At the Orsara tunnel construction site, the Marina TBM is advancing rapidly with the excavation and simultaneous lining of the even tube.
Meanwhile, in Bovino (province of Foggia), the assembly operations of the second TBM which will take care of the excavation of the odd tube continue.
The main drive, the main thrust motor of the cutter, whose task is to generate the force necessary to advance the machine across the ground, is currently being installed.
The tunnel, especially given the geological and geotechnical context in which it will be built, will be an extremely complex underground construction.
The Orsara tunnel, 9,871 meters long, will be a strategic work for the upgrading of the Naples-Bari high-speed railway line as well as a crucial project for improving connections in Southern Italy.
