PVC (polyvinyl chloride) pipeline with anti-leakage structure

The utility model discloses a PVC (polyvinyl chloride) pipeline with an anti-leakage structure, relates to the technical field of PVC pipelines, and aims to solve the problems that the viscosity of the joint of the conventional PVC pipeline is easy to reduce along with the increase of service time, so that internal water leaks and the use of a user is influenced, and the conventional pipeline is not easy to leak after glue is not adhered. And only the PVC pipeline can be dismounted from the inside for coating and remounting operation, the pipeline is easily damaged in the process, and then the leakage risk is increased. A leakproof combined connecting pipe is arranged between the PVC pipeline bodies in an interference fit manner; the injection openings are integrally formed in the upper end and the lower end of the outer wall of the anti-leakage combined connecting pipe, one end of each injection opening extends into the anti-leakage combined connecting pipe, a sealing plug is arranged at the outer side end o
