The construction process of the prefabricated reinforced concrete assembly inspection well is as follows: construction preparation → foundation pit excavation → foundation treatment and cushion laying → inspection well installation → pipeline and inspection well connection → launder construction → pavement well ring and well cover installation → backfilling → acceptance .

　　For the construction of open slotted drainage pipelines, the method of laying down the pipes one by one after slotting and hoisting in the well can be adopted; it can also be constructed by reserving the well position, lowering the pipes first, and hoisting the well body last. For pipe jacking construction, it is advisable to use the method of accurately measuring the well position, first slotting and hoisting the well chamber, and then jacking the pipe body into the reserved hole of the well chamber for construction. No matter which construction method is used, in order to achieve the effect of uniform bearing of the foundation, a 5-10cm thick gravel cushion must be laid in advance under the floor of the prefabricated concrete drainage inspection well. The parts of the prefabricated concrete drainage inspection well are designed as grooves, and waterproof mortar "seating mortar" is used for hoisting. The prefabricated concrete drainage inspection well and the pipeline are rigidly connected through reserved holes and filled with waterproof mortar around them. The differential settlement of the pipeline and the well body is solved by the deformation of the flexible interface between the first and second sections of pipe.

　　Work efficiency has been significantly improved due to the avoidance of clay brick masonry and on-site wet concrete work. The soil can be returned after the rapid closed water pressure test, and it is possible to excavate, lay pipes, install wells, return soil and build roads at the same time. The overall performance of the prefabricated concrete drainage inspection well is good, and the connection effect with the pipeline is good, which also improves the overall quality of the drainage pipeline.
