With the increase of tunnel excavation length and depth, the number of fixed pump stations undertaking the task of water transfer and external discharge is also increased, and the difficulty of external discharge is also increased. Therefore, it is necessary to ensure that all pump stations are in efficient and stable operation state. Otherwise, once a fixed pump station fails, the entire external drainage system in the tunnel will be paralyzed, which will directly cause water backflow, cause the working face to be flooded, and the tunnel to be forced to stop work.
