Extra-large half-through arch bridge suspender replacement construction method
The invention discloses a extra-large half-through arch bridge suspender replacement construction method. The construction method comprises the steps: 1, conducting construction preparation; 2, determining the length of a new suspender; 3, installing a temporary suspender system; 4, installing the new suspender, and converting suspender force; 5, dismantling the temporary suspender system; and 6,mounting a suspender accessory component. Compared with the existing construction technology, the stress states of the bridge floor structure and the arch rib structure are unchanged before and afterconstruction and in the construction process, and the linearity of the bridge flooris almost unchanged. The technology is simple, construction procedures are few, the construction period is short, andinfluences on traffic are small; the selection of the new suspender considers the possibility of replacing the suspender again, and the replaceable new suspender is adopted, so that the next suspender replacement is facilitated.
本发明公开了一种特大中承式拱桥吊杆更换施工方法，包括步骤：步骤1：施工准备；步骤2：确定新吊杆长度；步骤3：临时吊杆体系安装；步骤4：新吊杆的安装及吊杆力的转换；步骤5：临时吊杆体系拆除；步骤6：吊杆附属构件安装。与现有施工技术相比，在施工前后及施工过程中，桥面结构、拱肋结构受力状态不变，桥面线性几乎不变。技术简单，施工工序少，工期短，对交通影响较小；新吊杆的选择考虑了吊杆再次更换的可能性，采用可更换式新吊杆，方便了下次吊杆的更换。
