全封闭挂篮在铁路跨越高速公路施工中的应用

The Application of Full-Closed Hanging Basket in Railway Construction Crossing Expressway

悬臂法施工是大跨径连续梁施工的常用方法,更加适用于跨越公路、铁路、河道的桥梁工程,而且受地形影响小,施工不影响交通或通航。论文结合宁启铁路通启高速特大桥48m+80m+48m跨沪陕高速路连续梁全封闭挂篮施工技术,阐述了全封闭挂篮的设计要点及施工过程中的安全控制措施。

Cantilever constructionis a common method forlarge-span continuous beam construction.It is more suitable for bridge engineering crossing highways,railways,rivers,etc.,and is less affected by terrain,the construction does not affect traffic.Based on the combines the construction technology of the full-closed hanging basket of the continuous beam of the Nanjing-Nantong Railway Tongqi expressway super bridge acrossthe Hushan expressway,this paper expoundsthe design points andthe safetycontrol measures during construction.
