Main bridge main span steel structure segment construction method based on cantilever aerial work platform
The invention discloses a main bridge main span steel structure section construction method based on a cantilever aerial work platform, which is used for constructing a next main bridge steel structure section at the end part of a constructed main bridge steel structure, and the main bridge steel structure section comprises a plurality of components, all components corresponding to a main bridge section cantilever panel, a main bridge section upper-layer bridge panel, a main bridge section upper chord, a main bridge section lower-layer bridge deck system, a main bridge section lower chord, a main bridge section adjusting web member and a main bridge steel structure section are sequentially welded in a suspension operation platform of the aerial operation platform to achieve splicing. Therefore, all the spare parts forming the main bridge steel structure sections can be transported and hoisted to the aerial operation platform one by one in sequence to be in butt joint and welded and assembled, and therefore construction of the all-welded steel truss bridge is completed.
本发明公开了一种基于悬臂空中作业平台的主桥主跨钢结构节段施工方法，用于在已施工完成的主桥钢结构端部施工下一节主桥钢结构节段，所述的主桥钢结构节段包括有多个构件，对应为主桥节段悬挑面板、主桥节段上层桥面板、主桥节段上弦杆、主桥节段下层桥面系、主桥节段下弦杆以及主桥节段调整腹杆，主桥钢结构节段的各个构件在空中作业平台的悬挂操作平台中依次焊接实现拼接。由此可见，本发明可以将构成主桥钢结构节段的各散件按序逐一通过运输、起吊至空中作业平台中进行对接、焊接拼装，从而完成全焊钢桁梁桥的施工。
