[0002] A tunnel is a structure built underground, underwater or in a mountain for laying railways or building roads for the passage of motor vehicles. According to its location, it can be divided into three categories: mountain tunnels, underwater tunnels and urban tunnels. Mountain tunnels are those that pass under mountains or hills to shorten the distance and avoid steep slopes. Underwater tunnels are those that pass under rivers or on the seabed to cross rivers or straits. Urban tunnels are those that pass underground in cities to meet the needs of railways passing through large cities.

[0003] Water seepage may occur during tunnel construction. Water leakage is one of the most common hazards in tunnels around the world. Tunnel water leakage will have adverse effects and even threaten the stability of the tunnel, the safety of facilities inside the tunnel, the safety of external vehicles, the buildings on the ground and the water environment around the tunnel.
