[0002] With the development of modern society and the improvement of people's quality of life, the requirements for water use have greatly increased. In order to prevent sewage from overflowing in the city, causing waterlogging and polluting the environment, the municipal government will bury sewage pipelines underground in the city to transport urban sewage to sewage treatment plants for sewage treatment, and then discharge it after meeting the standards.

[0003] Bellows are used in many industries, mainly for conveying liquids. Flexible and pressure-resistant pipes such as stainless steel bellows are widely used in many pipe extensions or equipment connections, etc., in the process of municipal sewage transportation and treatment. Since municipal sewage often contains silt and other dirt, it is easy to accumulate on the pipe wall and bottom during transportation in the pipe, causing pipe blockage.

[0004] For example, Chinese patent document CN117847321A discloses a high-strength pipe, including a pipe body, the pipe body including a pipe wall, the pipe wall is composed of a plurality of straight walls and curved walls connected alternately, the straight walls are arranged opposite to each other, and the curved walls are arranged opposite to each other; the outer periphery of the pipe body is sleeved with a plurality of convex rings to form a corrugated structure. For example, when using a corrugated pipe of the type of application, silt is easily accumulated on the pipe wall and the bottom of the pipe, resulting in pipe blockage. Utility Model Content

In the present embodiment, the interface portion 1 and the pipe body portion 2 are integrally formed. The interface portion 1 and the pipe body portion 2 can also be connected together by bonding, welding, melting connection, etc. as needed. The two can be sealed and watertight after being connected. Among them, the interface portion 1 includes a first connecting plate 11, which is directly connected to the pipe body portion 2. The first connecting plate 11 is thinner than the pipe body portion 2. The outer wall of the first connecting plate 11 is aligned with the outer wall of the pipe body portion 2. The part of the pipe body portion 2 that extends inward from the first connecting plate 11 forms a step surface 12. When the two corrugated pipes are connected together, the step surface 12 can act as a limiter, thereby preventing the corrugated pipe from being over-inserted and causing damage to the pipeline.

[0037] In this embodiment, one end of the first connecting plate 11 is connected to the tube body 2, and the other end is connected to the slot 13. When two bellows are connected together, the corrugated structure 21 on one of the bellows can be embedded in the slot provided on the slot 13, so that the two bellows are fixedly connected and not easy to fall off. The other end of the slot 13 is connected to the second connecting plate 14, and the end of the second connecting plate 14 is provided with a flange 15. The second connecting plate 14 and the flange 15 of this embodiment form a flaring structure, which is easier to align when connecting the two bellows, and facilitates the insertion of the bellows.

In this embodiment, the lower ends of the first inner side wall 231 and the fourth inner side wall 234 are connected by the third inner side wall 233, and the third inner side wall 233 is an arc-shaped wall, and the arc top faces the outside of the corrugated tube. The upper ends of the first inner side wall 231 and the fourth inner side wall 234 are connected by the second inner side wall 232. The first inner wall 231 is connected to the second inner wall 232, the second inner wall 232 is connected to the third inner wall 233, the third inner wall 233 is connected to the fourth inner wall 234, the fourth inner wall 234 is connected to the first inner wall 231, and the four inner walls are connected to form a pipe with a roughly trapezoidal cross section. At the same time, arc walls 235 are set at the connection points of the four inner walls as a transition of connection, and the top of the arc wall 235 faces the outside of the corrugated pipe. In this embodiment, the first inner wall 231, the second inner wall 232 and the fourth inner wall 234 can all be arc walls or straight walls. When they are arc walls, the top of the arc can face the inside of the pipe or the outside of the pipe.

[0039] Combination Figure 4In this embodiment, the outer wall of the tube wall 23 includes a pair of first outer side walls 211 and a pair of second outer side walls 212, which are arranged opposite to each other. The first outer side walls 211 and the second outer side walls 212 are connected to each other to form the outer wall of the tube wall 23. At least one of the first outer side walls 211 and the second outer side walls 212 is provided with an inner concave corner 213 at the connection point.
