Inhaul cable positioner and bridge stay cable replacement method
The invention belongs to the technical field of engineering construction, and particularly relates to an inhaul cable positioner and a bridge stay cable replacement method. Via holes allowing the steel strands to penetrate through are formed in a positioning base of the inhaul cable positioner, the via holes and the steel strands are arranged in a one-to-one correspondence mode, and the adjacent via holes are arranged at intervals. When the inhaul cable is replaced, the tensioning force of the target steel strand 11 is released on the inner side of the structure; then the target steel strand 11 with the tensioning force removed in the step A is disassembled, and meanwhile a new steel strand 20 is dragged; and then the new steel strand 20 is tensioned, and installation of the new steel strand 20 is completed. By the adoption of the positioner, the steel strands are arranged at intervals, in this way, when the inhaul cable is replaced, an operator does not need to perform construction onthe outer side of a structure, the personal safety of the operator can be effectively improved, and meanwhile the replacement efficiency is remarkably improved.
本发明属于工程建设技术领域，特别涉及一种拉索定位器及桥梁斜拉索更换方法。拉索定位器的定位座上设有供钢绞线贯穿的过孔，过孔与钢绞线一一对应布置且相邻过孔之间间隔布置。更换拉索时，在构筑物内侧释放目标钢绞线11的张拉力；然后拆卸步骤A中卸去张拉力的目标钢绞线11，同时牵引新钢绞线20；再张拉新钢绞线20，完成新钢绞线20的安装。采用本发明的定位器使得钢绞线分别间隔布置，这样在更换拉索时，作业人员无需在构筑物外侧施工，能有效提升施工作业人员的人身安全，同时显著提升更换效率。
