Construction is possible even in narrow spaces such as under railway viaducts! Steel plate wrapping vertical reinforcement method using lifting.
The "RSP Lift-Up Method" is a construction technique that allows for the installation of steel plate wrapping in a narrow working space without the need to demolish or remove nearby structures. Reinforced steel plates that have been divided are assembled on the ground, and using an electric hoist installed on top of the bridge pier, the reinforced steel plates are lifted. By repeating this process of lifting and assembling the next reinforced steel plate underneath the lifted one, the reinforced steel plates are installed on the bridge pier. Additionally, if the footing is located underground and excavation is not possible, the use of the pier-reflection method for the press-in section allows for the installation of steel plate wrapping without excavation. 【Features】 ■ Construction is possible with a working space of about 1.0m ■ No need for demolition or restoration of nearby structures ■ Excellent cost-effectiveness ■ Minimizes social and business losses for facilities under elevated structures ■ Uses small, divided materials, eliminating the need for large heavy machinery *For more details, please refer to the PDF document or feel free to contact us.
