钢吊箱围堰在三门江大桥施工中的应用

Application of Steel Hoisting Box Cofferdam in Sanmenjiang Bridge Construction

摘要:

三门江大桥水中主墩系高桩承台，采用钢吊箱围堰法施工，利用简易的型钢拉压柱作为吊箱的吊挂结构，将吊箱吊挂在钻孔桩钢护筒上，施工操作简便，降低工程成本，是一项值得推广和应用的施工技术。

Abstract:

The in-water main piers of Sanmenjiang Bridge are elevated pile caps that were constructed by steel hoisting box cofferdams. Simple steel reinforced pile with tensile and compressive strength was taken as hanging parts of hoisting box. It is easy to operate and can lower the construction cost, so this technology deserves to be popularized.
