Segment production for Lot H41 – automated and tailored to project requirements

For one of the largest construction phases of the Brenner Base Tunnel, a carousel system with nine sets of segment moulds was erected at the Ahrental access tunnel, eight of which were in use and one set was kept in reserve. The system was equipped with automation solutions tailored to the project requirements: a robot took over the mould cleaning and surface finishing, while curing was automatically monitored and controlled by wireless sensors.

 

The concrete was placed via an integrated transport system to the concreting station with automatic mould cover. This enabled the H41 Sillschlucht-Pfons consortium to produce up to 120 segments per day or up to 3384 segments per month. Production was adjusted to the advance speed in each case.

 

Segment production for Lot H53 – flexible and reliable stationary production

For the largest construction lot on the Austrian side, the Max Bögl Group produced over 45,000 segments for the inner lining of the two main tunnels – stationary at the Sengenthal segment factory using equipment from Herrenknecht Formwork. On-site production enabled rapid commissioning and offered maximum scalability. 

 

Since August 2024, around 530,000 tons of segments and precast invert elements have been transported to the construction site by rail – without transshipment, directly on specially constructed connecting tracks.

 

Adaptation to project requirements

No two tunnel projects are alike. This also applies to the individual lots of the BBT.
That is why we always tailor our equipment precisely to the requirements on site.

 

Whether continuous or stationary production, a high degree of automation or targeted individual measures: the decisive factor is what really creates added value in the overall concept of the project.
