隔河岩工程帷幕灌浆效果物化检测研究

Physico Chemical Detection on Effect of Curtain Grouting in Geheyan Project

采用物化综合检测技术，对隔河岩工程帷幕灌浆部位所取芯样进行了化学分析和矿物成分、微观结构及微区元素等项试验研究。结果表明：经高压灌入岩石裂隙、断层和粘土中的水泥浆体水化较完全，结石与岩石、粘土胶结良好，灌浆处理后所取试样物理化学性能得到改善，防渗帷幕质量达到设计和施工要求。

Using physico chemical comprehensive detection technology, the chemical analysis, mineral constituents, microstructures and microelements of the samples taken from curtain grouting in the Geheyan Project were studied. The results indicated that the hydration of cement paste injected in the cracks of rock, faults and clay is enough complete, the cement paste is bound well with rock and clay, and the physico chemical properties of the sample after grouting have been improved. The quality of the anti seepage curtain has achieved design and construction requirements.
