FIELD: construction, pipeline.
SUBSTANCE: invention is related to construction of pipeline transport and is used for installation of pipeline that transports product with negative or time-variant temperature under conditions of watered tundra and swamps of the North. Set comprises erosion-preventive, heat-shielding and protective screens. Heat-shielding screen is arranged in the form of rolled flexible cloth from heat insulation material. Length of heat shielding screen makes at least sum of the following dimensions - size of soil disturbed in process of pipeline installation and doubled depth of seasonal melted layer. Erosion-preventive screen is arranged in the form of rolled flexible cloth from geotextile material capable of surface water filtration. Erosion-preventive screen dimensions are not less than corresponding dimensions of heat-shielding screen. Protective screen is arranged in the form of low-sized geomodule set, cellular structure of which is filled by loose material, for instance, soil. Protective screen dimensions are not less than corresponding dimensions of heat-shielding screen.
EFFECT: provision of pipeline quality and reliability, prevention of environment ecology parameters disturbance in process of construction.
