proposed excavation is that it comprises a cooling side arrays, closely adjacent to the recess subject to the existing structures approximation dimensions. Side cooling array is an array of the replaced natural vysokoldistogo malovlazhnogo ground soil, the width of which is assigned at least to the depth of seasonal thawing malovlazhnyh replaced soils. On the sides of the array contains one or more cooling sections with steep slopes «i», allowing to drastically reduce the deposition of snow in these areas. Sloping «i» cooling portions is set to (1: 0) i (1: 0.75). Under construction roadway can be laid on the insulation layer width equal to the distance between the opposite lateral cooling arrays plus half the lateral width of the array of cooling in each direction. On the outer side of the cooling side of the array may be disposed insulation layer in width equal to at least two depths; seasonal thawing of soil in natural conditions on the territory adjacent to the recess. 1 bp f ly-1-yl.
