Among them, water damage is the most common. Tunnels Leakage occurs to varying degrees. Among them, the leakage of construction joints and deformation joints is the most common. Leakage in the tunnel has a great impact on the safe operation of the tunnel and even endangers the safety of the tunnel structure. At present, most of the leakage treatment is based on the treatment of the leakage site simply by grouting in the cave, slotted drainage, or a combination of the two. However, the existing water blocking structure needs to destroy the secondary lining structure and affect the safety of the structure's use status. It is not equipped with a plugging and drainage combination system and does not achieve natural drainage.
