Tunnel project of about 8 km, the Group intervened during construction by providing tools that greatly improved the performance resulting in an important change in the progress of work and in the timing.
Submarine tunnel excavated with 3 TBMs. Despite the difficulty of working in particularly difficult conditions and below sea level, the Group has been able to develop special housings for its cutters, allowing the disc cutters replacement to be automatically carried out by special robots.
In order to adapt to the complex geological conditions of the river and the difficulties arising from working under high water pressure, the Palmieri Group has supplied wear-resistant 19 “Monoblock” type cutters thus reducing their replacement to a minimum.
