INNOVATIONS IN CONSTRUCTION METHODS FOR NEW JUNCTIONS OF MILAN METRO

After having indicated the present make-up of the underground network of Milan and its extensions being constructed at the present time, the author describes the methods used by the new manufacturers, in highly urbanized areas: 1) Earthwork under a cover supported by metallic beams in three parts making it possible to reduce the disturbance caused to automobile traffic. The cover was even built by means of prefabricated slabs in concrete constituting a built-in framework. 2) Previous consolidation of low coherency lands by means of injections of cement mixes, and then of sodium silicate and a catalyst. 3) Covering of dug walls by means of air projected concrete.
