[Scaffolding Construction Achievements] Kiso River Ohashi Bridge (Downstream)・Ibi Nagara Ohashi Bridge (Downstream)

When moving the "rack scaffolding" over the bridge pier to change the floor, there was no need for road restrictions or barges at all!

We would like to introduce our construction achievements in the inspection work for the Kiso River Ohashi Bridge (downstream) and the Ibi Nagara Ohashi Bridge (downstream). Both bridges have an upper structure type of "lower chord simple steel Warren truss bridge," with 12 spans and 14 spans, respectively. It was necessary to complete the inspection work quickly, but the main structure posed obstacles, making it difficult to use bridge inspection vehicles. Therefore, we adopted a method of installing a "rack scaffold" movable floor on the high water bed and conducting the inspection work while shifting it for each span, progressing all the way to the opposite bank. When shifting the movable floor over the bridge piers, there was no need for road restrictions or barges, so there was almost no impact on users. *For more details, please refer to the PDF document or feel free to contact us.
