Underground structural work including prefabricated elements associated with piles and a process for its production

摘要: An underground structural work, particularly for forming tunnels, underpasses, carparks or the like, includes a pair of containment structures which extend along two opposite sides work. These include pile elements capable carrying deck work formed by substantially vaulted sections transversely structure. In at least some there is incorporated prefabricated supporting element an elongate reinforcement and concrete body anchored to reinforcement. Each section defining side portions central portion can be interposed between them. Between lateral bodies are free spaced allow casting in situ mutual anchoring.
