Abstract:
An underground structural work comprising a pair of containment structures (2) which extend along opposite sides of the work and include elements in the form of piles adapted to bear the thrust of the ground during excavation and construction of the work, said elements supporting a deck (10) formed by prefabricated deck sections extending between the containment structures (2), wherein each of said piles comprises a prefabricated bearing element (3) which includes elongate reinforcement members (4) and a concrete body (5) anchored to the reinforcement members within said bearing element with one end of the concrete body extending beyond the reinforcement members, the concrete body (5) being arranged in axial misalignment with respect to the reinforcement members (4) to define a side space above the reinforcement members (4) adjacent one side of the concrete body (5), each bearing element (3) being arranged so that the concrete body (5) is adjacent the ground toward the outside of the excavation so that the side space faces the excavation, and wherein each deck section is shaped substantially as a vault and includes a plurality of prefabricated concrete elements (13, 15) with the ends of each deck section (13a) being disposed adjacent said concrete bodies (5) in said side spaces, said ends (13a) of the deck section and said concrete bodies (5) being spaced to define free spaces filled with concrete for anchoring the ends of the deck section and the concrete bodies together.
