The groups of trial columns will be located within the area of the Eastern Extension and at the same depth of the future plug. However, they will be executed outside the future zone of the potential Launching Shaft, in order to avoid having non continuous columns within the future plug; as a matter of fact, the trial columns will be tested also through direct coring, and their continuity will be compromised.

In fact, the excavation works inside the eastern extension of the station, potential launching shaft, are done below the water table and the proposed technical solution aims to create a water-tight jet grout plug under the excavation bottom in order to avoid impacts on the natural groundwater system. In particular, the solution avoids creating a groundwater drawdown in the area surrounding the jobsite.
