Waterproof jacking pipe

Abstract

The invention relates to the technical field of pipeline construction, in particular to a waterproof jacking pipe. The pipe comprises unit pipes connected in an inserted manner, the two ends of each unit pipe are provided with a bell mouth and an inserting mouth respectively, and prestress devices are arranged at the ends, close to each other, of the unit pipes and comprise steel wire ropes and locking assemblies. A first scarf joint groove is formed in the end, close to each inserting mouth, of each unit pipe, a second scarf joint groove is formed at the end, close to each bell mouth, of each unit pipe, one end of each steel wire rope is arranged on the front unit pipe in a penetrating manner, one locking assembly is located in the first scarf joint groove, the other end of each steel wire rope is arranged on the rear unit pipe in a penetrating manner, and the other locking assembly is located in the second scarf joint groove. The waterproof jacking pipe has the following effects that the prestress devices are used for applying prestress between the two unit pipes which are connected in the inserted manner, so that the two adjacent unit pipes can be kept coaxial all the time in the jacking process, the connectivity between the unit pipes is not easy to affect, and then the waterproof effect between the unit pipes can be guaranteed.

Description

technical field [0001] The present application relates to the technical field of pipeline construction, in particular to a waterproof pipe jacking. Background technique [0002] Pipe jacking is a pipeline that is buried using trenchless construction techniques. Trenchless construction technology is a pipeline burying technology that does not excavate or excavates less. During pipe jacking construction, it is necessary to rely on the jacking force generated by jacking equipment (such as jacks, etc.) to overcome the frictional resistance between the pipe and the surrounding soil, and push the pipe into the foundation according to the designed slope. [0003] Pipe jacking has the advantages of less impact on the surrounding environment, small construction area, and low noise. It solves the problems of damage to roads and buildings during pipeline burying construction, and highlights its advantages in stabilizing the soil layer and environmental protection. Therefore, Pipe jac...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that during the jacking process of two adjacent pipe bodies, if the axis lines of the adjacent two pipe bodies are not aligned, it is easy to affect the mutual cooperation of the two adjacent pipe bodies. The connection effect between the socket and the socket will cause damage to the socket and the socket in severe cases, resulting in poor waterproof effect of the pipe body
