黄河流凌河段深水栈桥施工技术

乌锡铁路黄河特大桥桥址位于三湖河口至昭君坟段,北岸为乌拉山山前倾平原,南岸为鄂尔多斯台地,桥址主河道宽710 m,水深3~20 m左右,处于严重的流凌河段,搭建施工栈桥成功与否是确保黄河特大桥顺利施工的关键所在。通过方案比选,确定采用浮桥方式,解决了流凌段栈桥的快速搭拆施工难题,取得了一定的经验。

Deepwater Pier Construction Technology on Ice Flowing Section of Huanghe River

Yellow River extra-large bridge on Wutin railway is located in the section between the lakes of the Yellow River estuary to Zhaojunfeng, with Ural mountain foot plain on the north and Erdos plateau on the south. It is a typical ice flowing section with a river width of 710 m and water depth of 3 -20 m. Thus, the floating bridge building is the key for the con- struction of Huanghe river bridge. Through scheme selection, the float bridge is chosen which solves the difficulty of rapid installation and demolition of floating bridge in ice floating section.
