Abstract

The invention relates to a heat-insulation pipe fixing pier and a mounting construction method thereof, and belongs to the technical field of pipe engineering. A heat-insulation layer is arranged on the outer surface of the heat-insulation pipe fixing pier, and rendering coat mortar is arranged on the outer surface of the heat-insulation layer; and the heat-insulation layer is fixed on the outer surface of the fixing pier through an adhesive or expansion screws, and is made of rigid polyurethane foam or rigid extruded polystyrene foam boards. The invention further relates to a mounting construction method of the heat-insulation pipe fixing pier. The heat-insulation layer is arranged on the outer surface of the heat-insulation pipe fixing pier, loss of heat of a pipe system into a frozen earth stratum is stopped, so that energy consumption of the pipe system is reduced, and heat balance of the frozen earth stratum is protected.

Description

technical field [0001] The invention relates to a heat-insulating pipeline fixing pier and an installation and construction method thereof, belonging to the technical field of pipeline engineering. Background technique [0002] The buried heating transmission pipeline passes through the permafrost area, and an insulation layer is generally provided on the outer surface of the pipeline to prevent the heat loss of the pipeline and destroy the heat balance of the surrounding permafrost layer. In order to constrain the displacement of the pipe due to thermal expansion and contraction at the part of the hot-simmering bend, a fixed pier (also called an anchor pier) needs to be set. The pipes and anchor flanges in the fixed pier have no insulation layer and are in direct contact with the concrete, and the surface of the fixed pier is not provided with an insulation layer, resulting in a large amount of heat loss in the piping system at the fixed pier. Permafrost is extremely sensi...
