MANUFACTURING METHOD OF CONCRETE SEGMENT FOR BRIDGE USING UP-DOWN POSITION CASTING

A manufacturing method of a segment of a bridge superstructure by disposition of overturning directions is provided to install a form apparatus for manufacturing a segment effectively, and to deform a form apparatus easily and to manufacture a segment even if the thickness of a bottom plate is enlarged by the change of the cross section of a segment like a segment of a support. A manufacturing method of a segment of a bridge superstructure by disposition of overturning directions manufactures a segment in the overturning direction to locate a bottom plate of a segment on the upper part by installing a form apparatus(13) for the top of an upper plate of a side wall of a segment(100), an internal form apparatus(11) for the internal shape of a segment, and a front and rear form apparatus(14) for the front and rear sides of a segment on a bottom platform(20) manufactured horizontally not to vary the height, and placing concrete.
