Arch rib lifting vertical rotation and cable-stayed vertical rotation combined construction method
The invention relates to an arch rib lifting vertical rotation and cable-stayed vertical rotation combined construction method which comprises the following steps: after horizontal splicing of arch ribs is completed at a low position, firstly, the arch ribs are lifted and vertically rotated to a certain height, a post-lifting shelving module is arranged on a lifting vertical rotation tower to temporarily shelve the arch ribs, first stress system conversion is completed, and then a buckling tower is erected; and anchor points on the arch ribs are connected through stay cables, so that secondary stress system conversion is completed, and finally the arch ribs are obliquely pulled and vertically rotated to the designed mounting height. The height of the arch rib assembling support, the height of the vertical lifting tower and the height of the cable-stayed vertical rotating buckling tower can be reduced at the same time, and the high-altitude construction risk and the material input cost are reduced to the maximum extent.
本发明涉及一种拱肋提升竖转和斜拉竖转组合施工方法，在低位完成拱肋卧拼后，首先将拱肋提升竖转到一定高度，并在提升竖转塔上设置提升后搁置模块临时搁置拱肋，完成第一次受力体系转换，然后搭设扣塔，并通过斜拉索连接拱肋上的锚点，完成第二次受力体系转换，最后将拱肋斜拉竖转到设计安装高度。本发明能够同时降低拱肋拼装支架、竖向提升塔架及斜拉竖转扣塔的高度，最大限度降低了高空施工风险以及材料投入成本。
