Large-span curve steel box girder mounting system and construction method
The invention relates to a large-span curve steel box girder installation system and a construction method. The large-span curve steel box girder installation system comprises a steel pipe support, a steel pipe pile variable-diameter connecting structure, a straining beam cantilever hoisting device, an arch rib installation support, an arch rib temporary locking frame and a warning navigation anti-collision pile. Comprising the steps of steel box girder support erecting, steel box girder hoisting, arch rib support erecting, arch rib assembling and anti-collision pile driving. The construction platform has the advantages that the steel pipe supports support the steel box girders, the cross tie beams are adopted between the steel box girders to form the construction platform system, and the problems that large-span curve steel box girders are large in assembly difficulty and insufficient in construction space are solved; a steel pipe pile variable-diameter connecting structure solves the problems that the clearance below a steel box girder is too large, and the rigidity of a single-diameter steel pipe pile erecting support is insufficient. The collar beam cantilever hoisting technology solves the problem that the offset amplitude is too large and is not easy to control in the collar beam hoisting process; and the arch rib mounting bracket is also arranged, so that the problem of difficulty in the curved arch rib splicing process is solved.
本发明涉及一种大跨径曲线钢箱梁安装体系及施工方法，包括钢管支架、钢管桩柱变径连接结构、系梁悬臂吊装装置、拱肋安装支架、拱肋临时锁定架和警示导航防撞桩；包括步骤：钢箱梁支架搭设、钢箱梁吊装、拱肋支架搭设、拱肋拼装、防撞桩打设。本发明的有益效果是：钢管支架支撑钢箱梁，钢箱梁之间采用横系梁形成施工平台体系，解决了大跨径曲线钢箱梁拼装难度大，施工空间不足的问题；钢管桩柱变径连接结构，解决了钢箱梁下净空过大，单一直径钢管桩搭设支架刚度不足的问题；系梁悬臂吊装技术，解决了系梁吊装过程中偏移幅度过大不易控制的问题；还设有拱肋安装支架，解决了曲线拱肋拼装过程中困难的问题。
