With the rapid improvement of people's living standards, especially the change of urban residents' lifestyle, the pressure of urban underground pipelines is also increasing. The original pipe diameter becomes smaller due to long-term pipe sludge and rust solidification, which can not meet the stable flow of discharge flow. The sludge deposit at the bottom of the pipe always raises the downstream of the drainage pipe, resulting in a decrease in the slope of the pipe, a flat flow rate, pipe blockage and double discharge
