Deep cut road three-dimensional reconstruction and extension structure and construction method
The invention belongs to the technical field of road reconstruction and extension engineering construction, and discloses a deep cut road three-dimensional reconstruction and extension structure and a construction method.The deep cut road three-dimensional reconstruction and extension structure comprises a soil retaining structure, a plurality of prefabricated steel beams are arranged on the soil retaining structure, and a newly-installed bridge deck is arranged on the prefabricated steel beams; the soil retaining structure comprises two retaining walls symmetrically arranged on road shoulders on the two sides of the deep cut highway, and a plurality of prefabricated steel beams are supported between the opposite faces of the two retaining walls. The newly-installed bridge deck comprises a prefabricated bridge deck and a cast-in-place bridge deck which are sequentially arranged. The prefabricated bridge deck comprises a plurality of prefabricated bridge deck slabs, the prefabricated bridge deck slabs are spliced, and spliced joints fall on the top faces of the prefabricated steel beams. According to the structural scheme, three-dimensional reconstruction and expansion can be achieved by fully utilizing original road line positions, the land resource requirement and a large amount of excavation work are reduced, economy and environmental protection are achieved, meanwhile, the retaining wall has the bearing structure and the slope protection function, the construction efficiency is high, the prefabricated steel beams can serve as temporary supports and permanent structures, structural characteristics are fully utilized, and the construction cost is reduced. The economic benefit is obvious.
本发明属于公路改扩建工程建设技术领域，公开了一种深挖路堑公路立体改扩建结构及施工方法，包括挡土结构，挡土结构上设置有若干预制钢梁，预制钢梁上设置有新装桥面；挡土结构包括两道对称布置在深挖路堑公路两侧的路肩上挡土墙，若干预制钢梁支撑在两挡土墙的相对面之间；新装桥面包括依次布置的预制桥面和现浇桥面；预制桥面包括若干预制桥面板，若干预制桥面板拼合设置且拼合的接缝落在预制钢梁的顶面。本发明结构方案能够充分利用原有公路线位实现立体改扩建，减少了土地资源需求和大量的挖方作业，经济环保，同时挡土墙兼顾承重结构和边坡防护功能，施工效率高，预制钢梁可作为临时支撑及永久结构，充分利用了结构特点，经济效益显著。
