[0002] The drainage system is an important part of municipal construction. A good drainage system can ensure the convenience of residents' lives and smooth traffic. The quality of the drainage system depends on the joint action of sewer wells, drainage pipes, and sewers. Since the drainage pipes occupy a large area and are long in length in the drainage system, the drainage performance of the drainage pipes has a vital impact on the quality of the drainage system. During the daily use of municipal pipelines, it is easy to be affected by external dirt and sedimentation over the years, resulting in blockage of the drainage pipes, which affects the drainage of the drainage pipes and affects the daily life and production of citizens.

[0004] but:

[0005] During the drainage process, garbage mixed in the water may clog the drain pipe. This phenomenon is generally concentrated in the curved section of the drain pipe. The drainage capacity of the blocked drain pipe drops sharply and cannot meet the drainage requirements. After the curved drain pipe is blocked, it usually needs to be manually dismantled for unblocking, which is very inconvenient. The installation structure of some municipal drain pipes is also relatively complicated. Utility Model Content
