The general construction procedure of building pipeline engineering is: "construction preparation → reservation and embedding → pipeline mapping and setting out → pipeline element inspection → pipeline support fabrication and installation → pipeline processing and prefabrication → pipeline installation → system test → anti-corrosion and thermal insulation → system cleaning → trial operation → completion acceptance". Among them, pipeline system test is an essential step before completion acceptance, and there are five major steps according to the specification requirements

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
