Double-steel box girder alternate pushing anti-deviation construction method
The invention belongs to the technical field of steel structure bridge incremental launching construction, and particularly relates to a double-steel box girder alternate incremental launching anti-deviation construction method. The method comprises the steps that a pushing assembly is installed; assembling a guide beam; the bridge deck system of the first section of the left part and the bridge deck system of the first section of the right part are spliced; pushing the two spliced bridge deck systems with the guide beams to the opposite bank by an inter-node distance; the two bridge deck systems are sequentially and alternately pushed to the opposite bank, and steel box girders are synchronously erected between sections till the two bridge deck systems are pushed in place; the bridge deck system falls to the designed elevation through the pushing assembly; pushing construction of the bridge deck system is completed; and sequentially erecting side span bridge deck systems on the two banks, welding and coating beam bottoms of the side span bridge deck systems on the two banks and the bridge deck system pushed in place, and erecting and welding a middle cross beam between the two bridge deck systems. While the pushing construction difficulty of the asymmetric steel box girder is reduced, the construction safety and efficient constructability of the asymmetric steel box girder can be guaranteed, and the method has the advantages of being reasonable in stress, safe and reliable.
本发明属于钢结构桥梁顶推施工技术领域，具体涉及一种双钢箱梁交替顶推防偏移施工方法。本发明包括安装顶推组件；拼装导梁；拼装左幅第一节间的桥面系和右幅第一节间的桥面系；将两幅已拼装的带有导梁的桥面系向对岸顶推一个节间距离；两幅桥面系依次交替向对岸顶推，并同步逐节间架设钢箱梁，直至两幅桥面系顶推到位；利用顶推组件将桥面系落梁至设计标高；完成桥面系顶推施工；依次架设两岸边跨桥面系，对两岸边跨桥面系和上述顶推到位的桥面系进行粱底焊接和涂装，再在两幅桥面系之间架设并焊接中横梁。本发明在降低非对称钢箱梁顶推施工难度的同时，亦能保证该非对称钢箱梁施工的安全性和高效施工性，具备了受力合理及安全可靠的优点。
