Construction method for replacing stay cable of long-term service steel cable-stayed bridge
The invention discloses a construction method for replacing stay cables of a long-term service steel cable-stayed bridge. The construction method comprises the steps that a measuring point is installed, specifically, old cable dismantling comprises old cable force releasing, old cable beam end anchoring dismantling and old cable tower end anchoring dismantling, and new cable installing comprises new cable transporting, tower end hanging, beam end installing and anchoring and new cable force tensioning. In the replacement process, temporary cables are not arranged, and the cables are unloaded and tensioned one by one, so that the risk of safety accidents of the bridge in the cable replacement process is reduced, the bridge cable replacement construction speed is increased, the construction safety is ensured, and the construction management cost is reduced.
本发明公开了一种用于长期服役钢斜拉桥斜拉索更换的施工方法，包括：测点的安装，其中旧索拆除包括旧索索力放张，拆除旧索梁端锚固，拆除旧索塔端锚固，新索安装包括新索运输、塔端挂设、梁端安装并锚固和新索索力张拉。本发明更换过程中不设临时索，逐对卸载和张拉，降低了换索过程中桥梁发生安全事故的风险，加快了桥梁换索施工的速度，保证了施工的安全，降低了施工的管理成本。
