[0002] The water supply and drainage pipeline project is a pipeline system project that transports and distributes industrial water supply and drinking water, and collects, transports and discharges industrial wastewater, domestic sewage and rainwater. The water supply and drainage pipeline is an integral part of the water supply and drainage pipeline project, and plays an important role in the entire water supply and drainage system. The water supply and drainage pipeline in the water supply and drainage pipeline project is divided into main drainage pipelines and branch drainage pipelines. The main drainage pipeline is usually a pipeline with a larger diameter and a stronger load-bearing capacity. It is responsible for connecting various branch drainage pipelines and equipment. Branch drainage pipelines are usually set with different diameters and layouts according to needs, and some branch drainage pipes usually need to be anti-seepage treated.

[0003] Some existing branch drainage pipes are usually connected through flanges, and the sealing gaskets at the flange connections can seal the drainage pipes. The sealing gaskets may age or be damaged after long-term use, thereby reducing the sealing performance and causing water seepage in the drainage pipes. At the same time, the bolts at the flange connections are not tightened in place or are tightened unevenly, resulting in poor sealing and causing water seepage. Utility Model Content
