Seismic reinforcement pile construction under bridge girders | SPACE21 method
"Seismic reinforcement of bridges in Shizuoka" has overcome challenges related to restrictions in the upper space and the transportation of materials to the excavation bottom. The use of ultra-compact machinery for multi-joint construction has helped reduce temporary facility costs.
This is a case study of the construction of foundation piles for seismic reinforcement work on the Hanishigawa Bridge of National Route 1. In response to the challenging site conditions of a low headroom environment under the bridge girder and the narrow construction base for excavation down to the footing bottom while constructing reinforced earth walls, the "SPACE21 method" was introduced. ■ Space-saving: The compact machine, measuring a maximum of 2.8×2.2×2.0m, can be easily transported to the excavation bottom surrounded by reinforced earth walls. ■ Cost reduction: The leaderless design eliminates headroom loss, enabling the construction of 8 to 18 short, multiple connections under the girder. ■ Improved construction efficiency: Self-propelled movement allows for the rapid installation of 10 foundation piles even in limited spaces. ■ Wide adaptability: The method reliably accommodates heavy steel pipe piles with a diameter of 800mm and a length of 34.5m, as specified for this project. ■ Proven track record: In infrastructure development commissioned by the Chubu Regional Development Bureau, a safe and reliable bearing capacity was established. *For more details, please download the materials or feel free to contact us.
