The system comprises an annular drainage pipe arranged along the cross section of a tunnel and longitudinal drainage pipes arranged on the two sides of the tunnel. The bottom of the annular drainage pipe is communicated with the longitudinal drainage pipes, the longitudinal drainage pipes on the two sides are communicated to the central drainage pipe through the transverse drainage pipes, the longitudinal drainage pipes are integrally of a zigzag structure, the longitudinal drainage pipes on the two sides of the bottom of the annular drainage pipe are distributed in an inverted-V shape, and the longitudinal drainage pipes on the two sides of the transverse drainage pipes are distributed in a positive-V shape; the transverse drainage pipes on the two sides of the central drainage pipe are distributed in a V shape. And a crystal removal device is arranged on the transverse drainage pipe and is an ultrasonic vibration crystal rem |
