[0002] The main function of municipal pipelines is to transport and discharge water. Over time, a large amount of sludge, debris and sediment will accumulate in the pipelines. These substances will reduce the effective diameter of the pipelines, affect the water flow rate, and even cause pipeline blockages, leading to urban waterlogging. At the same time, the accumulated sludge and debris will produce harmful gases, such as hydrogen sulfide, which not only pollutes the environment, but may also cause explosions and fires. In addition, blocked pipelines will cause sewage overflows, pollute soil and water sources, and have a serious impact on the ecological environment.
