Buckle back cable whole bundle installation construction method in large-span arch bridge construction
The invention discloses a buckle back cable whole bundle installation construction method in large-span arch bridge construction. The buckle back cable whole bundle installation construction method comprises the following steps that S1, a portal and a construction platform are installed; s2, a back cable circulating lifting system and a buckle cable circulating lifting system are installed; s3, the whole bundle of back cables corresponding to the ith arch rib section are installed through the back cable circulating lifting system and the cable hoisting system; s4, the ith arch rib section is hoisted through a cable hoisting system, and the hoisting state is kept after hoisting is conducted in place; meanwhile, a buckle cable circulating traction system is installed, and a whole bundle of buckle cables corresponding to the ith arch rib section is installed through the buckle cable circulating lifting system and the buckle cable circulating traction system; s5, the hoisting state of the ith arch rib section is relieved, and meanwhile the back cable and the buckle cable corresponding to the ith arch rib section are tensioned; and S6, the steps S3 to S5 are repeated, and buckle cable and back cable installation of other arch rib sections is completed. According to the invention, collision and winding of the steel strands in the buckle back cable in the transportation and installation process are avoided, the construction risk is reduced, and the construction efficiency is improved at the same time.
本发明公开了一种大跨度拱桥施工中扣背索整束安装施工方法，包括以下步骤：S1、安装门架和施工平台；S2、安装背索循环提升系统和扣索循环提升系统；S3、利用背索循环提升系统和缆索吊装系统安装第i节拱肋节段对应的整束背索；S4、通过缆索吊装系统吊装第i节拱肋节段，吊装就位后保持吊装状态；同时安装扣索循环牵引系统，利用扣索循环提升系统和扣索循环牵引系统安装第i节拱肋节段对应的整束扣索；S5、解除第i节拱肋节段的吊装状态，同时张拉第i节拱肋节段对应的背索和扣索；S6、重复步骤S3至S5，完成其余拱肋节段的扣索和背索安装。本发明避免了运输及安装过程中扣背索中钢绞线发生碰撞、缠绕，降低了施工风险，同时提高施工效率。
