Rapid Treatment Plan for Water Inrush at Tunnel Face

This type of tunnel engineering problem mainly includes fissure water or cavity seepage at the tunnel face, water leakage through fractures in surrounding rock, pore-pressure water in coarse sandstone formations, and water seepage at concrete lining joints. Significant water seepage at the tunnel face may cause large-scale and deep collapses in surrounding rock, while water leakage from the tunnel roof and sidewalls can seriously affect the quality of shotcrete application and secondary lining construction, ultimately compromising the project's quality and safety.
