Method for synchronously installing double arch ribs of half-through steel box basket arch bridge
The invention relates to a method for synchronously installing double arch ribs of a half-through steel box basket arch bridge. The method comprises the following steps of: connecting sections of the double arch ribs through a chain block, keeping a small distance, simultaneously hoisting the double arch ribs through cable cranes on two sides, and enabling the double arch ribs to pass through a buckle cable of two installed arch ribs in an air moving process, avoiding the conflict with a preorder buckle cable; and after the arch rib sections are hoisted in place, gradually loosening the chain block, gradually increasing the distance between the two arch rib sections, synchronously moving the arch rib sections to the to-be-installed position to be in butt joint with the installed arch ribs, and therefore accurate positioning and synchronous installation of the arch rib sections are achieved.
本发明涉及一种中承式钢箱提篮拱桥双幅拱肋同步安装方法，将双幅拱肋节段通过手拉葫芦连接并保持一较小间距，两侧缆索吊将双幅拱肋同时起吊，空中移动过程中可从已安装完成的两幅拱肋的扣索之间通过，从而避免与前序扣索发生冲突；拱肋节段起吊到位后，逐渐放松手拉葫芦，使两拱肋节段的间距逐渐增大，同步移动到待安装位置与已安装拱肋对接，从而实现拱肋节段准确定位和同步安装。
