Steel arch bridge arch rib horizontal floating transportation overwater vertical rotation installation method
The invention relates to a steel arch bridge arch rib horizontal type floating transportation overwater vertical rotation installation method which comprises the steps that firstly, arch rib vertical rotation buckling towers are erected on the two banks respectively, arch foot pre-buried sections are constructed, meanwhile, two vertical rotation sections of an arch rib are assembled on a backfield, the arch rib vertical rotation sections are transported to a bridge site through ships in a floating mode respectively, the arch foot ends of the two arch rib vertical rotation sections are hinged to the arch foot pre-buried sections on the two banks respectively, and then the arch rib vertical rotation buckling towers and the arch foot pre-buried sections on the two banks are installed. Inhaul cables are connected between the buckling towers on the two banks and the two arch rib vertical rotating sections respectively, and the two arch rib sections are vertically rotated to the designed installation height through a conventional vertical rotating method; and finally, the arch rib closure section is transported to the position below the bridge in a floating mode, the closure section is lifted and installed through the lifting scaffolds on the two arch rib vertical rotation sections, and arch rib vertical rotation installation construction is completed. According to the method, the problems that in-situ horizontal splicing and vertical rotation cannot be conducted on the wading arch bridge arch rib, and the overall floating transportation risk of a conventional arch rib is high are solved, the application range of arch rib vertical rotation construction is expanded, and compared with a conventional vertical rotation method, the construction efficiency can be further improved.
本发明涉及一种钢拱桥拱肋卧式浮运水上竖转安装方法，先在两岸分别搭设拱肋竖转扣塔，施工拱脚预埋段，同时在后场拼装拱肋的两个竖转节段，分别用船浮运至桥位，将两个拱肋竖转节段的拱脚端分别与两岸拱脚预埋段铰接，在两岸扣塔和两拱肋竖转节段间分别连接拉索，采用常规竖转法将两拱肋节段竖转到设计安装高度；最后将拱肋合龙段浮运至桥下，通过两拱肋竖转段上的提升鹰架提升安装合龙段，完成拱肋竖转安装施工。本发明解决了涉水拱桥拱肋不能进行原位卧拼竖转，以及常规拱肋整体浮运风险高的问题，拓展了拱肋竖转施工的适用范围，而且与常规竖转法相比可进一步提高施工效率。
