水利水电工程全圆断面隧道衬砌模板比选

Selection of Lining Formworks for Full-circular Cross-section Tunnels of Water Conservancy and Hydropower Projects

通过南水北调05,06标段施工中使用的针梁式模板台车、组合模板和简易模板台车的施工工艺和施工成本的分析比较,说明在水利水电工程全圆衬砌施工过程中,通过比选确定衬砌模板形式,对项目成本控制以及提高衬砌施工进度起着关键性作用。

Needle-type formwork jumbos, composite formworks and simple formwork jumbos are used in the construction of No. 05 and No. 06 bid sections of South-to-North Water Transfer Project. These three types of formworks are compared in terms of constructin techniques and construction cost on basis of the engineering experience. It is concluded that selection of proper formworks for the full-circular cross-section tunnels of water conservancy and hydropower projects has great significance for the construction cost control and the improving of the lining progress.
