Dismantling method of large-span steel strand stay cable
The invention relates to a dismantling method for a large-span steel strand stay cable, and belongs to the technical field of bridge maintenance. The dismantling method for the large-span steel strand stay cable comprises the steps that a steel strand is tensioned through a first traction mechanism, so that the steel strand at a fixed end anchorage device is subjected to force unloading, the steel strand subjected to force unloading is cut, and the large-span steel strand stay cable is obtained; the second traction mechanism is used for tensioning the hoisted steel strand so as to unload the steel strand at the tensioning end anchorage device, the unloaded steel strand is cut, the steel strand connected with the second traction mechanism is separated from the tensioning end anchorage device, the remaining steel strand is detached, and all the detached steel strands are carried; by means of the first traction mechanism and the second traction mechanism, the situation that a complex large hanging bracket needs to be installed on the tower top, consequently, installation is inconvenient and complex, and the working efficiency is reduced is avoided, the whole steel strand is broken up into parts by cutting the steel strands at the anchorage device at the fixed end one by one and cutting the steel strands at the anchorage device at the tensioning end in a grouping mode, and the construction cost is reduced. And the hoisting risk and the hoisting cost are reduced.
本申请涉及一种大跨度钢绞线斜拉索的拆除方法，属于桥梁维修技术领域，所述大跨度钢绞线斜拉索的拆除方法，包括通过第一牵引机构对钢绞线张拉，以使固定端锚具处的钢绞线卸力，将卸力的钢绞线切割，第二牵引机构对吊装的钢绞线张拉，以使张拉端锚具处的钢绞线卸力，将卸力的钢绞线切割，使第二牵引机构所连接的钢绞线与张拉端锚具分离，将剩余钢绞线拆除，将所有拆除的钢绞线搬运；本申请可以通过第一牵引机构和第二牵引机构避免了需要在塔顶安装复杂的大型吊架，导致安装不便，安装复杂，降低工作效率，通过对固定端锚具处的钢绞线逐根切割，和对张拉端锚具处的钢绞线分组切割，使整根钢绞线化整为零，降低了吊装风险和降低了吊装成本。
