Method for vertically rotating main tower of single-tower double-layer steel truss girder cable-stayed bridge
The invention relates to the technical field of cable-stayed bridge main tower vertical rotation, and discloses a single-tower double-layer steel truss girder cable-stayed bridge main tower vertical rotation method which is characterized by comprising the following steps that S1, a temporary assembly platform is erected on a bridge floor, the main tower structure and the bridge floor are assembled at an angle of 5 degrees, and overall assembly is completed on the bridge floor; s2, the auxiliary tower is assembled, cages, pressing rods, flexible pull rods, inhaul cable anchor points, back cable anchor points, steel strand jacks and the like are installed on the two sides, an auxiliary tower portal frame is installed on the main tower, front anchor pulling points are arranged on the main tower, rear anchor pulling points are arranged on the bridge floor, the main tower is assembled on the bridge floor, the construction condition is good, the welding quality is easier to control, the main tower installation time is greatly shortened, and the construction efficiency is improved. The investment of temporary equipment is saved, the construction machinery cost is greatly reduced, the structural safety is easier to guarantee, and meanwhile, the main tower structure is assembled to form an angle of 5 degrees with the bridge floor, so that the pulling is easier than the direct horizontal direction.
本发明涉及斜拉桥主塔竖转技术领域，且公开了一种独塔双层钢桁梁斜拉桥主塔竖转方法，其特征在于，包括以下步骤：S1、在桥面上搭设临时拼装平台，主塔结构拼装同桥面呈5°，在桥面上完成整体拼装；S2、拼装副塔，安装两侧吊笼、压杆、柔性拉杆、拉索锚点、背索锚点、钢绞线千斤顶等，将副塔门架安装于主塔上，主塔上设置前拉锚点，桥面上设置后拉锚点，设置主塔在桥面拼装，施工条件较好，焊接质量更易控制，大幅缩短主塔安装时间，节省了临时设备投入，施工机械成本大大降低，结构安全更易保障，同时主塔结构拼装同桥面呈5°，这样比直接水平方向更容易拉动。
