NEW TUNNEL "SAN BERNARDINO" ON THE GENOA-VENTIMIGLIA LINE

LA NUOVA GALLERIA SAN BERNARDINO DELLA LINEA GENOVA- VENTIMIGLIA

Tunneling through highly degraded shales, in the presence of buildings existent in vertical with respect to the portal, with an average coverage of about fifteen meters, required the perfectioning of a particular method of construction. This method, based on the construction of a pre-portal, made up of metallic inserts injected with mortar, is briefly described, both with regard to the characteristics and the planning of the project, and with regard to the modalities for its execution. Furthermore, mention is made of the reasons which induced the rejection of defense structures of a different type, such as the underpinning or the consolidation of the terrains involved by means of chemical injections. The works described have been completely carried out, in full compliance with the programs of time and expenditure, and achieving the prime objective of safeguarding the integrity of the buildings located above the tunnel.
