Kakuta Bridge
The "Kakutahashi Pon! Metal Kit" is a new type of metal deck bridge that involves installing square steel pipes one by one, inserting horizontal steel pipes on-site, and pouring concrete to create panels. It allows for rapid and simple construction by transporting factory-made panel units to the site and integrating them together. Compared to PC bridges, it can reduce the design reaction force of the substructure by about 20%, allowing for a smaller substructure. Additionally, due to its low girder height structure, it is possible to reuse existing substructures during bridge renewal. It is suitable for bridges over urban rivers with girder height restrictions and for bridges that intersect with main roads and railways.
