Construction Case: Togawa Ohashi Bridge
Adopting a structure that considers maintenance and repairs after use! Connecting to the future with a durable and long-lasting bridge.
The "Toga Ohashi" is located in Toga Village, Nanto City, spanning the first-class river Shogawa (the dam lake of Komaki Dam) and is a steel arch bridge of the through arch type. The arch section of this bridge is primarily composed of pipes with a diameter of 1 meter. The pipes are manufactured (pipe formation) by gradually bending steel plates using a press machine. The maximum plate thickness of the pipes is 93mm (at the base of the arch of Pier P3), and the thickness decreases towards the top. A press machine weighing 10,000 tons was used to press the pipes at intervals of about 40mm, gradually shaping them into a perfect circle. 【Overview of the Superstructure】 ■ Type: Steel through arch bridge ■ Bridge length: 368.0m ■ Span lengths: 27.2m + 28.0m + 205.0m (arch 190.0m) + 36.0m + 36.0m + 34.2m ■ Road width: 8.5m to 9.5m ■ Steel weight: Approximately 1,725t ■ Scope of work: Factory production, erection, on-site painting, composite deck slab, bridge accessories work, painting work *For more details, please refer to the PDF document or feel free to contact us.
