摘　　要：基于北京市某中型水库渗漏现状,分析渗漏特点,对比分析3种防渗加固方案,从技术方法和方案设计两方面对高喷灌浆施工方案进行介绍,同时从工艺流程及钻孔、浆液配制、喷浆、孔口回灌等对高喷灌浆施工要点进行详细探讨。Based on the leakage status of a medium-sized reservoir in Beijing,the characteristics of leakage were analyzed,and three anti-seepage reinforcement schemes were compared.The construction scheme of high sprinkler grouting was introduced from the aspects of technical methods and scheme design.At the same time,the key points of high sprinkler grouting construction were discussed in detail from the aspects of process flow,drilling,slurry preparation,grouting,and hole recharge.

关 键 词：坝基渗漏 防渗加固 高喷灌浆
