PRECAST PRESTRESSED REINFORCED CONCRETE BOTTOM PLATE, BRIDGE PROVIDED WITH IT, AND EXECUTION METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a precast prestressed reinforced concrete bottom plate which can be easily adapted to a bridge of large bridge width because of ease in transportation and handling. SOLUTION: A reinforced concrete slab is divided and installed on the casting mold 100 of the bridge in the bridge axis direction and the direction at right angles to the bridge axis. Then both ends of the reinforced concrete slab are placed on the casting mold, and are integrated with the casting mold. Then at least one or more sheath pipe 204 is buried to which prestressed concrete strand is inserted from outside in the direction at right angles to the bridge axis within the slab.
