[0002] Plastic drain pipe is a pipe used to discharge rainwater and wastewater. It is made of plastic material and usually has a long service life and low maintenance cost. Compared with traditional metal or concrete pipes, plastic drain pipes have advantages in weight, installation speed and corrosion resistance, so they are widely used in many countries. Inspection wells are usually a facility used to collect and treat sewage. They usually consist of one or more pipes that can be discharged to a centralized treatment plant or used as recycled water. In some places, inspection wells can also be used as emergency water storage points or as part of stormwater management. Drain pipes and inspection wells need to use sealed connection devices when connected.

[0003] The patent document with announcement number: CN204343330U discloses "a plastic drain pipe and inspection well sealing connection device". The utility model has a simple structure, compact design, easy use, good waterproof sealing, high ring stiffness, strong deformation resistance, good quality stability and long service life. The outer steel casing can be directly cast at the well wall interface to avoid the construction inconvenience caused by the reserved interface of the inspection well and the weakening of the well body structure strength. It is more suitable for the connection between large-diameter plastic drain pipes and inspection wells. However, the outer steel casing and the inner lining steel pipe in the above-mentioned device need to be fixed to the inside of the inspection well with bolts, and it is necessary to enter the inside of the inspection well for installation, which is inconvenient to operate and has low work efficiency. Therefore, it is necessary to provide a plastic drain pipe and inspection well sealing connection device to solve the above-mentioned technical problems. Utility Model Content
