摘　　要：辛集橡胶坝工程坝址区存在采砂坑、卵石堆积、局部淤泥、较大卵石或孤块石等地质特点,针对此地质条件,决定采用高压摆喷灌浆截渗技术。文章介绍了橡胶坝截渗墙的设计情况,详述了高压摆喷施工参数试验、施工技术、混凝土截渗墙施工方法、注意事项及建议。工程完工后的钻检查孔、注水试验、地学CT检测,以及截渗墙下游开挖检查证明:混凝土墙体的连续性和完整性较好,未发现薄弱部位,该技术满足设计要求和规范规定,较好地解决了坝基截渗和稳定性问题。Xinji rubber dam project site has geological characteristics of mining pit, pebble accumulation, local silt, larger pebbles or solitary stone, etc. High pressure sprinkler irrigation pulp impervious technique is adopted aiming at geological conditions. In the paper, the design condition of the rubber dam cut-off wall is introduced, construction method,construction technique, concrete cutting wall construction method, precautions and suggestions are describdrilling access hole after project completion, water injection test, geoscience CT detection and impervious wall downstreamexcavation inspection prove that： concrete wall has better continuity and integrity, weak parts are not discovered, thetechnology meets the design requirements and specification regulations, thereby better solving seepage intercepting in damfoundation and stability problems.
