[0002] At present, with the rapid development of urban infrastructure construction, pipe jacking construction is increasingly widely used in underground projects, successfully solving the problem of pipeline construction. Pipe jacking construction reduces a lot of preliminary work, including building demolition and enclosure, public pipeline relocation and enclosure, etc., and also reduces the pressure on the already busy urban traffic. It is a municipal engineering construction method that has developed very rapidly in recent years. It does not have to be restricted by surface buildings and the surrounding environment, making construction more convenient. Pipe jacking is a non-excavation construction technology. Its main principle is to push the prefabricated pipe section into the stratum through the back jack, thereby forming the tunnel required for construction. Generally speaking, the prefabricated pipe section is used for jacking, and the formed tunnel is assembled from longitudinally continuous pipe sections of a certain width.

[0003] The existing anti-seepage jacking pipes lack certain protective equipment at the joints during use, and are easily damaged or broken due to external factors during use after installation, resulting in cracks inside the joints and water flowing inside the jacking pipes seeping in. On the other hand, long-term use may also cause rust at the joints due to the lack of protection, and long-term use cannot be guaranteed. Therefore, a new anti-seepage jacking pipe is designed to solve the above problems. Utility Model Content
