Steel box girder unloading construction method
The invention belongs to the technical field of steel bridge construction, and particularly relates to a steel box girder unloading construction method which comprises the following steps that 1, an unloading device is preassembled on a segment assembling bridge girder erection machine, and the segment assembling bridge girder erection machine moves to a bridge rectifier; 2, the unloading device is installed on the segment assembling bridge girder erection machine; 3, hoisting the segmental steel box girder; 4, butting the upper suspender and the lower suspender, and suspending the segmental steel box girder; 5, assembling and welding the fixed section steel box girder to form a whole-span steel box girder, and unloading the whole-span steel box girder; and 6, separating the bottom surfaceof the whole-span steel box girder from the balance beam. The method has the beneficial effects that the sinking speed can be effectively controlled, so that the unloading process is stable, balanced, synchronous, unified and orderly, and the construction quality and the personnel safety can be reliably guaranteed.
本发明属于钢桥梁施工技术领域，具体而言，涉及一种钢箱梁卸载施工方法，包括如下步骤：步骤1，预装卸载装置在节段拼装架桥机上，节段拼装架桥机移动至桥堆；步骤2，节段拼装架桥机上安装卸载装置；步骤3，吊装节段钢箱梁；步骤4，对接上吊杆与下吊杆，悬挂节段钢箱梁；步骤5，拼装并焊接固定节段钢箱梁，形成整跨钢箱梁并进行卸载；步骤6，整跨钢箱梁底面与平衡梁分离。本发明提供的有益效果为能有效控制下沉速度、使卸载过程平稳均衡、同步统一、有序进行，施工质量和人员安全均能得到可靠保证。
