STEEL SHELL FOR FOOTING FOUNDATION, STRUCTURE OF BRIDGE, CONSTRUCTION METHOD OF BRIDGE, AND CONSTRUCTION METHOD OF GRADE SEPARATION VIADUCT

摘要

PROBLEM TO BE SOLVED: To provide a steel shell for a footing foundation applied in constructing a grade separation viaduct at an existing intersection to contribute to relief of traffic congestion, shortening of a construction period and reduction of a construction cost, and to provide the structure of a bridge, a construction method of the bridge, and a construction method of the grade separation viaduct. SOLUTION: The steel shells 21a, 21B of approximately box shape for the footing foundations are used to construct the footing foundations 2A, 2B of steel bridge piers 3A-3C. The steel shells 21A, 21B are constituted to allow concrete 22 to be filled after mounting the steel bridge piers 3A-3C and to have strength and support areas that can support the load of the steel bridge piers 3A-3C and bridge upper works 4A, 4B, 4E, 4J laid thereon.
