摘要
随着桥梁工程中连续箱梁的应用逐步向大跨度方向发展 ,京福高速公路跨京杭运河特大桥预应力混凝土连续箱梁 ,采用了菱形桁架式悬臂挂篮浇筑 .介绍了挂篮的构造及各部件的作用、挂篮的顶压试验。
There is an increasing tendency to extend the span of the continuous box girder in bridgework.The cast-in-place cantilever method with rhombic trussed cradle is adopted at the giant prestressed concrete continuous box girder bridge across the Beijing-Hangzhou Grand Canal,in the Beijing-Fuzhou Expressway.Demonstrated here are the structure of the cradle and the functions of the various parts,the top pressure test,and the pouring technique of the steel concrete box girder.
