Suspension bridge main cable strand multi-point transverse moving erection method through catwalk portal
The invention relates to a method for carrying out multi-point transverse movement erection on a main cable strand of a suspension bridge by using a catwalk portal. The method comprises the following steps: erecting a catwalk 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 lifting and transverse moving devices are erected on the catwalk at intervals in the bridge direction; each lifting transverse moving device serves as a lifting point position of the cable strand, and the lifting transverse moving devices of the lifting point positions transversely move to the position above the main cable after lifting the cable strand and then release the cable strand to enable the cable strand to fall into the main cable; and the steps are repeated until all the cable strands are erected. According to the method, the multiple lifting and transverse moving devices are arranged to serve as the multiple lifting point positions of the cable strand, the multiple lifting point positions lift and transversely move the cable strand in the length direction of the cable strand at intervals, the time lag effect generated when the midspan cable strand is erected is eliminated, and it is ensured that the cable strand is not loosened or twisted.
本发明涉及利用猫道门架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个提升横移装置；每个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。本发明通过设置多个提升横移装置作为索股的多个提升点位，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。
