[0002] A hydraulic pipe is a pipe used to transport water resources, mainly used in urban water supply, farmland irrigation, industrial water use and other scenarios. It is usually made of stainless steel, cast iron or other materials, and can withstand certain water pressure and flow requirements. The advantages of hydraulic pipes are that they have a simple structure, long service life, and easy maintenance, which can effectively solve the problem of water shortage. At the same time, compared with traditional concrete channels, hydraulic pipes perform well in preventing water leakage and evaporation, so they have a higher water resource utilization rate. Hydraulic pipes used for drainage usually have mud, garbage and other debris accumulated, causing pipe blockage. In order to ensure the normal operation of the drainage system, the pipes need to be desilted.
