Suspension bridge main cable strand multi-point transverse moving erection method through independent cables
The invention relates to a suspension bridge main cable strand multi-point transverse moving erecting method through independent cables. The method comprises the steps that a catwalk is erected below a main cable; a traction system is erected above the main cable; a plurality of cable strand rollers are arranged in the catwalk, and the traction system pulls the cable strands to move along the cable strand rollers; a plurality of cable strand bearing cables are erected on the catwalk at intervals in the bridge direction; a plurality of lifting and transverse moving devices are arranged on each strand bearing cable at intervals, the lifting and transverse moving devices serve as lifting point positions of the strands, and the lifting and transverse moving devices at the lifting point positions firstly transversely move to the position above the main cable after lifting the strands and then release the strands to enable the strands to fall into the main cable; and the steps are repeated until all the cable strands are erected. The cable strand bearing cable is arranged, the cable strand is borne by an independent cable structure in the process of being erected to the main cable, meanwhile, the multiple lifting point positions lift and transversely move the cable strand at intervals in the length direction of the cable strand, the time lag effect during midspan cable strand erection is eliminated, and it is ensured that the cable strand is not loosened or twisted.
本发明涉及利用独立索进行悬索桥主缆索股多点横移架设方法，包括在主缆的下方架设猫道；在主缆的上方架设牵引系统；猫道内布置若干个索股滚筒，牵引系统牵引索股沿索股滚筒移动；沿顺桥向在猫道间隔架设多根索股承重索；每根索股承重索上间隔设置有若干提升横移装置，提升横移装置作为索股的提升点位，多个提升点位的提升横移装置在提升索股后先横向移动至主缆的上方，然后释放索股使其落入主缆内；重复以上步骤直至完成全部索股的架设。本发明通过设置索股承重索，使索股架设至主缆过程中由独立索结构承重，同时多个提升点位沿索股的长度方向间隔提升、横移索股，消除了跨中索股架设时的时间滞后效应，确保索股不散丝，不扭转。
