帷幕注浆的应用

The application of purdah injecting

结合老虎沟隧道工程,根据不同的地下出水情况,成功地建造了不同的止浆岩盘,运用帷幕注浆完成了隧道的堵水工作,制止了地下水的流失,为进一步推广这一技术提供了理论参考和实践经验。

Combined with Laohugou tunnel project and according to the different underground water yielding, it builds the different sealing batholite, finishes the water stopping by using purdah injecting, and stops the leakage of the underground water, and this supplies theoretical reference and practical experiences to further extend the technique.
