[0002] Drainage pipes refer to the system of pipes and their ancillary facilities that collect and discharge sewage, wastewater, and rainwater. They include main pipes, branch pipes, and pipes leading to treatment plants. Drainage pipes are one of the most effective methods for cities to deal with urban flooding. Due to various structural defects and imperfections in drainage outlets, a large amount of groundwater and other external water seeps into the pipes, and a large amount of silt accumulates inside the pipes. This situation is most common during urban flooding. Therefore, when conditions permit, we need to inspect drainage pipes to understand their internal operating status.
