Arched girder installation construction method of large-span arch bridge
The invention provides an arched girder installation construction method of a large-span arch bridge, and relates to the technical field of bridge construction, the arched girder installation construction method of the large-span arch bridge comprises the following steps: installing a temporary support which comprises a steel main girder assembling support, a dragging support and a main span side box support; assembling a steel main beam section on the steel main beam assembling bracket; dragging the assembled steel main beam section on a dragging bracket until the steel main beam section reaches a preset position; the steel main girder sections are assembled to a main span side box support; repeating the steps of assembling the steel main beam sections and dragging the assembled steel main beam sections, and fixing the latter steel main beam section with the former steel main beam section after the latter steel main beam section is assembled in place until the erection of the steel main beam is completed; in the installation process of the steel main beam, an arch rib installation support is erected, arch rib construction is carried out, and the closure position of arch ribs is located between the highest position and the lowest position of the arch ribs. The efficiency and universality of arched girder construction can be improved.
本发明提供了一种大跨度拱桥的拱梁安装施工方法，涉及桥梁施工技术领域，该大跨度拱桥的拱梁安装施工方法包括以下步骤：安装临时支架，临时支架包括钢主梁拼装支架、拖拉支架和主跨边箱支架；在钢主梁拼装支架上拼装钢主梁节段；在拖拉支架上拖拉拼装好的钢主梁节段，直至钢主梁节段到达预设位置；将钢主梁节段落梁至主跨边箱支架；重复拼装钢主梁节段以及拖拉拼装好的钢主梁节段的步骤，并在后一个钢主梁节段落梁到位后与前一个钢主梁节段固定，直至完成钢主梁的架设；在钢主梁安装过程中搭设拱肋安装支架，进行拱肋施工，且拱肋的合龙位置处于拱肋的最高位置和最低位置之间。本发明可提高拱梁施工的效率以及通用性。
