防渗墙钻孔压水原位渗流检测方法由于施工简单、成本低、时间短、对堤坝没有损伤,是一种值得推荐的堤坝防渗墙现场检测方法。为了掌握林州市风门沟水库大坝防渗加固帷幕灌浆效果,采用压水试验对水库大坝防渗加固帷幕灌浆效果进行测试,并对灌浆效果进行了分析。该水库大坝防渗加固帷幕灌浆方法可供其他工程借鉴。 Because of simple construction, low cost, short time and no damage to the embankment, the in-situ seepage flow detection method for seepage prevention wall drilling water pressure is a recommended on-site inspection method for embankment cutoff wall. In order to grasp the curtain grouting effect of dam of Fengmengou Dam of Linzhou City, the effect of curtain grouting of seepage control and reinforcement of reservoir dam is tested by water pressure test, and the grouting effect is analyzed. The dam seepage control curtain grouting method can be used for other projects.
