We will improve seismic performance! A bending reinforcement method that can be implemented even under conditions where excavation is not possible.
The "Pier Relief Method (Bending Reinforcement Specification)" is a seismic reinforcement method for bridge piers that uses pressed steel plates, which excel in workability and do not require large-scale excavation or earth retention, making it an economical solution for bending reinforcement. The method involves wrapping and pressing segmented reinforcement steel plates, drilling footings in the gap between the reinforcement plates and the existing bridge pier, anchoring axial reinforcing bars, and then filling with concrete to enhance seismic performance. 【Features】 - No need for large-scale temporary works (temporary closures, temporary bridges) - Excellent cost-effectiveness - Low riverbed obstruction rate - Minimizes impact on navigation routes and riverbed - Extremely minimal excavation and residual soil disposal *For more details, please refer to the PDF materials or feel free to contact us.
