Description

Technical Field

[0001] The utility model relates to the technical field of municipal transportation, in particular to an improved abandoned inspection well within a driving lane. Background Art

[0002] Abandoned inspection wells refer to inspection wells in municipal engineering or industrial pipeline systems such as water supply and drainage, gas, and heat that are no longer used due to line adjustments, system modifications, regional planning changes, etc.; the inspection wells are abandoned due to engineering modifications, regional function changes, and technological upgrades. The abandonment of inspection wells leads to a series of problems. For example, changes in groundwater levels or subsidence of surrounding soil may damage the structure of the abandoned inspection wells. Once a collapse occurs, it may cause ground subsidence, posing a danger to pedestrians and vehicles.

[0003] Deficiencies of existing technology:

[0004] At present, the measures taken to deal with the safety hazards caused by the abandonment of inspection wells usually result in a large waste of manpower and material resources. Conventional landfill treatment has the risk of insufficient compaction and subsequent road subsidence. At the same time, rainwater backflow may cause road subsidence. Utility Model Content

[0005] The purpose of the utility model is to provide an improved abandoned inspection well in the range of a driving lane to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an abandoned inspection well for improving a driving lane, comprising an original pavement layer, the inspection well being arranged below the original pavement layer, the inspection well being provided with a reinforcement structure, the reinforcement structure comprising:

[0007] A silt solidified soil layer, the silt solidified soil layer being arranged at the bottom of the inspection well;

[0008] A reinforced concrete cover plate, the reinforced concrete cover plate being arranged on the top of the inspection well;

[0009] A concrete base layer is arranged above the reinforced concrete cover plate.

[0010] Preferably, the width of both sides of the concrete base is 50 to 80 cm greater than the width of both sides of the reinforced concrete cover plate.

[0011] Preferably, a semi-rigid base layer and an asphalt layer are provided above the concrete base layer.

[0012] Preferably, steps are provided between the semi-rigid base layer and the asphalt layer, between the asphalt layer and the concrete base layer, and between the concrete base layer and the reinforced concrete cover plate, and fiberglass grilles are provided on top of the steps.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This type of improved abandoned inspection well within the driving lane is provided with a reinforcement structure, which includes a silt solidified soil layer, a reinforced concrete cover plate and a concrete base layer. Quick-hardening cement is sprayed on the rainwater and sewage pipes inside the inspection well to improve construction safety. The silt solidified soil layer is backfilled, which not only reduces the waste of resources but also improves the roadbed compaction quality. The concrete base layer is laid on the reinforced concrete cover plate, which effectively reduces stress concentration and improves the durability of the road surface.

[0015] This type of abandoned inspection well in the carriageway area can reduce the occurrence of reflective cracks by installing steps between the semi-rigid base layer and the asphalt layer, between the asphalt layer and the concrete base layer, and between the concrete base layer and the reinforced concrete cover plate.
