CONSTITUTION: The reinforcing structure for a bridge(100) comprises a pier(101), many steel I-beams(103), many shoes(104) installed under the steel I-beams(103) to be expanded/contracted by load added to the steel I-beams(103), an upper slab(102), many steel I-beams(109) installed on the upper side of shoes(106), many shoes(106) installed between the existing shoes(104), many fixing projections installed on the steel I-beams(109) to couple with set anchor bolts, many set anchor bolts fixed to the lower side of the upper slab(102) to couple with the fixing projections by binding with reinforcing bars, many reinforcing steel bars installed on both side walls of the steel I-beam(109), a steel wedge for tensing/compressing the steel I-beam(109), a form installed along the bridge(100) to support shrinkage compensating grouting materials when injecting to the form, and many bracings for reinforcing/bearing each steel I-beam(103,109).
