Construction method for lifting and folding arch ribs of arch bridge
The invention discloses a construction method for lifting and closing arch ribs of an arch bridge, and relates to the technical field of bridge construction. The construction method comprises the following steps of: dividing the arch ribs into two bulk splicing arch ribs and an integral lifting arch rib; mounting a second temporary support, and splicing and hoisting the scattered and spliced arch ribs to the set position through a floating crane; mounting an overall lifting section arch rib on the second temporary support, opening a lifting channel, and integrally moving the overall lifting section arch rib to the design position; folding and welding the bulk splicing section arch rib and the integral lifting section arch rib; and after closure detection of the bulk splicing arch ribs and the integral lifting section arch ribs is normal, completing installation of the bulk splicing arch ribs and the overall lifting section arch ribs. Compared with the prior art, splicing and welding are reasonably utilized, the construction difficulty is reduced, the stage positioning precision is improved, the segment manufacturing quality is optimized, the construction cost is reduced, the construction period is shortened, and the construction quality is guaranteed.
本发明公开了一种拱桥拱肋提升合拢的施工方法，涉及桥梁施工技术领域，包括以下步骤：将拱肋分成两个散装拼段拱肋和一个整体提升段拱肋；安装第二临时支架，拼装散段拼段拱肋，并用浮吊吊至设定位置；在第二临时支架上面安装整体提升段拱肋，打开提升通道，将整体提升段拱肋整体至设计位置；进行散装拼段拱肋和整体提升段拱肋合拢焊接；散装拼段拱肋和整体提升段拱肋合拢检测正常后，完成散装拼段拱肋和整体提升段拱肋安装。与现有技术相比，本发明合理利用拼装与焊接，具有降低施工难度、提高了阶段定位精度、优化节段制造质量、缩减施工成本和工期、保障施工质量。
