fischer fixings in the Brenner Base Tunnel

Europe's largest infrastructure project to date is in full swing. Since 2007, the Brenner Base Tunnel has been under construction - the longest underground railway connection in the world. Completion is planned for 2027. As part of the new railway line from Munich to Verona, goods and passengers will be transported faster through the tunnel. fischer heavy-duty anchors are used to securely fasten permanent and temporary attachments.

Getting people to their destination faster, shifting freight traffic from road to rail and reducing emissions. With these goals in mind, the Brenner Base Tunnel opens up completely new dimensions. It runs 55 km from Innsbruck (Austria) to Franzensfeste (Italy). It also connects with the existing Innsbruck railway bypass. Adding this section, the Alpine breakthrough is 64 km long in total.
This makes it the longest underground railway connection in the world. Compared to the old Brenner railway line with its uphill and downhill gradients, the tunnel runs flat. This is intended to increase speeds and capacities.

What was fixed with fischer products:

Reinforcing bars, running rails, formwork elements, retaining devices for supply lines and much more.

The centrepiece of the construction of the century are two main tunnel tubes, each with a diameter of 8.1 m, which run next to each other at a distance of 70 m. They will each be equipped for one-way traffic. They will each be equipped with a single track for one-way traffic. At intervals of 333 m, cross passages connect the two main tunnel tubes, which are used as escape routes. In addition, emergency stops increase safety. Four lateral access tunnels lead to the ground surface. Additional connecting tubes create further connectivity. 12 m below the main tunnel tubes and centred on them is an exploratory tunnel with a diameter of at least 5 m. This tunnel is primarily used for rock support. This is primarily used for rock exploration.

Reinforcement bars, running rails, formwork elements, holding devices for supply lines and much more are securely and firmly fixed with fischer fixing systems. Among other things, the fischer injection mortar FIS SB is used. This achieves a very high load level in non-cracked concrete, cures quickly and allows variable anchoring depths for shorter installation times and less material usage. In the Brenner Base Tunnel, the FIS SB is used to create reliable reinforcement connections in the partition walls of the cross passages. In addition, it is installed with various threaded rods, for example, for the rail fastening of the formwork carriage.fischer ULTRACUT FBS II concrete screws are also used for temporary fixings. These are extremely easy to install, very flexible thanks to three screw-in depths and suitable for multiple uses - for example in formwork construction. Practical nail anchors from fischer are also used for temporary fixings.
