Installation method of large-span light curve truss girder bridge in mountainous area
The invention relates to the field of bridge engineering, in particular to a mountainous area large-span light curve truss girder bridge installation method which comprises a track foundation, a track beam, an assembly support, a portal crane, a pushing slide way, a walking type pushing device, a light truss girder, a front guide beam, a steel tube tower, a cable-stayed steel cable, a back cable, a pier, a bracket, a bracket inhaul cable and a pushing fitting curve. Comprising the following steps of (1) site and support arrangement, (2) portal crane installation, (3) slideway and walking type thruster installation, (4) light truss girder and front guide girder assembly, (5) steel tube tower and stay cable installation and (6) differential thrusting construction, and compared with an existing bridge installation method, the construction site is saved, the production efficiency is improved, and meanwhile the construction cost is reduced.
本发明涉及桥梁工程领域，尤其涉及一种山区大跨度轻型曲线桁架梁桥安装方法，包含轨道基础、轨道梁、拼装支架、门式起重机、顶推滑道、步履式顶推器、轻型桁架梁、前导梁、钢管塔架、斜拉钢索、背索、桥墩、托架、托架拉索、顶推拟合曲线，包括以下步骤：1）场地及支架布置；2）门式起重机安装；3）滑道及步履式顶推器安装；4）轻型桁架梁及前导梁拼装；5）钢管塔架及斜拉索安装；6）差异化顶推施工；其相较于现有桥梁安装方法节约了施工场地，提高了生产效率，同时降低了施工成本。
