长河坝水电站地下厂房岩壁梁清水混凝土施工技术

摘要

岩壁梁是地下厂房重要的构筑物，清水镜面混凝土施工的关键是混凝土配合比和模板。介绍了长河坝水电站岩壁梁施工中，清水混凝土配合比试验、模板工序控制及吊罐入仓、复振和温控等保证混凝土施工质量的措施。%Rock beam is important structure of underground powerhouse. The key points of faced concrete construc-tion are mix proportion and formwork. An introduction was made on the technical measures adopted for the con crete construction quality of underground powerhouse rock beam of Changheba Hydropower Station,including mix proportion test,formwork construction sequence control,hanging pot concreting,repeated vibration and temperature control etc.
