Steel truss girder cable-stayed bridge vertical rotation construction method
The invention relates to a vertical rotation construction method for a steel truss girder cable-stayed bridge. The method comprises the specific steps that S1, auxiliary measures are adopted for construction, wherein auxiliary measures comprise a steel girder splicing platform, a temporary hinge, a buckling and hanging system, a tower top crane and a horizontal jack assembly; s2, symmetrically and vertically assembling partial segments of the main beam; s3, symmetrically and vertically rotating partial sections of the main beam; s4, mounting the rest sections of the main beam; s5, stay cables are installed; and S6, removing auxiliary construction measures. The tower top crane and the buckling and hanging system are used for achieving vertical assembling and symmetrical rotating construction of the main beams of the steel truss girder cable-stayed bridge, the assembling speed of the steel beams is high, the linear control precision is high, large overwater hoisting machinery is not needed, temporary supports are arranged in water, the number of temporary facilities is small, economical efficiency is good, and a navigation channel is not occupied; the device is wide in application range, is suitable for crossing complex obstacles such as high-speed rails and highways or water bridge construction, and is suitable for single-tower, multi-tower and cable-stayed bridges.
本发明是一种钢桁梁斜拉桥竖向转体施工方法，具体步骤为：S1、辅助措施施工：辅助措施包括：钢梁拼装平台、临时铰、扣挂系统、塔顶吊机和水平千斤顶组件；S2、主梁部分节段对称竖向拼装；S3、主梁部分节段对称竖向转动；S4、主梁剩余节段安装；S5、安装斜拉索；S6、拆除辅助施工措施。本发明利用塔顶吊机和扣挂系统实现钢桁梁斜拉桥主梁竖向拼装，对称转体施工，钢梁拼装速度快，线性控制精度高，无需大型水上吊装机械，水中设置临时支撑，临时设施少，经济性好，不占用航道；使用范围广，适用于跨越高铁、公路等复杂障碍的情况或水上桥梁施工，且对于单塔、多塔、斜拉桥均适用。
