Large-span arch bridge side wave wind cable adjusting method, system, equipment and medium
The invention relates to the technical field of large-span arch bridges, in particular to a large-span arch bridge side wave wind cable adjusting method, system and device and a medium. The method comprises the following steps that a cable force adjusting mechanism is arranged on each side wave wind cable base; after the arch rib cantilever sections are hoisted in place, the arch rib cantilever sections are connected with the corresponding side wave wind cables; the cable force adjusting mechanism pre-tightens the side wave wind cable, so that after the cable force of the side wave wind cable reaches a first threshold value, the hoisting point loosens the arch rib cantilever section; the axis and the elevation of the arch rib cantilever section are collected in real time and fed back to the cable force adjusting mechanism according to the difference value between the axis and the elevation and the design value, and the cable force is adjusted till the axis and the elevation of the arch rib cantilever section reach the design value. According to the method, on one hand, a manual chain block is not needed to adjust the cable force back and forth, on the other hand, the hoisting time of the crane on the arch rib cantilever section can be greatly shortened, the construction efficiency is improved, and the requirements for the construction environment and the wind power during construction are greatly reduced.
本发明涉及大跨径拱桥技术领域，尤其涉及一种大跨径拱桥侧浪风索调节方法、系统、设备及介质，包括如下步骤：在每个侧浪风索底座上设置索力调节机构；将拱肋悬臂节段吊装到位后，与对应的侧浪风索进行连接；索力调节机构对侧浪风索进行预紧，使侧浪风索的索力达到第一阈值后，起吊点松开该拱肋悬臂节段；实时采集该拱肋悬臂节段的轴线与标高，根据其与设计值的差值，反馈至索力调节机构，对索力进行调整，直至该拱肋悬臂节段的轴线与标高达到设计值。本发明中，一方面无需人工手拉葫芦进行来回的索力调整，另一方面可以大幅减少起重机对拱肋悬臂节段的吊装时间，提高施工效率，对施工环境和施工时风力要求大幅降低。
