| description | The invention discloses a device and a method for connecting a cast-in-place rain sewage inspection well chamber and a prefabricated concrete pipeline, relates to the technical field of a connecting process of a cast-in-place rain sewage inspection well and a prefabricated concrete pipeline, and mainly aims to solve the problem that the joint of the existing cast-in-place rain sewage inspection well chamber and the prefabricated concrete pipeline is easy to damage. The device comprises a cast-in-place rain sewage inspection well, a concrete prefabricated pipeline and a flexible intermediate layer, oil hemp asphalt, a hydrophobic plastic plate and polysulfide sealing paste in the flexible intermediate layer are annularly paved at a pipe opening of the concrete prefabricated pipeline, and waterproof mortar is wrapped at the outer end to serve as a protection layer, so that water leakage can be prevented; and the mortar further can have certain activity. When the foundation settles, the pipeline can slightly mov |
