Jinmen tunnel passes through the environmental nature reserve. In the process of construction, many karst caves are exposed and a large amount of water gushes from karst are encountered several times. During the treatment of water inrush, the source and characteristics of water inrush are explored, and several treatment measures such as “advance curtain grouting”, “diameter backward grouting” and “anti water pressure lining” are taken. The engineering practice shows that the treatment technology of karst water inrush adopted by the project is practical and effective, which has certain reference significance for the tunnel construction under the condition of rich karst water inrush.
