Whether it's a world record with the longest railway tunnel on earth at the Brenner or the epoch-making Gotthard project: the business of mechanized tunnel boring through hard rock is currently reaching new heights in Europe. Now Scandinavia is discovering the advantages of mechanized tunnelling. With the breakthrough at the Ulriken Tunnel, the first major tunnel project in Norway using a Herrenknecht Gripper TBM has been successfully completed.
The global market leader from Schwanau looks back at decades of experience in tunnelling through the toughest of hard rock: Herrenknecht hard rock machines have excavated around 820 kilometers of tunnels in more than 200 projects since the year 2000. In late August the breakthrough of the Ulriken Tunnel for the expansion of the Norwegian railway network added another hard rock highlight to the list.
In Norway, drill & blast tunnelling traditionally dominates. "The realization that mechanical tunnelling is a real alternative even in the extremely hard rock now seems to be spreading in Scandinavia," says Eric Fourchault, Project Manager at Herrenknecht. Compared to traditional drill & blast, mechanized tunnelling has a number of advantages. It has less impact on the mountain and provides highest safety for the crew, without the shocks of blasting.
The short distance of only 30 meters from the existing operational railway tunnel was therefore decisive for the use of a TBM at the Ulriken Tunnel. Furthermore, machine technology can achieve higher average advance rates, especially over long distances.
