组合钢模板在金河水电站施工中的应用

Application of combined steel formwork to the construction of Jinhe Hydropower Station

金河水电站引水隧洞全长778.026m,为城门洞形,结构断面尺寸为3.8m×4.0m,通过钢模台车与组合钢模板的技术经济比较,后者一次性投资相对较小,还可重复利用,最终采用了3套组合钢模板浇筑方案,不仅保证了工期,而且取得了质量、安全双赢,得到参建各方的一致好评。

The diversion tunnel for the Jinhe Hydropower Station is 778.026 m lon g and the dimension of the entry is 3.8 m×4.0 m. By comparing the economy and t echnology of steel plate trolley and combined steel formwork, the latter is rela tively small in lump-sum investment and such technology can be used repeatedly. So we adopted three plans of combined steel formwork to the project. The project has been completed in schedule and the quality and safety of the construction a re guaranteed.
