Method for replacing suspender of tied-arch bridge
The invention discloses a suspender replacement method for a tied-arch bridge. The method comprises the following steps: (1) arranging a temporary facility at the joint of the upper end of an original suspender and an arch rib; (2) arranging an anchoring structure at the joint of the lower end of the original suspender and the beam body; (3) a temporary suspender is lifted, so that the original suspender is in an unstressed state; (4) removing the original suspender; removing the upper end of the original suspender by using automatic loading and unloading equipment; (5) installing a new suspender; (6) adjusting a new suspender; and (7) the suspender is replaced, and the temporary suspender and temporary facilities are dismantled. According to the method, damage to the tied-arch bridge structure can be avoided, the stress condition of the suspender is improved, and later suspender replacement is facilitated; the influence on the traffic of the bridge during replacement is small, the construction adaptability is good, the construction speed is high, the efficiency is high, the operation is convenient, safety and reliability are realized, and the economical efficiency is good.
本发明公开了一种系杆拱桥的吊杆更换方法，包括以下步骤：(1)在原吊杆上端与拱肋连接处设置临时设施；(2)在原吊杆下端与梁体连接处设置下锚结构；(3)提升设置临时吊杆，使原吊杆处于无应力状态；(4)拆除原吊杆；利用自动装卸设备将原吊杆的上端拆除；(5)安装新吊杆；(6)调整新吊杆；(7)完成吊杆更换，拆除临时吊杆以及临时设施。本发明的方法能够避免对系杆拱桥结构的损害，改善吊杆受力状况，便于后期吊杆更换；更换期间对桥梁的交通影响较小，并且施工的适应性好、施工快、效率高、操作方便、安全可靠、经济性好。
