摘　　要：混凝土面板堆石坝帷幕灌浆一般与趾板和面板一起构成挡水建筑物的防渗体系,巴拉水电站混凝土面板堆石坝位于高海拔、高寒地区,受气候条件影响和建设工期限制,必须在当年5~10月完成斜趾板帷幕灌浆。本文从帷幕灌浆钻孔的角度出发,通过理论计算提出了帷幕灌浆钻孔台车的设计方案,使帷幕灌浆钻孔在确保安全和质量的前提下能够快速、高效、低耗地施工,可供类似项目参考。The curtain grouting of concrete faced rockfill dams,along with plinth and concrete face,generally forms the anti-seepage system of water retaining structures.The concrete faced rockfill dam of Bala Hydropower Project is located in a high altitude and cold area,and due to climatic conditions and construction period limits,the curtain grouting of inclined plinth must be completed from May to October of that year.From the perspective of accelerating curtain grouting drilling,this article proposes a design scheme for curtain grouting drilling jumbo through theoretical calculation.The construction of curtain grouting drilling is carried out quickly,efficiently,and with low consumption when the safety and quality are ensured.The practice can provide reference for similar projects.
