高喷注浆技术在尼那水电站围堰防渗工程中应用的难点与对策

DIFFICULTY AND COUNTERMEASURE OF HIGH PRESSURE JET GROUTING TECHNIQUE IN COFFERDAM ANTISEEP CONSTRUCTION OF NINA POWER ATATION

较成功地运用了高喷注浆技术处理卵砾石层的防渗问题 ,达到了设计要求标准 ,满足了基坑开挖条件 ,同时也填补了在这项技术领域的空白 ,对高喷注浆技术的经验管理和质量控制 ,也是值得借鉴和推广的。

High pressure jet-grouting technique is well used to deal with antiseep problems in gravel layer. It reaches design standard, meets the requirement of foundation pit excavation and fills the gap in this field. Experience mangement and quality control for high pressure jet-grouting technique are used for reference and spread.
