[0002] A traction pipe is a pipe that can cross railways and highways. Generally, a cement casing or steel casing is installed under the roadbed, and the traction pipe is pulled through the casing to ensure the safety of the pipe, railways, and highways. It is particularly suitable for municipal water supply and drainage, electricity, communications, gas pipelines and other projects, and is especially suitable for crossing rivers, railways, and densely built-up areas.

[0003] During the construction of the directional drill traction pipe, it is necessary to dig a trench pit on the ground. After the hole is opened, the soil at the hole often collapses due to the soft soil at the hole. Therefore, the entrance and exit of the directional drill need to be reinforced.

[0004] The current reinforcement method is reinforced concrete grouting reinforcement. The steel bars need to be bent and shaped before grouting to ensure a stable pouring effect, and then the steel bars need to be driven into the ground. A lot of time is required before and after construction to build and disassemble the steel bars and formwork, and then pouring. The construction process is relatively cumbersome, affecting work efficiency. Summary of the invention
