Background
The inspection well is also called an inspection well and is generally buried underground and used for connecting various pipelines, and the pipelines can be maintained by opening a well cover when in use. Existing inspection wells are typically cast in place using concrete. The inspection well adopting the mode can be convenient for concrete construction only by carrying out large-area excavation, and the pouring process of the inspection well also needs complicated and long construction processes such as template building, pouring, maintenance, final filling and the like. The poured concrete inspection well is difficult to temporarily open a hole as required to take over, and the flexibility is poor. The concrete inspection shaft needs thicker wall thickness to reach the design structure strength, and once the conditions such as leakage damage appear in the inspection shaft, the mode that the concrete was poured again to the whole inspection shaft that often needs to destroy maintains. The inspection well is buried underground and is greatly affected by various kinds of sewage in the pipeline. The inspection well poured by the concrete has the defects of poor corrosion resistance and short service life. The inspection well made of plastic can be produced in a production workshop by prefabricating the mold, and can well overcome the defects of the concrete inspection well. However, the inspection well made of common plastics has the defects of low structural strength, easy deformation, easy aging, short service life and the like. And the on-site drilling operation of the inspection well made of common plastic is complex, and the inspection well is easy to deform and the like, so that the on-site rapid butt joint installation with a pipeline is difficult to realize. Therefore, the plastic inspection well is not widely popularized and applied at present.
