Abstract

The invention relates to a complex-shaped anti-corrosion pipeline for a special tunnel structure and a forming method of the complex-shaped anti-corrosion pipeline, and belongs to the technical field of formation of anti-corrosion structures of metal pipelines. The complex-shaped anti-corrosion pipeline sequentially comprises a pipeline main body, an anti-corrosion layer, an isolation layer and an outer protection layer from inside to outside, wherein the pipeline main body is a metal pipe; the anti-corrosion layer is a fluoride film; the isolation layer comprises a sponge layer and a water absorption film layer; and the outer protection layer is a soft rubber layer and is fixedly connected to the outer side of the film layer. The pipeline main body is designed as needed and integrally machined and formed by adopting a 3D scanning and printing technology according to the tunnel structure. The anti-corrosion layer is formed by soaking the pipeline main body in a fluoride solution and transforming the fluoride solution on the inner surface and the outer surface of the pipeline main body into films. The anti-corrosion pipeline provided by the invention is high in forming speed, can well meet the use requirements, is good in corrosion resistance, ensures the project quality, improves the construction efficiency and lowers the construction cost. The complex-shaped anti-corrosion pipeline is suitable for formation of complex-shape anti-corrosion pipelines for special tunnel structures.

Description

technical field [0001] The invention belongs to the technical field of metal pipeline anticorrosion structure forming, and relates to an anticorrosion pipeline structure and a forming method thereof, in particular to a complicated shape anticorrosion pipeline for a special tunnel structure and a forming method thereof. Background technique [0002] Anti-corrosion pipeline refers to the anti-corrosion process, which can effectively prevent or slow down the chemical or electrochemical reaction corrosion of liquid or gas materials in the process of transportation and use. Most of the anti-corrosion pipelines are located in complex soil environments, and the transported media are also corrosive, so the inner and outer walls of the pipeline may be corroded. Once the pipeline is corroded and perforated, it will cause material leakage, which will not only interrupt the transportation, but also cause pollution. environment, and may even cause a fire, causing hazards. [0003] The l...
