Curve steel beam transverse moving construction method for bridge and tunnel connecting position
The invention relates to the technical field of bridge construction, in particular to a transverse moving construction method for a curved steel beam at a bridge-tunnel joint, which is characterized in that the curved steel beam is assembled on a bridge deck of a constructed linear steel beam and then transversely moved in place, and a high pier bracket and an operation platform do not need to be erected between bridge spans, so that the material consumption is reduced, and the construction cost is reduced. The material cost and the high pier support mounting and dismounting cost are saved, the high pier support mounting and dismounting risk is avoided, the overall construction period is shortened, meanwhile, the bearing capacity of the constructed bridge deck slab is good, the risk of differential settlement of a foundation is avoided, the splicing linear quality of the curved steel beam is improved, and the construction efficiency is improved. In addition, the method is not limited by inconsistency of the radius of the tunnel curve and the radius of the steel beam, and can adapt to high-quality and rapid installation of the multi-span curve continuous steel beam at the joint of the bridge and the tunnel in the steep mountainous area.
本发明涉及桥梁施工技术领域，特别涉及一种桥隧连接处曲线钢梁横移施工方法，通过在已施工完成的直线钢梁的桥面板拼装曲线钢梁再横移到位，不需要在桥跨之间搭设高墩支架及操作平台，减少了材料使用量，节约了材料成本和高墩支架安拆成本，避免了高墩支架安拆风险，缩短了整体施工周期，同时，已施工完成的桥面板承载力好，避免了基础不均匀沉降的风险，有利于提高曲线钢梁的拼装线形质量，保证曲线钢梁的线形及结构内力满足设计要求，另外，不受隧道曲线半径与钢梁半径不一致的限制，能够适应于陡峭山区桥隧连接处多跨曲线连续钢梁的高质量、快速安装。
