Terzo Valico dei Giovi - HowWebuild: Mechanized Excavation - Episode 2

The new high-capacity Milan-Genoa line is largely an underground route. Starting from Genoa, the first section, the so-called Valico Tunnel, develops 27 kilometres into the tunnel, making it Italy's longest underground railway route. In reality, if all the secondary line interconnections are also considered, the project involves building 90 kilometres of tunnels.

Most of this journey is made underground. That is why the excavations are a central part of the work. Compared to the total 90 kilometers of tunnels built, 32 of these were excavated with TBMs. The remaining 58 using traditional methods. 

In the second episode of HowWebuild - Webuild's tech video series dedicated to the Terzo Valico project - we discover together the mechanized excavation techniques of a large infrastructure, which will allow trains to travel at a maximum speed of 250 km / h on the Milan-Genoa Line.
