Inland waterway steel box basket arch large segment segmented hoisting method
The invention provides an inland waterway steel box basket arch large-segment segmented hoisting method, which belongs to the field of bridge construction, and specifically comprises the following steps: 1) dividing bridge structure segment blocks, and transporting the blocks to a construction site; (2) a foundation of a construction site is treated, a riverway side assembling area site is leveled, and a temporary support is built; (3) the arch foot sections, the main straining beams, the cross beams and the arch rib large sections are sequentially hoisted, and fixing work among the blocks is synchronously carried out; 4) constructing a bridge deck system and an accessory structure; according to the method, the construction efficiency can be improved, the construction period can be shortened, and the method is suitable for the special conditions that long-time navigation closing construction cannot be conducted on the inland waterway and the like, and the current waterway does not have large floating crane integral hoisting operation.
本发明提供一种内河航道钢箱提篮拱大节段分段吊装方法，属于桥梁施工领域，具体包括如下步骤：1)：将桥梁结构节段块体划分，并将各块体运送至施工现场；2)：处理施工现场的地基，平整河道边拼装区场地并搭建临时支架；3)：依次对拱脚节段及主系梁、横梁和拱肋大节段进行吊装，并同步进行各块体之间的固定工作；4)：施工桥面系及附属结构；5)：拆除所有临时支架，完成内河航道钢箱提篮拱大节段分段吊装，本发明可以提高施工效率缩短工期，适用于内河航道等不能长时间封航施工以及现状航道不具备大型浮吊整体吊装作业的特殊情况。
