Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drainage inspection well construction, in particular to a high-adaptability anti-seepage and interception integrated drainage inspection well. BACKGROUND

[0002] In municipal pipeline drainage engineering, in order to facilitate the connection of the inspection well and the drainage pipeline, the pipeline access hole reserved in the prefabricated drainage inspection well is usually larger than the outer diameter of the drainage pipeline, and the pipeline access hole is usually sealed by bricks and concrete after the drainage pipeline is inserted into the pipeline access hole of the prefabricated drainage inspection well. However, it is difficult to ensure the sealing quality of the pipeline access hole in actual application, which easily leads to the pipeline access hole becoming the main leakage point in the drainage system; secondly, the filling of the pipeline access hole is rigid, and when the foundation appears uneven settlement, the connection between the prefabricated drainage inspection well and the drainage pipeline is easily cracked, leading to leakage.

[0003] In addition, in municipal pipeline drainage engineering, new pipes are often connected to old pipes or old pipes are often maintained by cleaning, and both of these two types of maintenance require dry trench construction, but the drainage pipeline is often in a state of water flow, so when dry trench construction is required, the pipeline must be sealed. At present, the pipeline is mainly sealed by manually placing a rubber airbag in the drainage inspection well to achieve interception. In actual application, the safety is low, the operation is difficult and the efficiency is low.

[0004] Therefore, it is necessary to invent a high-adaptability anti-seepage and interception integrated drainage inspection well to solve the problems of easy leakage and difficult interception of the existing prefabricated drainage inspection well. SUMMARY

[0023] During construction, the integrated anti-seepage liner is attached to the inner wall of the square well body 101 using hooks, and the edge of the central hole 207 is fixed to the lower end of the central through hole using expansion bolts. Next, the upstream anti-seepage liner sleeve 202 extends from the upstream pipe connection port, and the downstream anti-seepage liner sleeve 203 extends from the downstream pipe connection port. Anti-wear washers are fitted on the outer surface of the penetration section of both the upstream and downstream anti-seepage liner sleeves 202 and 203, and rubber sealing rings 209 are fitted onto both washers. Then, rubber waterstop rings 211 are fitted onto the surfaces of the upstream and downstream drainage pipes 106 and 107, respectively.
