向家坝水电站泄水坝段长陡过流面模板设计及应用

摘要

向家坝水电站二期工程泄水坝段中表孔过流面面积大、坡度较陡、需要大仓位浇筑，并且施工速度及施工质量要求高。施工中采用一种可连续安装或拆卸的长陡过流面模板，操作方便、成本低、周转利用率高，实现了大面积长陡过流面的快速、高质量施工，其模板技术值得推广。%The surface outlet for flow at the outlet dam section of Xiangjiaba Hydropower Project, Phase II, features large area and great steep.Therefore, mass concrete is required.Meanwhile, both construction speed and quality are highly required.During construction, one kind of the formworks which can be installed and dismantled continuously for the long and steep surface for flow is applied.It is convenient to operate, lower in cost and high utilization rate.It materializes the speedy and quality construction of the long and steep surface outlet for flow.The formworks are worth of developing for application.
