Construction plan of precast reinforced concrete assembly inspection well

The construction process of the prefabricated reinforced concrete inspection well is: construction preparation → foundation pit excavation → foundation treatment and cushion laying → inspection well installation → pipeline and inspection well connection → runner construction → pavement well circle and manhole cover installation → backfill → acceptance .

For the construction of open-slot drainage pipelines, the method can be constructed by running down the pipe section by section after slotting and hoisting in the well; it can also be constructed by preserving well positions, running down the pipe 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 grooving and hoisting the well chamber, and then jacking the pipe body into the reserved hole of the well chamber for construction. Regardless of the construction method used, in order to achieve the effect of uniform bearing of the foundation, the prefabricated concrete drainage inspection well must be pre-laid with a 5-10cm thick sand and gravel cushion under the bottom of the well chamber. Each part of the prefabricated concrete drainage inspection well is designed as a tongue and groove, and the waterproof mortar "seat slurry" is used when hoisting. Prefabricated concrete drainage inspection wells and pipelines are rigidly connected by pre-holes and filled with waterproof mortar around them. The differential settlement between the pipeline and the well body is resolved by the deformation of the flexible interface between the first and second pipe sections.

By avoiding the use of clay brick masonry and on-site wet concrete work, the work efficiency has been significantly improved. The soil can be returned after the rapid closed water pressure test, which can be done while excavating, laying pipes, installing wells, returning soil, and repairing roads. The overall performance of the prefabricated concrete drainage inspection well is good, and the connection effect with the pipeline is good, and the overall quality of the drainage pipeline is also improved.
