In the ongoing construction of the Scaleres tunnel's the Tunnel Boring Machine (TBM) on the Fortezza-Verona line in Italy, SELI Overseas, a specialized subcontractor for the Munich-Verona railway axis project, has successfully completed the assembly of the TBM shields. This collaboration with the Dolomiti Consortium (Webuild and Implenia) saw the completion of the TBM shield assembly just over 9 weeks after commencing on-site activities.
In January, the TBM shields will be transported to their final position, and the assembly of the backup gantries will take place directly in the prepared launch cradle for the excavation of the 15.4 km Scaleres tunnel. The Scaleres tunnel has two construction windows, Forch and Albes, which will be constructed using conventional methods. These windows can expedite the construction of the main tunnel during its construction phase.
The first section, spanning from Fortezza/Franzensfeste to the Forch window (3.5 km), is constructed using conventional methods. The second section, from Forch to Albes (8.2 km), involves traditional methods for the initial 200 m, followed by TBM for the remaining distance. The third section, from Albes to the southern entrance (3.7 km), is again being realized with conventional methods.
The 22.5 km construction lot 1, extending from Fortezza/Franzensfeste to Ponte Gardena/Waidbuck, will predominantly consist of tunnels, including the two main double-tube and single-track tunnels, Scaleres (15.4 km) and Gardena (6.3 km). The Gardena tunnel is planned for complete construction through conventional excavation, with only the access windows at Chiusa and Funes utilizing TBM. Roughly 40% of the tunnel construction employs TBM, while the remaining 60% is carried out through traditional methods. Additionally, lot 1 includes two single-track tunnels connecting the new line to the existing line at Ponte Gardena station.
