复合膏浆材料在溶洞灌浆中的应用研究

Research on Application of Composite Paste Material in Grouting of Karst Cave

岩溶地区水库建设与坝堤加固面临的一个亟须解决的问题是岩溶渗漏问题,岩溶区帷幕注浆是解决该问题的一个有效方法。岩溶区帷幕灌浆使用较多的为纯水泥浆液、水泥粘土浆液和水泥砂浆液等材料。本岩溶帷幕灌浆工程以受灌区实际的工程条件、水文条件和地质条件为依据,采用了复合膏浆对渗漏段进行灌浆防渗处理,现场检测结果显示灌后防渗效果良好,对复合膏浆材料在岩溶地质条件下的防渗处理类似工程具有一定借鉴指导意义。

Karst leakage is an urgent problem to be solved in reservoir construction and dam reinforcement in karst area.Curtain grouting in karst area is an effective method to solve this problem..Curtain grouting in karst areas uses pure cement slurry,cement clay slurry,cement mortar and other materials.The karst curtain grouting project is based on the actual engineering conditions,hydrological conditions and geological conditions of the irrigated area.The compound paste grout is used for grouting anti-seepage treatment on the seepage section.The similar engineering of anti-seepage treatment of grout materials under karst geological conditions has certain reference and guiding significance.
