Abstract

The invention relates to the technical field of pipelines, in particular to a large-diameter long-distance heat preservation combined pipeline structure and a construction method thereof. The structure comprises pipeline monomers and an integral node; each pipeline monomer comprises an outer-layer GFRP circular pipe, an inner-layer GFRP circular pipe, a self-compaction fine aggregate concrete layer and a heat preservation plate, wherein the two end parts of the pipeline monomer are provided with bolt holes correspondingly, and the outer wall of the outer-layer GFRP circular pipe is provided with an outer-layer GFRP circular pipe reserved bolt hole; and the two pipeline monomers are connected through the integral node, the integral node is connected with the bolt holes in the end parts of the two pipeline monomers through a high-strength bolt, a concrete pouring hole and an exhaust hole are formed in the outer wall of the integral node, and the concrete pouring hole and the exhaust holeare distributed at an interval. The large-diameter long-distance heat preservation combined pipeline structure and the construction method thereof solve the problems of small diameter, poor stability, poor permeability resistance and poor heat preservation performance generated when a medium is conveyed in a high-severe cold area of a traditional pipeline.

Description

Technical field: [0001] The invention relates to the technical field of pipelines, in particular to a large-diameter long-distance thermal insulation composite pipeline structure and a construction method thereof. Background technique: [0002] Conventional long-distance pipelines are mostly round steel pipes and reinforced concrete round pipes, with diameters ranging from 0.5 meters to 1.5 meters. One end adopts the form of an enlarged head, and the connection between the pipes is realized through the head. The liquid is transported in the steel pipe all the year round, and it is easy to rust. Long-term erosion will reduce the effective thickness of the pipe wall, reduce the rigidity of the pipe wall, and local buckling will easily occur under the pressure of the soil and the outside world. At the same time, due to the erosion of the inner wall by the liquid in the pipeline, there are more and more impurities. It is difficult to meet the quality inspection standards, and th...
