Problems solved by technology

However, in the process of flattening and compacting the subgrade and laying the road surface, construction machinery not only needs to bypass the inspection well, delaying the construction progress, but also is difficult to perform uniform compaction around the inspection well, resulting in inconsistent density of the subgrade near the inspection well, which is easy to cause T

Example Embodiment

[0029] The steps of the road repairing method for setting a manhole in the present invention are:

[0030] 1. At the preset position of the pipe and cable trench 9 under the roadbed, a manhole base 1 with a circular opening is provided.

[0031] 2. Install the bottom cover 2 on the base 1 that can be detected across the roadbed 3 and the road surface 4, or install a signal transmitter on the bottom cover 2 (usually placed in the center), or use GPS, Beidou and other positioning systems Accurate positioning of the bottom cover 2 (the positioning accuracy of the civil GPS system has reached the millimeter level in theory, and the Beidou system has higher positioning accuracy in some parts of China). The installed bottom cover 2 is approximately flush with the top of the pipe and cable trench 9, and the bottom cover 2 is adapted to the base 1, so that during the flattening and compaction process in step 3, soil, sand, etc. Just fall through the gap between them;

[0032] 3. Pave the r...

Abstract

The invention relates to an inspection well, in particular to a prefabricated inspection well and a road construction method involving the inspection well. The road construction method involving the inspection well includes the following steps of (1) arranging a base with an opening, (2) installing a bottom cover on the base, wherein the position of the bottom cover can be determined, (3) normally laying a road bed and a road surface on the bottom cover, (4) prefabricating the inspection well, (5) determining the position of the bottom cover, (6) smoothly cutting the road surface until the bottom cover is exposed and taking out the bottom cover, (7) placing the prefabricated inspection well, and (8) wholly or partially replacing, maintaining and recycling the prefabricated inspection well. The road construction method has the advantages that labor and road manufacturing cost are effectively reduced, road on-site construction time is shortened, the situation that the road surface is uneven due to uneven sediment of the surrounding of the inspection well is effectively avoided, flatness of the road surface is improved, road construction quality is improved, maintenance time of the inspection well is substantially shortened, and the inspection well can be recycled.

Description

(1) Technical field [0001] The invention relates to an inspection shaft, in particular to a prefabricated inspection shaft and a road construction method related to the inspection shaft. (2) Background technology [0002] Inspection wells are wells used in the turns, branches, drops, etc. of rainwater and sewage pipes for inspection and dredging. The scientific name is inspection wells. Inspection wells buried underground for communication, electricity, tap water, etc. are also called inspection wells. The step of inspection shaft construction on the road is generally by on-site construction, builds inspection shaft, then carries out layered compaction and flattening around the inspection shaft, lays subgrade, road surface, and finally levels the road surface around the inspection shaft. However, in the process of flattening and compacting the subgrade and laying the road surface, construction machinery not only needs to bypass the inspection well, delaying the construc...
