[0002] In municipal engineering, the combined construction of rainwater pumping stations and regulating reservoirs to play their roles together has become a current development trend. The regulating reservoir is mainly used to collect and store rainwater, which can effectively reduce the burden on the urban drainage system. The integrated vacuum flushing system vacuum water diversion chamber is used in the regulating reservoir, which has extremely high requirements on the air tightness of the structure. The air tightness quality plays a decisive role in the normal operation of the integrated vacuum flushing system.

[0003] Generally speaking, the leakage points of the vacuum water diversion chamber structure are mainly concentrated in the water-stop screw. The traditional water-stop screw with a water-stop ring is difficult to achieve a high water-stop and air-stop effect.

Therefore, it is difficult to solve the problem by sticking waterproof membranes or applying waterproof coatings. Utility Model Content
