The second Tari bridge is a simple active load synthetic girder bridge built on National Route 183 in 1972. 47 years have passed since the start of service, during which seismic measures and expansion and contraction device water stopwork, floor plate reinforcement by repair and carbon fiber adhesion method of pavement and waterproofing (Heisei 13-14 years) has been made. In the periodic inspection carried out in FY2012, the degree of change III or more was confirmed, and a wide range of floats were confirmed in the carbon fiber adhesive portion. The text is intended to report the re-reinforcement work by resin injection combination type lower surface thickening method.
