摘　　要：坝体防渗注浆工艺是提高坝体安全性能的基础。本文以某排土场污水库坝体防渗注浆为例描述了其注浆工艺。结果表明:“自上而下—分段—孔口封闭注浆法”的注浆质量好,对破碎带、裂隙等的充填效果好,浆液扩散效果好,可以在坝体形成一道帷幕,对坝体渗漏起到了很好的隔离作用。因此,该技术方法可以应用于相似类型的坝体的防渗注浆施工中。Anti-seepage grouting process is basis of improving safety performance of dam body,this paper took a spoil bank as example,described anti-seepageg routing process for dam body.Results showed that grouting method of top-down,segment,hole sealing appeared good grouting quality,with good filling effect on broken belt and cracks.Good slurry diffusion effect causeda curtain formation in the dam body,playing a good isolation role for dam body seepage.Therefore,the technical method could be applied to anti-seepage grouting process for similar dam body.
