| description | The invention discloses a novel tunnel drainage structure based on the pressure gradient triggering switch principle. The novel tunnel drainage structure comprises longitudinal water collecting pipes,transverse water collecting pipes, an arc-shaped water collecting pipe, drainage pipes, pressure gradient switch structures and drainage ditches, wherein the longitudinal water collecting pipes, thetransverse water collecting pipes and the arc-shaped water collecting pipe are embedded between the inner wall of a tunnel second lining and a rock stratum and mutually communicate; the drainage pipescommunicate with the transverse water collecting pipes; the pressure gradient switch structures are arranged in the drainage pipes; and the drainage ditches are formed in the length direction of a tunnel. The transverse drainage pipes are arranged in the length direction of the tunnel, the arc-shaped water collecting pipe is arranged along an arc of the top of the tunnel, and the drainage pipes communicate with the drainag |
