Abstract

The invention relates to an oil gas multiphase conveying integration multicavity pipeline structure system and a construction method thereof, and relates to the pipeline technology field. The oil gasmultiphase conveying integration multicavity pipeline structure system is formed by sequentially connecting three pipelines through GFRP (glass fiber reinforced polymer) buckling energy dissipation dampers, wherein axes of the three pipelines are sequentially connected to form an equilateral triangle, each pipeline comprises a pipeline monomer and an integrated node, each pipeline monomer comprises an outer layer GFRP round pipe, an inner layer GFRP round pipe and a self-compaction fine aggregate concrete layer, bolt holes are formed in two end parts of each pipeline monomer, an outer layer GFRP round pipe reserved bolt hole is formed in the outer wall of each outer layer GFRP round pipe, each two pipeline monomers are connected through an integral type node, each integral type node is connected with the bolt holes in the end parts of each two pipeline monomers through high strength bolts, concrete pouring holes and vent holes are formed in the outer wall of each integral type node, and the concrete pouring holes and the vent holes are distributed at intervals in each integral type node. The oil gas multiphase conveying integration multicavity pipeline structure system and the construction method thereof solve the problems that a traditional pipeline is small in diameter, and poor in stability and permeability resistance.

Description

Technical field: [0001] The invention relates to the technical field of pipelines, in particular to an integrated multi-cavity pipeline structure system and construction method for oil and gas multiphase transportation. 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, ...
