根据白石工程溢流坝反弧面的结构特点 ,经过分析、论证 ,决定采用整体悬挂式双向滑模施工新技术 .该技术工序简单 ,能充分保证反弧面混凝土质量及平整度的设计要求 ;便于安装、施工交替进行 ,确保施工进度 ;解决了 # 6、# 17坝段的端部采用原纵向滑模时 ,不能施工到位的死角问题 ;可节省大量的钢材及木材 ,具有一定的经济效益
According to the structural features of the anti-arc surface of the overflow dam of Baishi Project, the new technology of integral suspended two-way sliding mode construction is determined through analysis and demonstration, which has the advantages of simple process and sufficient design requirements of anti-arc concrete quality and smoothness; Which is convenient for installation and alternation of construction to ensure construction progress; solves the problem of dead spots that can not be put in place when the ends of # 6 and # 17 dam sections adopt the original longitudinal sliding mode; and can save a large amount of steel and timber and has certain economic benefits
