河南省板桥水库复建工程坝顶门机桥的设计,大胆采用了焊接骨架式钢筋砼异型梁组合结构,得到了良好的使用和经济效益,同时结合施工栈桥,又解决了施工机械不足,工期紧,施工场地窄小等一系列问题,据我们了解,目前国内大型坝顶门机桥采用这种结构尚属首次,因此具有特殊的意义。 The design of the bridge deck bridge at Banqiao Reservoir Reconstruction Project in Henan Province boldly adopts the combination structure of welded skeleton reinforced concrete profiled beam and has obtained good use and economic benefits. At the same time, with the construction of trestle bridge, it also solves the problems of lack of construction machinery, Tight, narrow construction site and a series of problems, we understand that the current domestic large-scale dam top door bridge is the first time using this structure, it is of special significance.
