[0002] The sewage pipeline system is composed of pipes for collecting and transporting urban sewage and its auxiliary structures. The sewage flows into the main pipe from the branch pipe, and then flows into the main pipe, and finally flows into the sewage treatment plant. The pipes are small to large, and are distributed like rivers, which are completely different from the circulation of the water supply pipe network. The sewage generally flows from high to low in the pipe by the difference in water level at both ends of the pipe, and the pipe does not bear pressure, i.e. it relies on gravity flow.

[0003] In the process of sewage pipe network construction, the top-pull pipe process is used for construction, and the pipe is laid in the constructed pipe hole in sequence, thereby forming a completed sewage pipeline discharge system. However, the following problems often occur during the top-pull pipe process:

[0004] 1. The outer wall and internal structural stress of the pipe are damaged due to the stretching of the pushing mechanism or the pipe pulling mechanism, affecting the service life of the pipe;

[0005] 2. Due to the factors such as the volume and weight of the pipe, a large pushing force or pulling force needs to be applied to the pipe during the top-pull construction, and the fundamental reason is that the connection surface between the top-pull mechanism and the pipe is small, and the contact points are few.
