[0002] With the development of urbanization, people have also put forward requirements for various urban developments. Among them, urban underground drainage has also received widespread attention, because the importance of urban drainage directly affects the operation of the entire city, and the sewage on the urban ground can flow from the drain outlet into the PE multi-rib corrugated pipe installed underground, and then drain through the corrugated pipe. The PE multi-rib corrugated pipe is also called the PE inner rib corrugated pipe. The PE multi-rib corrugated pipe is an efficient and reliable drainage and sewage pipe, which is widely used in municipal engineering and underground buried drainage and sewage in residential areas.

[0003] In the prior art, general corrugated pipes are only wrapped with a reinforcing rib on the outside, and the surface without the reinforcing rib is likely to be damaged by excessive force after contacting the soil, and there are no stable supporting ribs in the reinforcing ribs of the pipe to assist the reinforcing ribs in protecting the pipe, which leads to a decrease in the overall rigidity of the pipe, thereby affecting the drainage effect. Although the PE multi-rib corrugated pipe itself has a certain degree of corrosion and acid resistance, with the current increasingly serious pollution, the corrugated pipe will be corroded faster, thereby affecting the service life of the corrugated pipe.
