Suspension bridge main cable strand erection restraining method
The invention discloses a suspension bridge main cable strand erecting and position restraining method which comprises the following steps that S1, the spatial positions of catwalk bearing cables, gantries and bottom beams in a catwalk system are determined, and the spatial coordinates of the catwalk system are determined; and S2, a limiting stopper is erected, and the limiting stopper is installed on the bottom beam. The catwalk system, the erected early-stage cable strand and the to-be-adjusted cable strand are integrally connected through the limiting stopper to form a whole, the position of the to-be-adjusted cable strand is controlled in the cable strand erecting process, and due to the fact that the rigidity of the catwalk system and the rigidity of the erected early-stage cable strand are larger than the rigidity of the to-be-adjusted cable strand, the cable strand can be adjusted. The transverse position of the cable strand to be adjusted can be effectively limited through the limiting device by using the catwalk system and the overall rigidity of the erected early-stage cable strand, and the relative position of the cable strand to be adjusted and the erected early-stage cable strand can still be measured in the windy weather. The defect that in the prior art, the cable strand erecting efficiency is low due to the fact that the cable strand erecting process is prone to being affected by wind power is overcome.
本发明公开了一种悬索桥主缆索股架设抑位方法，所述抑位方法包括如下步骤：S1：确定猫道系统中的猫道承重索、门架、底梁各构件的空间位置，确定猫道系统的空间坐标；S2：架设限位器，将限位器安装在底梁上。本发明通过限位器将猫道系统与已架设的前期索股和待调索股整体联系起来，构建成一个整体，在索股架设过程中对待调索股的位置进行控制，由于猫道系统和已架设前期索股刚度大于待调索股，通过限位器利用猫道系统和已架设的前期索股的整体刚度，可有效的限制待调索股的横向位置，在大风天气下仍然能够进行待调索股和已架设前期索股相对位置测量。即实现了解决现有技术中存在索股架设过程中易受风力影响导致的索股架设效率低缺点。
