Multi-station mounting method for girder of steel truss girder suspension bridge
The invention discloses a multi-station mounting method for a girder of a steel truss girder suspension bridge girder. The method comprises the steps that a plurality of girder section hoisting stations are symmetrically arranged in the midspan and on the two sides of the midspan of each main span, and girder sections are symmetrically pushed and erected in the direction of a bridge tower until closure is achieved to complete girder erection work; and a hoisting station is also arranged on a side span, and in the erecting process of the main span beam section, lifting erecting of the side span beam section is inserted. According to the method, the main beam hoisting stations are arranged on the main span, the steel truss girder hoisting construction period is remarkably shortened, and the steel truss girder erecting efficiency is greatly improved.
本发明公开了一种钢桁梁悬索桥主梁多工位安装方法，包括在每个主跨的跨中及跨中两侧对称设置多个主梁梁段吊装工位，并向桥塔方向对称推进架设梁段，直至合龙，完成主梁架设工作，还包括在边跨也设置一个吊装工位，在主跨梁段架设过程中穿插边跨梁段的吊装架设。本发明的方法在主跨设置多个主梁吊装工位，钢桁梁吊装工期显著减少，大大提高钢桁梁架设效率。
