为了评价帷幕灌浆效果，将数字钻孔摄像技术应用到小浪底水利枢纽3号灌浆洞3个灌浆质量检查孔中。
In order to appraise the quality testing of grout curtain, digital borehole camera technology is applied to three boreholes of the grouting gallery no. 3 in Xiaolangdi Water Control Project.
为确定在这种复杂地层条件下进行钻孔高喷灌浆时采用的合理的工艺工序和技术参数，在高喷灌浆正式开工前进行不同孔距、不同高喷参数的灌浆试验。
The spouting tests with different bore distance and high pressure coefficient were done before working in due form in order to confirm rational working procedure and technical parameter.
