Main bridge steel structure construction method
The invention discloses a main bridge steel structure construction method, and relates to the technical field of bridge construction. The method comprises the following specific steps. Regional division-mounting of baffles and pier columns-mounting of steel pipe piles and platform supporting columns-mounting of inter-column supports and sliding beams to form sliding rails-repeated construction of south banks-completion of platform supports covering rivers-mounting of lower chords and lower-layer bridge floors-mounting of upper chords and upper-layer bridge floors-mounting of upper-layer cantilevers and lower-layer cantilevers-splicing of sliding sheets repeatedly assembling the sliding units until the sliding units are closed; hoisting the last sliding unit; and completing the installation of the main bridge steel structure. By adopting the construction method, the operation risk can be reduced, the construction period is shortened, materials are saved and the cost is reduced.
本发明公开了一种主桥钢结构施工方法，涉及桥梁施工技术领域。具体步骤包括：划分区域→安装挡板和墩柱→安装钢管桩和平台支撑柱→安装柱间支撑和滑移梁形成滑移轨道→南岸重复施工→完成覆盖河流的平台支撑→安装下弦杆和下层桥面→安装上弦杆和上层桥面→安装上层悬挑和下层悬挑→拼装滑移单元→重复拼装滑移单元至合拢→吊装最后一个滑移单元→完成主桥钢结构的安装。采用本施工方法能够实现降低操作风险、缩短工期、节省材料和降低成本。
