Due to heavy traffic and difficulty in occupying the road, a crab crane is mounted on a spud-type steel barge!
At Yokoyama Bridge on the Tenryu River in Tenryu Ward, Hamamatsu City, Shizuoka Prefecture, the "temporary cutoff LPF method" was implemented. Due to heavy traffic and the difficulty of occupying the road, materials were transported and construction was carried out using a spud-type steel barge equipped with a crab crane. Since the water depth is about 10 meters and the buoyancy is large, a method of filling the space between the liner plate and the footing with water-stopping concrete was adopted. [Case Overview] ■ Temporary cutoff shape: Circular φ9.5m H=12.5m ■ Client: Hamamatsu City (Construction in fiscal year 2017) ■ Construction location: Yokoyama Bridge, Tenryu River, Tenryu Ward, Hamamatsu City, Shizuoka Prefecture *For more details, please download the PDF or feel free to contact us.
