Gantry crane installation method for large-span public rail double-layer steel box girder
The invention relates to the technical field of public rail double-layer steel box girder hoisting, in particular to a gantry crane mounting method for a large-span public rail double-layer steel box girder, and aims at changing overwater operation into land operation and solving the problem of construction limitation of river-crossing high-pressure steel box girders. The gantry crane foundation extends to a road bridge, and the segment steel box girder is installed according to the characteristic that the height of the gantry crane is constant; a steel box girder jig frame system is arranged, a jig frame is arranged on a ground bridge, and a stress system is more stable; by optimizing the hoisting sequence of the sections of the steel box girder and reasonably arranging the closure sections, the mounting precision of the steel box girder and the line shape of the finished bridge are controlled.
本发明涉及公轨双层钢箱梁吊装技术领域，具体涉及一种大跨度公轨双层钢箱梁的龙门吊安装方法,将变水上作业为陆上作业，解决跨河涉高压钢箱梁施工局限问题；将龙门吊基础沿伸至路面桥上，利用龙门吊高度恒定的特点安装节段钢箱梁；布设钢箱梁胎架体系，将胎架设置到地面桥上，受力体系更稳定；通过优化钢箱梁节段吊装顺序，合理设置合拢段，控制钢箱梁安装精度及成桥线形。
