【摘要】：正11月9日14时,重达272 t的钢箱梁缓缓升起,在施工人员的操作下,稳稳地架设到虎门二桥大沙水道桥预定的位置上。虎门二桥首片钢箱梁架设成功,标志着世界最宽悬索桥进入钢箱梁"拼积木"阶段,上部结构施工将进入"快车道"。一辆甲板驳船载着钢箱梁从容驶至大沙水道桥位处,于46号、47号索夹处正下方精准定位。随后,在施工人员的操作下,全新研发的600 t全液压跨缆吊机下放钢绞线与吊具连接。吊装正式开始,跨缆吊
[Abstract]:At 14:00 on November 9, the steel box girder, weighing 272 tons, rose slowly and, under the operation of the constructors, was steadily set up to the predetermined position of the Dashaishui Bridge of the Humen No. 2 Bridge. The successful erection of the first steel box girder of the second Humen Bridge marks that the widest suspension bridge in the world has entered the "building block" stage of the steel box girder, and the superstructure construction will enter the "fast lane". A deck barge carries steel box girder to the bridge of Dashashui Road and is located exactly below the cable clamp No. 46 and 47. Then, under the operation of the constructor, the 600 t fully hydraulic cable crane is connected with the hoist. Hoisting begins formally, cross cable hoisting
