Problems solved by technology
At present, due to the poor installation of inspection wells and tools during construction, the road surface is uneven, pits appear, inspection wells are subsidence, and surrounding roads are damaged. This not only affects the effect of road use, but also brings a lot of inconvenience to vehicles. At the same time, it will cause personal injury and property loss due to the displacement, damage, subsidence and falling of the inspection well, so it is necessary to improve the installation of the inspection well.

Embodiment Construction
[0015] The present invention is implemented according to the above steps, the through hole in the middle part of the reinforced concrete well circle plate is matched with the well tool, the well circle plate is installed on the shaft building and the surrounding roadbed, and the foundation is firm. The manhole cover and the well ring of the well tool are made of ductile iron, which has high strength and a good fit of the processing surface. No noise will be generated when the vehicle passes by. The ring seat is made of reinforced concrete. The bottom surface of the well ring is fixed with nails embedded in the ring seat. In the middle, it is combined with the reinforced concrete of the ring seat, and high-strength cement grouting is used after the well tool is installed, so that the well tool and the surrounding road surface are firmly combined, and the smoothness, appearance and appearance of the road surface will not be affected by driving and rolling. Ensure the comfort of d...

The invention provides a method for mounting well tools of an inspection well on an asphalt concrete pavement. The method is characterized in that: a well drum of a road is covered by a well ring plate; plain concrete is precast on a through hole on the middle part of the well ring plate, or a steel cover is used for sealing the hole; coarse and medium particle type asphalt concrete is wholly paved, and wholly rolled by a road roller at the same time; to be careful, a position of a well hole is marked; the asphalt concrete on the well hole is removed by a drilling machine, and a hole, of which the diameter is the same as that of the well tools, is drilled; and the well hole is opened, the well tools of the combined type inspection well is mounted, and the periphery of the well tools are sealed by grouting. By the method, the asphalt pavement is smooth, beautiful, firm and, convenient in construction; and when a vehicle runs on the asphalt pavement, the noise is hardly generated, and people in the vehicle feel comfortable.
Description
Technical field: [0001] The invention belongs to a method for installing inspection well tools in urban road construction, that is, an installation method for inspection well tools on asphalt concrete pavement. Background technique: [0002] In the construction of urban roads, there are many facilities under the road surface, such as pipelines and pipelines for rainwater, tap water, sewage, gas, postal services, telecommunications, communications, electrical, optical fiber, and fire protection. The normal operation of the equipment requires frequent maintenance, and the inspection shaft set on the road is the only passage for underground maintenance. At present, due to the poor installation of inspection wells and tools during construction, the road surface is uneven, pits appear, inspection wells are subsidence, and surrounding roads are damaged. This not only affects the effect of road use, but also brings a lot of inconvenience to vehicles. Simultaneously also can cause ...
