Construction method for hoisting large-span steel bridge box girder and hoisting and installing special-shaped component
The invention provides a construction method for hoisting a large-span steel bridge box girder and hoisting and installing a special-shaped component. The method comprises the steps of construction preparation, segment division design, hoisting and welding scheme analysis, crane type selection, foundation treatment, support system erection, special scheme evaluation, hoisting implementation, technical improvement, steel arch hoisting analysis, same-direction double-hoisting scheme innovation, hoisting completion and welding implementation, and hoisting is conducted on a large-span steel bridge box girder and a special-shaped component. According to the method, the hoisting scheme is optimized, the section size, the weight and the hoisting position are converted into a function relation, hoisting equipment is reasonably configured and corresponds to a construction road and a hoisting foundation respectively, the construction difficulty is reduced, and the positioning precision is improved. And finally, the engineering quality is improved.
本发明提供了大跨度钢桥箱梁吊装及异型构件吊装安装施工方法，包括以下步骤，施工准备→节段划分设计→吊装焊接方案分析→吊车选型→基础处理→支撑体系架设→专项方案评审→吊装实施→技术改进→钢拱吊装分析→创新同向双吊方案→吊装完成→焊接实施，对大跨度钢桥箱梁吊装及异型构件进行吊装；本发明所述通过优化吊装方案，将节段尺寸、重量与吊装位置换算成函数关系，合理配置起吊设备并分别对应施工道路及吊装基础，降低施工难度，提高定位精度。最终实现工程质量的提升。
