龙抬头隧洞衬砌施工中,受龙抬头改造工程的实际地形及结构形式影响,流线型洞身衬砌是整个工程的重点。传统施工方法中,异型洞身衬砌多采用满堂脚手架拼装普通钢模板进行施工,此类方法多施工工期较长,成本大。实践证明,采用组合式顶拱钢模台车,可有效控制龙抬头衬砌建设工期,降低运行成本,且施工质量易于保证。
Long rise tunnel lining construction, by the dragon head elevation transformation of the actual topography and structure of the form of impact, streamlined tunnel lining is the focus of the entire project. In the traditional construction methods, the special-shaped tunnel lining is usually constructed by using full scaffolding to assemble common steel formwork. Such methods have a long construction period and a large cost. Practice has proved that the use of modular roof arch steel mold trolley, can effectively control the construction period of the dragon head lining, reduce operating costs, and the construction quality is easy to guarantee.
