[0002] Sewage refers to the discharged water from life and production that is polluted to a certain extent. Water that has lost its original use function is simply called sewage; from the perspective of the source of sewage, sewage can be defined as liquid or water carrying waste mixed with groundwater, surface water, snowstorms, etc. discharged from residential, institutional, commercial or industrial areas. Sewage has many categories, and there are also many technologies and processes to reduce the impact of sewage on the environment; according to the source of sewage, sewage can be divided into industrial wastewater, domestic sewage, commercial sewage and surface runoff; sewage pipes provide cities with industrial and domestic water, and at the same time prevent urban water resources from being polluted;

[0003] Sewage pipes include trunk pipes, branch pipes and pipes leading to treatment plants. No matter they are built on the streets or anywhere else, as long as they serve as drainage pipes, they should be counted as drainage pipes. During the use of sewage pipes, solid particulate pollutants are collected in the sewage pipes along with the sewage, and some of them will adhere to the inside of the sewage pipes as sludge, causing the sewage pipes to rust, corrode or become blocked. Therefore, the sewage pipes need to be cleaned in a timely manner. Under the existing technology, cleaning sewage pipes is a waste of time and workers' physical strength, and is inefficient, and it is impossible to clean the sewage pipes quickly.
