ARGE H2 Tunnel Brixlegg
G. Hinteregger &Söhne
Open drainage during the tunnel heading. The ARGE H2 Tunnel Brixlegg is building the 4,200 m long railway tunnel in a construction time of 20 months. In order to keep to this schedule, up to five headings will be worked at the same time. The 2,276 m long exploration gallery, which was completed in 2001, serves in part for supplying the headings. In the course of the work the exploration gallery will be enlarged to serve as a rescue gallery. In addition the creation of a 330 m long access gallery from the centre of Brixlegg is planned. Crosscuts at intervals of 500 m are being constructed.
Use of submersible pumps of type KTZ32.2, these operating in 24-hour snore mode.
Thanks to their special properties including their internal rotating mechanical seal and upstream shaft protection sleeve with seal, these Tsurumi pumps can be operated in 24-hour snore mode.
