Large-span double-layer combined construction steel truss arch bridge and construction method thereof
The invention discloses a large-span double-layer combined construction steel truss arch bridge and a construction method thereof. The arch bridge comprises a plurality of steel truss temporary buttresses (12) and a plurality of arch rib temporary buttresses (13), the tops of the steel truss temporary buttresses (12) jointly support a lower chord in a steel truss structure, and the arch rib temporary buttresses (13) support arch ribs in the steel truss structure. The method comprises the steps of prefabricating all parts and then hoisting, installing and connecting on site. The steel truss arch bridge is integrally assembled on site, so that the steel truss arch bridge is convenient to assemble on site, short in construction period and high in installation precision, the influence of construction on the surrounding environment is reduced, the construction quality of the steel truss arch bridge is improved, the construction efficiency is improved, and the steel truss arch bridge has high popularization value.
本发明公开了一种大跨度双层合建钢桁架拱桥及其施工方法，拱桥包括多个钢桁架临时支墩（12）、多个拱肋临时支墩（13），由多个钢桁架临时支墩（12）顶部共同支撑钢桁架结构中的下弦杆，由拱肋临时支墩（13）支撑钢桁架结构中的拱肋。方法通过预制各个部件，然后现场吊装安装连接。本发明现场整体拼装，使钢桁架拱桥现场拼装便捷，施工周期短，安装精度高，减小了施工对周边环境的影响，提高了钢桁架拱桥施工质量，提高施工效率，有较高的推广价值。
