Tower-passing construction method for main tower internally-penetrating type steel box girder cable bearing bridge
The invention relates to a tower-passing construction method for a main tower internally-penetrating type steel box girder cable bearing bridge. The tower-passing construction method comprises the steps that a to-be-installed steel box girder is divided into side steel box girder sections, a middle steel box girder section and a steel cross beam section; the side steel box girder sections and the middle steel box girder sections are sequentially hoisted to the slide way girder on the main span side; the side steel box girder sections and the middle steel box girder sections are longitudinally pushed to the designed positions towards the side span sides correspondingly, and are spliced from front to back to form side steel box girders and middle steel box girders; and the multiple steel cross beam sections are hoisted to the positions between the corresponding side steel box girders and the corresponding middle steel box girders, butt joint is completed, and the whole side span steel box girder is formed. The tower-crossing construction method can adapt to cable bearing bridge construction with the side span not meeting the overwater hoisting condition, the range of a side span construction support does not need to be widened, a transverse moving system and a synchronous pushing control system do not need to be arranged either, the construction system and installation platform design can be simplified, and the construction efficiency is improved. The support and foundation treatment work amount can be effectively saved, and the single-time main beam section hoisting weight is reduced.
本申请涉及一种主塔内穿式钢箱梁缆索承重桥梁过塔施工方法，包括：将待安装的钢箱梁分为边钢箱梁节段、中钢箱梁节段、钢横梁节段；在主跨侧将边钢箱梁节段和中钢箱梁节段依次吊装至滑道梁上；分别将边钢箱梁节段和中钢箱梁节段向边跨侧纵向顶推至设计位置，从前至后拼接组成边钢箱梁和中钢箱梁；将多个钢横梁节段吊装至对应的边钢箱梁和中钢箱梁之间，并完成对接，形成整幅边跨钢箱梁。本申请提供的过塔施工方法能够适应边跨不具备水上吊装条件的缆索承重桥梁施工，不需要对边跨施工支架范围进行加宽，也不需要设置横移系统、同步顶推控制系统，有利于简化施工系统及安装平台设计，能够有效节省支架和地基处理工程量，减小单次主梁节段吊装重量。
