[0002] The sewage pipeline inspection well is a key facility in the urban drainage system, mainly used for collecting and distributing the sewage flow to the main pipeline, and at the same time providing a passage for inspecting, maintaining and cleaning the pipeline.

[0003] However, the existing sewage pipeline inspection wells have some disadvantages. First of all, their sedimentation efficiency is usually low, and it is difficult to effectively collect and store solid particles, resulting in the accumulation of sediments and the emission of foul odors. Secondly, due to the lack of a water flow regulating device, these inspection wells cannot adjust the water flow according to the actual drainage demand, which easily causes hydraulic shock and pipeline wear. In addition, the traditional inspection wells lack a systematic gas collection and treatment mechanism, resulting in the inability to effectively collect and treat harmful gases, and there are potential hazards such as environmental pollution and safety.
