Abstract (en)
The railway tunnel of improved safety is a tunnel of circular section (1) built with a tunnel boring machine, having a slab (3), placed slightly over the bottom of the tunnel, and a separating wall (2), disposed at the middle of the tunnel, forming two independent railway galleries completely isolated, and a service gallery (6), bellow. On the slab (3), close to the circular wall (1), on both sides, fire devices of box type (10) are disposed, which are extended down, forming vertical access galleries (8), to allow for the safe passage of people to the service gallery, in case of accident or fire inside the tunnel. The separating wall (2) disposes of large openings (7), provided with fire doors, regularly spaced along the length of the tunnel, to allow for the passage of the trains from one line to the other, in the case one of the lines became out of service. The service gallery (6) is provided with emergency vehicles of shuttle type (9), to allow for local access of personnel and the safe evacuation of people, in case of accident or fire inside the tunnel.
