Method for positioning and erecting suspension bridge main cable prefabricated parallel cable strands based on scale cable strand
The invention discloses a method for positioning and erecting suspension bridge main cable prefabricated parallel cable strands based on a scale cable strand. The method comprises the following stepsthat: the scale cable strand is installed in a scale cable strand saddle groove base, and a saddle-entering position marking line is marked; the prefabricated parallel cable strands are transversely moved into the prefabricated parallel cable strand saddle groove base, and cable strand discharging marking lines are aligned; the height difference between the midspan position scale strand and the prefabricated parallel strands is measured; according to the height difference, the adjustment amount of the prefabricated parallel cable strands is obtained through catenary numerical solution; an in-saddle positioning mark line is marked according to the adjustment amount by taking the in-saddle position mark line as a reference; and the prefabricated parallel cable strands are transversely movedinto a saddle according to the saddle-entering positioning mark line. High-precision positioning and saddle entering of the prefabricated parallel cable strands are achieved, repeated position adjusting operation after the prefabricated parallel cable strands enter the saddle is avoided, then traction erection and positioning saddle entering of the prefabricated parallel cable strands can be synchronously conducted, and erection construction efficiency is greatly improved.
一种基于标尺索股定位架设悬索桥主缆预制平行索股的方法，包括步骤：在鞍座旁设置标尺台；将标尺索股安装在标尺索股鞍槽座内，并标明入鞍位置标记线；将预制平行索股横移至预制平行索股鞍槽座内并将索股下料标记线对齐；测量跨中位置标尺索股与预制平行索股的高度差；根据高度差，通过悬链线数值求解得到预制平行索股的调整量；以入鞍位置标记线为基准，根据调整量标明入鞍定位标记线；根据入鞍定位标记线将预制平行索股横移入鞍。本发明实现了预制平行索股高精度定位入鞍，避免了预制平行索股入鞍后的反复位置调整作业，进而可实现预制平行索股的牵引架设与定位入鞍同步进行，大幅度提高了架设施工效率。
