They are mainly used by maintenance workers to regularly inspect and dredge pipes, It is one of the underground infrastructures of urban roads to prevent sludge and foreign matter and prevent pipeline blockage. Due to the light weight and corrosion resistance of plastic drainage pipes and plastic inspection wells, the rigidity of pipe rings can be designed according to needs, the joints are well sealed, and there is no leakage, which can effectively prevent groundwater pollution, and the construction speed, hydraulic conditions, and cost performance are excellent. It is used in cement drainage pipes and lime-sand brick inspection wells, so it is widely used in rainwater drainage systems such as municipal roads and construction areas. The plastic inspection well socket is a fitting for the inspection well to connect pipelines of different diameters, directions, and heights. It must be connected to the well base of the inspection well and to the plastic pipe. Most of the connection between the socket and the well seat of the inspection well is an integral forming structure and a flange connection structure. The connection between the socket and the plastic pipe has a one-way socket elastic seal connection, a two-way socket elastic seal connection, a seal connection at the socket, a socket electric fusion welding connection, a hot-melt butt welding connection, a V-welding connection, a thermal Shrink sleeve connection, electric heating belt connection and flange connection. Different types of plastic pipes, such as double-wall corrugated pipe, three-layer sandwich pipe, annular ribbed pipe, double-wound flat wall and wound spiral pipe, have the same specification, and often have different socket outer diameters, and the error is large.
