[Scaffolding Construction Achievements] Tomei Ashigara Bridge

We constructed side scaffolding and cantilever scaffolding tailored to the shape under the main girder, achieving improved work efficiency!

We would like to introduce our construction achievements for the concrete spalling prevention measures at the intersection of the down line of the Tomei Expressway (upbound) and the Tomei Ashigara Bridge (PC3 span continuous cable-stayed bridge). The selection of scaffolding was carried out with a focus on ensuring the safety of the traffic on the main line during operation and the structural integrity of the cable-stayed bridge (including the stay cables), while also considering economic efficiency and constructability. Among the comparative proposals, the "Rack Scaffolding Method" was adopted due to its shorter down line restriction days and superior economic efficiency. Since the site is located at a point where it intersects with the down line of the Tomei Expressway, higher safety and reliability were required in planning and execution. In particular, measures against strong winds, earthquakes, and falling objects were implemented by installing additional hanging materials and conducting thorough protective boarding and netting, ensuring the required quality. Additionally, side scaffolding and cantilever scaffolding were constructed to match the shape of the underside of the main girder, achieving improved workability. *For more details, please refer to the PDF document or feel free to contact us.
