Description

Gas pipeline plugging structure Technical Field The application relates to the technical field of pipeline repair, in particular to a gas pipeline plugging structure. Background With the acceleration of the urban process, the urban gas demand is also increasing, and the number and the length of gas pipelines are also increasing, however, due to factors such as geological environment, town construction, improper use of users and the like, gas leakage accidents can occur in the operation process of the natural gas pipelines. The traditional pipeline repairing method is to carry out depressurization and diffusion operations on the pipe section where the leakage pipeline is located, then carry out construction operations such as fire cutting, welding, drilling and the like, and because the operation pipeline is provided with fuel gas with certain pressure and concentration, a plurality of potential safety hazards are inevitably brought to operators in construction, and meanwhile, the environment is polluted. Disclosure of utility model The embodiment of the application aims to provide a gas pipeline plugging structure which improves the reliability and safety of a gas pipeline. The embodiment of the application provides a gas pipeline plugging structure, which adopts the following technical scheme: The utility model provides a gas pipeline plugging structure, includes repairing agent layer, first inoxidizing coating and reinforcement layer, repairing agent layer is used for the leak point of shutoff pipeline, first inoxidizing coating twines in the outside of pipeline, first inoxidizing coating covers repairing agent layer, be provided with the binder layer between first inoxidizing coating and the pipeline, the reinforcement layer sets up the outside of first inoxidizing coating. Preferably, the plugging structure further comprises a second protective layer, the second protective layer comprises a waterproof adhesive tape and two rubber gaskets, the waterproof adhesive tape covers the first protective layer and the reinforcing layer, the rubber gaskets are arranged on the outer wall of the pipeline, the first protective layer is located between the two rubber gaskets, and the end part of the waterproof adhesive tape is connected with the rubber gaskets. Preferably, the repairing agent layer is made of a rapid steel glue stick. Preferably, the first protective layer is formed by winding a plurality of layers of glass fiber cloth, and an adhesive layer is arranged between two adjacent layers of glass fiber cloth. Preferably, the adhesive layer is an epoxy resin liquid. Preferably, the reinforcing layer is a strapping.
