采用钢—混凝土结合底板的钢吊箱施工工艺

Workmanship Using Hanging Steel Box with Steel Concrete Composite Bottom Slab

上海长江大桥堡镇沙非通航孔承台施工采用钢-混凝土结合型底板、预应力悬吊牛腿的钢吊箱设计。施工过程充分利用潮位特征选择工艺,与传统工艺相比,取得了经济性和实用性具佳的效果,值得借鉴。

In construction of the bearing footing in the non-navigable channel at Baozhen Shoal in Shanghai Yangtze River Bridge Project, a steel hanging box is adopted, with a steel-concrete composite bottom plate and a suspended pre-stressed bracket. By making full use of the tide during construction, more economic and applicable benefits are obtained compared with the traditional art of works.
