摘要
依托开封市某人防工程,对高水位下,水源补给充足,强渗透性粉土粉砂地层中深基坑工程的止水方式进行研究,提出较适于上述地层的深层水泥土搅拌桩加竖向注浆止水技术。结合现场监测数据,分析了该技术实施的可行性、操作流程、可能遇到的问题、解决办法及工作原理。工程实践表明,该技术实施效果良好,取得较好的经济与社会效益。
Based on a civil defence project in Kaifeng, the sealing program of deep foundation excavation engineering in strong permeable silty soil strata with high water level and sufficient water supply was researched. A reliable waterproof technology of deep mixing eement soil pile and vertical grouting was proposed. Combining with field monitoring data, this paper analyzed the implementation feasibility of this technique, its operational procedures, possible problems and corresponding solutions as well as the working principle. Engineering practice shows that this technology has good effect and achieves good economic and social benefits.
