METHOD OF THERMAL STABILIZATION OF SOIL BASE OF PILE FOUNDATION OF PIPE SUPPORTS

摘要

FIELD: building.;SUBSTANCE: invention relates to heat engineering in the field of construction, namely, the thermal stabilization of soil basements of pipe pile foundation poles and piping of underground installation located on permafrost soils. The process of thermal stabilization for soil base pile foundation supports of the pipeline and the pipeline of underground installation is that they produce the recess of icy soils in the foundations of pile foundations supports of the pipeline and the pipeline of underground installation and packing into the recess the composite material, the installation of, at least, two heat stabilizers of the soil at the edges of the recess, wherein the composite material has the composition according to the ratio of its components in wt %: Gravelly sandy soil - 60-70, foamed modified polymer - 20-25, the heat transfer fluid - 5-20 or a large sandy soil - 70-80, 10-15 foamed modified polymer - 10-15, the heat transfer fluid - 5-20. For impregnation of the polymer the heat transfer fluid is chosen, which is characterized by high heat capacity and low freezing point up to -25°C.;EFFECT: invention improves the reliability of the structure in the construction of pile foundation supports of the pipeline and the pipeline of underground installation located on permafrost soils, ensures the safe operation of main oil pipelines in the design conditions for a specified period on the territory of permafrost.;6 cl, 1 dwg, 1 tbl
