Dismantling and building integrated construction method for dismantling old rigid frame bridge in-situ newly-built suspension bridge
The invention relates to a dismantling and building integrated construction method for dismantling an old rigid frame bridge in-situ newly-built suspension bridge, which comprises the following steps of: firstly dismantling an old bridge, constructing an anchorage, a main tower and a side span of the newly-built suspension bridge, installing a suspension bridge main cable and a cable loading crane, dismantling a mid-span closure section, the side span and a mid-span main beam cantilever of the old bridge by using the cable loading crane, and hoisting a newly-built suspension bridge steel box beam. And meanwhile, a side span closure section, a side span cast-in-place section and a side pier of the old bridge are sequentially dismantled through a crawler crane. The bridge dismantling process and the bridge building process are in cross operation and synchronous construction, and the construction period can be shortened; an old bridge deck is used as a new suspension bridge pilot cable river-crossing traction platform, navigation is not affected, and cost is saved; the cable crane for newly building the suspension bridge is used for dismantling the old bridge, and the construction efficiency and safety are high.
本发明涉及一种拆除老旧刚构桥原位新建悬索桥的拆建一体化施工方法，先拆除旧桥，施工新建悬索桥的锚碇、主塔及边跨，安装悬索桥主缆及缆载吊机，利用缆载吊机拆除旧桥中跨合拢段及边跨和中跨主梁悬臂、吊装新建悬索桥钢箱梁，同时利用履带吊依次拆除旧桥的边跨合拢段、边跨现浇段及边墩。本发明拆桥与建桥过程交叉作业、同步施工，有利于缩短工期；利用旧桥桥面作为新建悬索桥先导索过江牵引平台，不影响通航且节约了成本；利用新建悬索桥施工的缆载吊机拆除旧桥，施工效率及安全性高。
