Arch rib side section cable-stayed buckling and hanging and middle section and large section lifting installation method
The invention relates to an arch rib side section cable-stayed buckling and mounting method and a middle section large section lifting and mounting method. An arch rib is divided into two side sections and a middle section; symmetrically hoisting the arch ribs on the two side sections by using a cable crane section by section; after the arch ribs on the two side sections are installed, on-arch cranes are installed on the arch ribs on the two side sections respectively; transporting the middle-section arch rib to the position below the bridge site, lowering the lifting appliance by the arch crane, and vertically lifting the middle-section arch rib to be hinged and closed with the two side-section arch ribs. According to the method, a cable hoisting-cable-stayed buckling hanging method is combined with an arch crane, so that the height of a cable crane main tower can be reduced, and the construction cost and the safety risk are reduced; splicing of the middle section arch ribs and hoisting of the side sections can be conducted at the same time, and compared with a traditional construction method, the construction period can be greatly shortened.
本发明涉及一种拱肋边段斜拉扣挂及中段大节段提升安装方法，将拱肋划分为两个边段和一个中段；采用缆索吊分节段对称吊装两边段拱肋；两边段拱肋安装完成后，在两边段拱肋上分别安装拱上吊机；将中段拱肋运至桥位下方，拱上吊机下放吊具，垂直起吊中段拱肋与两边段拱肋铰接合龙。本发明将缆索吊装‑斜拉扣挂法与拱上吊机相结合，可降低缆索吊主塔的高度，从而降低施工成本及安全风险；中段拱肋的拼装可与边段吊装同时进行，相比传统施工方法能大幅缩短工期。
