Isolation plate used for road construction and road construction method of isolation plate

Abstract

The invention discloses an isolation plate used for road construction and relates to the field of traffic engineering. The isolation plate is used for isolation a bearing platform and a roadbed. The isolation plate comprises a first base plate body and a second base plate body. The first base plate body is used for being connected with the bearing platform, and the second base plate body is used for being connected with the roadbed. Meanwhile, the first base plate body and the second base plate body can slide relatively. According to the isolation plate used for road construction, the bonding force between the roadbed and the bearing platform can be released, the restraint of the bearing platform on settling of the nearby roadbed is reduced, the phenomenon that the road surface near the bearing platform is bulged seriously is avoided, the bearing platform does not need to be deeply buried, the cost is saved, and the construction difficulty is lowered.

Description

technical field [0001] The invention relates to the field of traffic engineering, in particular to an isolation board for road construction and a road construction method thereof. Background technique [0002] In traffic engineering, viaduct bridges are usually erected on caps, and roadbeds are set around the caps for vehicles to walk on. For the safety of the elevated bridge, the foundation piles of the bridge cap are stable and there is almost no settlement. However, the soil settlement at the bottom layer of the soft soil subgrade is relatively large, up to tens of centimeters. There is a strong bonding force between the platforms, which leads to serious restrictions on the settlement of the subgrade, especially the settlement of the road surface near the caps, which leads to bulges on the subgrade and road surface, which seriously affects the safety of vehicles.

AI Technical Summary

Problems solved by technology

For the safety of the elevated bridge, the foundation piles of the bridge cap are stable and there is almost no settlement. However, the soil settlement at the bottom layer of the soft soil subgrade is relatively large, up to tens of centimeters. There is a strong bonding force between the platforms, which leads to serious restrictions on the settlement of the subgrade, especially the settlement of the road surface near the cap platform, which leads to bulges on the subgrade and road surface, which seriously affects the safety of vehicles.

[0003] In the prior art, in order to alleviate the above-mentioned bulging phenomenon of the road surface, the cap is deeply buried, and a thick layer of soil is filled on the cap. The thickness of the soil reaches about 1.5m. When the soft soil subgrade settles, the distance between the deeply buried cap The road surface is far away, and the force that restricts the road surface settlement becomes dispersed. This approach does not actually eliminate the road bumps, but only expands the range of the bumps, reduces the height of the bumps, and slightly alleviates the hazard of car jumping

Moreover, in order to bury the cap deeply, it is necessary to increase the excavation depth of the foundation pit in soft soil, which requires higher requirements for the cap support structure, which will not only greatly increase the project cost, but also increase the difficulty of cap construction and slow down the construction progress
