Method for installing steel box girder of large-span highway-rail dual-purpose three-tower double-cable-plane cable-stayed bridge
The invention discloses a method for installing a steel box girder of a large-span highway-rail dual-purpose three-tower double-cable-plane cable-stayed bridge. The method comprises the following steps: (1) erecting a steel-concrete combined section triangular bracket bracket; (2) mounting a steel-concrete combined section of the MP4 tower; (3) mounting steel-concrete combined sections of the MP3 tower and the MP5 tower; (4) mounting a G2 section steel box girder of the MP4 tower, carrying out load test on a deck crane and mounting and debugging a temporary tool trolley; the invention discloses a method for installing a steel box girder of a large-span highway-rail dual-purpose three-tower double-cable-plane cable-stayed bridge, which comprises the following steps of (1) construction of a steel box girder, (2) construction of a steel box girder, (3) construction of a temporary cable, (6) installation of a standard section steel box girder of an MP4 tower, (7) welding of a circular seam of the steel box girder, (8) high-bolt construction of the circular seam of the steel box girder, (9) installation of a permanent cable and (10) installation of a closure section steel box girder.The method is simple, improves the installation precision of the steel box girder and reduces the construction difficulty.
一种大跨度公轨双用三塔双索面斜拉桥钢箱梁安装的方法，包括以下步骤：1）钢混结合段三角牛腿支架搭设；2）MP4塔钢混结合段安装；3）MP3塔和MP5塔钢混结合段安装；4）MP4塔G2节段钢箱梁安装、桥面吊机荷载试验及临时工装小车安装调试；5）临时索施工；6）MP4塔标准节段钢箱梁安装；7）钢箱梁环缝焊接；8）钢箱梁环缝高栓施工；9）永久索安装；10）合拢段钢箱梁安装。本发明提供了一种简单、提高钢箱梁安装精度、降低施工难度的大跨度公轨双用三塔双索面斜拉桥钢箱梁安装的方法。
