Mounting method for girder of suspension bridge
The invention provides a mounting method for a girder of a suspension bridge. The method comprises the following steps: firstly, installing an end girder section, mounting a beam moving rail at the bottom of the end girder section, then vertically hoisting an assembled beam section to the bottom of the installed girder section and to be connected with the beam moving rail arranged at the bottom ofthe installed girder section, longitudinally moving the beam section to the end of the installed girder section through the beam moving rail, then connecting the beam section with the installed girder section after being swung, moved and hoisted to the installation position, installing the beam moving rail at the bottom of the beam section to extend the beam moving rail, and repeating the above processes to install the next beam section until all the beam sections are installed. The hoisting beam sections are assembled on the ground, so the aerial work amount is small, and safety is high. Theground assembly efficiency is higher than the high-altitude suspension assembly efficiency, and the construction period is short. Compared with a cable crane scheme, the construction cost is low. Compared with a rail cable sliding method, the method of the invention has the following advantages: the use cost is low, the installation of the rail cable sliding equipment occupies a long main line construction period, the installation time of the cable-crossing crane is short, the main line construction period occupies less time, and the construction period advantage is obvious.
本发明提供了一种悬索桥主梁安装方法，首先安装端部主梁梁段，并在端部主梁梁段底部安装移梁轨道，然后将拼装好的梁段垂直起吊至已安装主梁梁段底部，并与已安装梁段底部的移梁轨道连接，之后通过移梁轨道将梁段纵移至已安装梁段端部，然后荡移吊装到安装位置后与已安装主梁梁段连接，并通过在该梁段底部安装移梁轨道以延长移梁轨道，重复以上过程进行下一梁段的安装至所有梁段安装完成。本发明吊装梁段拼装在地面进行，高空作业量少，安全性高。地面拼装比高空悬拼效率高，施工工期短。相对于缆索吊机方案，施工成本低。与轨索滑移方法相比使用成本低，轨索滑移设备的安装占用主线工期长，跨缆吊机安装时间短，主线工期占用少，工期优势明显。
