[Grid Metal Method Case Study] Nyu-no-ki Bridge Bridge Repair Work
Design load T-25 compatible and road width expanded to 8m! Repair and reinforcement work on the bridge using grid metal.
We would like to introduce a case study of the "Grid Metal Method" that our company handles. We conducted bridge repair work on the Nyu-no-ki Bridge, a first-class bridge built in 1964, located on National Route 120. To accommodate the design load from T-20 to the current standard of T-25 and to widen the road from 7.7m to 8m, we reinforced the floor slab. Grid metal was placed in the cantilevered portion. 【Case Overview】 ■ Project Name: Bridge Repair Work on Nyu-no-ki Bridge, National Route 120 ■ Client: Tochigi Prefecture, Nikko Civil Engineering Office ■ Construction Scale - Floor slab thickening work: 578m2 (of which, grid metal placement 244m2) ■ Construction Period: April 2020 to March 2021 *For more details, please refer to the PDF materials or feel free to contact us.
