| Abstract: | 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. |
