Embodiment 1

[0025] like Figure 1 to Figure 3 As shown, an auxiliary device for connecting a pipeline to an inspection well includes a well body 1 and a corrugated pipe body 3. At least one connection hole is opened on the well wall 2 of the well body 1, and the pipe body 3 is located in the connection hole. Between the pipe body 3 and the connection hole, there is an expansion sealing water stop ring 5, on which the expansion sealing water stop ring 5 is provided with an annular groove 6, which is clamped and sealed with the connection hole, and the expansion sealing water stop in the well body 1 The outer wall of the port of the ring 5 is bent toward the inner wall of the expansion sealing water stop ring 5 to form a notch 7, the notch 7 is tightly fitted with the end of the pipe body 3, and the pipe body 3 is provided with an expansion sealing water stop ring 5 mutually. Locked locking assembly, the inner wall of the expansion sealing water stop ring 5 is provided with an arc surface 4...

Abstract

The invention discloses an auxiliary device for connecting a pipeline and an inspection well. The auxiliary device comprises a well body and a corrugated pipe body, at least one connecting hole is formed in the well wall of the well body, the pipe body is located in the connecting holes, an expansion sealing water stop ring is arranged between the pipe body and each connecting hole, an annular groove is formed in each expansion sealing water stop ring, the annular grooves and the connecting holes are clamped and sealed, after the outer wall of a port of each expansion sealing water stop ring in the well body is bent towards the inner wall of the expansion sealing water stop ring, a gap is formed, the gaps are tightly clamped and attached to the end of the pipe body, and a locking assembly used for mutual locking with the expansion sealing water stop rings is arranged on the pipe body. The problem that when water flow is too large, the pipeline and the inspection well are not stably connected due to the fact that the water flow scours foreign matters to impact the pipeline is solved.

Description

technical field [0001] The invention relates to the technical field of municipal construction, in particular to an auxiliary device for connecting a pipeline to an inspection well. Background technique [0002] At present, in the construction of municipal pipelines, traditional pipelines and inspection wells are generally connected together by two methods. One method is to directly pour the pipeline and the inspection well together with concrete. The other method is, Use mortar to seal the connection between the pipeline and the inspection well, but because the materials between the pipeline and the inspection well are different, or because the pipeline and the inspection well are not poured at one time, it is difficult to combine them together, making The junction between the pipeline and the inspection well is cracked, and the connection between the pipeline and the pipeline is not tightly sealed, and there will be leakage of varying degrees, resulting in sewage leakage, o...
