针对吉音水利枢纽混凝土面板堆石坝工程特点,为了提高大坝坝基的渗透稳定性和基岩的整体性,确保大坝运行安全,通过帷幕灌浆使水工建筑物与地下基岩形成防渗帷幕,构成完整的坝基防渗体系。在工程实施中,通过理论与实际有机的结合,以及各环节的质量控制,防渗帷幕施工效果良好,取得了较好的截渗效果。
In view of the project characteristics of concrete faced rockfill dam of JiYin Water Conservancy Project, in order to improve the seepage stability of dam foundation and bedrock integrity and ensure the dam operation safety, seepage control between hydraulic structure and underground bedrock through curtain grouting Curtain to form a complete dam foundation seepage control system. In the project implementation, through the combination of theory and practice, as well as the quality control of all aspects, impervious curtain construction works well and achieved better penetration effect.
