Construction method of steel truss girder arch bridge
The invention relates to a construction method of a steel truss girder arch bridge. The construction method comprises the following steps: erecting a main girder; erecting an assembling bracket and a lifting bracket on the main beam; arch springing sections and a central section are formed on the assembling support in an assembling mode; the central segment is lifted to the designed height through the lifting support; and closing the arch foot sections and the central section to form the bridge arch rib. A high lifting support or an assembling support does not need to be built, the support building cost is reduced, meanwhile, channel passing or high-altitude assembling cannot be affected, the application range is wider, and safety is higher.
本发明涉及提供了一种钢桁梁拱桥的施工方法，其包括以下步骤：架设主梁；在所述主梁上架设拼装支架以及提升支架；在所述拼装支架上拼装形成拱脚节段以及中央节段；通过所述提升支架将所述中央节段提升至设计高度；将所述拱脚节段与所述中央节段合龙形成桥梁拱肋。既不需要搭建很高的提升支架或拼装支架，降低了搭建支架的成本，同时不会影响航道通行或高空拼装，适用范围更广，安全性更高。
