Space cable structure self-anchored suspension bridge main cable erecting method
The invention discloses a main cable erecting method for a self-anchored suspension bridge with a space cable structure, which comprises the following steps of: pulling a cable strand, lifting and transversely moving the cable strand, shaping the cable strand, putting the cable strand into a saddle, tightening the cable strand and converting a main cable system, based on the space cable structure system of the self-anchored suspension bridge, adopting five pairs of temporary slings and two main towers in a midspan, separating the main cable, and arranging the main cable in the middle span; then the slings are tensioned in batches from the side of the tower column to the midspan direction of the midspan, the main cable is separated, after the main cable is separated in place, the permanent cable clamp and the slings are installed and tensioned, the angle of the permanent cable clamp is adjusted step by step according to a monitoring instruction through cooperation of a steel wire rope and a chain block, system conversion is conducted, and system conversion from the plane of the main cable of the self-anchored suspension bridge to the space is achieved. And the problem of space linetype formation of the main cable is solved.
本发明公开了一种空间缆索结构自锚式悬索桥主缆架设方法，包括索股牵引，索股提升和横移，索股整形，索股入鞍，索股紧缆，主缆体系转换，基于自锚式悬索桥空间缆索结构体系，中跨采用5对临时吊索，和2个主塔，将主缆分开，然后自塔柱侧向中跨跨中方向分批次张拉吊索，将主缆分开，主缆分开到位后，安装永久索夹和吊索并张拉，采用钢丝绳配合手拉葫芦按照监控指令逐步调整永久索夹角度，进行体系转换，实现自锚式悬索桥主缆平面到空间的体系转换，解决了主缆空间线型形成的难题。
