摘　　要：该文以长江重要堤防隐蔽工程为实例 ,介绍了水、浆两重管旋喷工艺的特点。实例表明 ,该工艺特别适应作业空间受限地段防渗工程施工 ,且改进后的双液注浆工艺可有效处理复杂地基条件下的地层漏浆问题 ,极具推广价值。Taking the important levee concealed work in Yangtze River as an example,jet grouting technique of double-pipe with water and mortar was discussed.With retrofitted two medium,the practical example showed that the technique was not only especially adaptive to anti-seepage project construction at the limited section,but also effective to treat the problem of mortar leak from soil stratum under the condition of complex foundation,thus it would have great extended value.
