PROCEDURE FOR THE CONSTRUCTION OF A BRIDGE OF CONCRETE ARMED WITH A LOADING REINFORCEMENT AND BRIDGE THEREFORE OBTAINED.

摘要

In a method of constructing a reinforced concrete bridge a supporting arch is erected which comprises a cocked center part of which forms a supporting reinforcement intended to be incorporated in the concrete of the final bridge structure. Shuttering is placed in position on the arch and the concrete poured to embody the supporting reinforcement and constitute the deck of the bridge. The resultant deck is formed by a ribbed slab, by girders connected by a slab, or by at least one box. After the concrete has hardened the remaining exterior part of the arch is removed, and if required additional reinforcement may be embodied in the concrete.
