The micropiles are created in such a way as to create an arch-shaped support structure preparatory to the excavation. To prevent deformations and subsidence from occurring with the extrusion of the core and a general deformation of the cavity, a series of perforations on the excavation face are usually also provided, normally reinforced with GRP pipes. The installation of these pipes (along the arch and on the front) takes place with special machines for tunnels (positioners) which are very stable and equipped with long masts to allow drilling in a single blow . Frequently horizontal columns of soil are created with the same purpose (reinforced jet grouting) .
