Problems solved by technology
[0003] (1) The inspection well cannot be constructed synchronously with the delamination of the subgrade and pavement structural layers;
[0004] (2) The construction period is long, and the construction of the next process can only be started after the block mortar or cast-in-place cement concrete reaches the working strength after 3 to 5 days;
[0005] (3) Backfill repair after back excavation, secondary labor and small machine tool operation, the quality is not easy to guarantee;
[0006] (4) Waste materials, excavate the newly paved roadbed and road surface structure, and generate muck and garbage

The invention relates to the technical field of town road construction and provides a prefabricated inspection well and a construction method thereof. According to the prefabricated inspection well and the construction method thereof, by carrying out reasonable arrangement on the inspection well, construction of the inspection well itself and construction of the road structure can be carried out synchronously in a layered manner without waiting for concrete block masonry mortar or cast-in-situ cement concrete to reach construction strength, so that the construction time is reduced, and the method is especially suitable for the town road quick opening requirement; since each road structure layer does not have repairing seams, and construction is carried out by large-scale machines, the road construction quality is improved; and finally, since backfill repairing after multitime digging is not needed, waste of the materials can be prevented.
Description
technical field [0001] The invention relates to the technical field of urban road construction, in particular to a prefabricated inspection well and a construction method thereof. Background technique [0002] Inspection wells are generally arranged on roads in cities and towns. Back excavation is done after the subgrade or pavement base and cushion are constructed, and masonry is used to build or install prefabricated modules or cast-in-place reinforced concrete. Among them, the traditional practice of prefabricated concrete assembly inspection well is as follows: figure 1 As shown, it includes the following steps: excavation of foundation pit of inspection well → installation or cast-in-place inspection well chamber floor → masonry or installation or cast-in-place inspection well chamber wall → masonry or installation or cast-in-situ inspection well chamber, Laying connecting pipes → masonry or installation or cast-in-place inspection well chamber, installation or cast-in...
