Description

Technical Field

[0001] The utility model relates to the technical field of roadbed widening, in particular to a roadbed structure for widening and splicing a new roadbed with an old one. Background Art

[0002] With the rapid development of social economy, people's quality of life is constantly improving, and the number of vehicles is also increasing. However, some old roads cannot meet traffic requirements, and the saturation of traffic load has also caused some sections to reach the end of their service life ahead of schedule. In order to ease traffic pressure and improve the traffic capacity of roads, one is to build new high-grade highways on a large scale, and the other is to expand and renovate existing highways; therefore, widening and expansion are often required, but cracks, faults and local collapses often occur at the junction of the new and old roadbeds. After the existing expanded highways have been in use for a period of time, the new and old road surfaces are prone to deformation, and settlement is prone to occur due to the difference in strength, which can seriously cause the road surface to crack. Therefore, a roadbed structure with widened and spliced ​​new and old roadbeds is proposed.

[0003] However, the prior art lacks a quick installation function. In actual use, workers need to spend a lot of time installing and fixing the new and old roadbeds, which reduces the work efficiency of the workers and increases their workload.

[0004] In addition, the prior art lacks drainage and waterproofing functions. In actual use, it is impossible to effectively drain rainwater and prevent leakage, which causes troubles, so that the roadbed is soaked by rainwater for a long time, affecting the safety of the roadbed.
