Seismic reinforcement method for rehabilitation pipes and manhole connections using non-excavation techniques!
Our company provides a seismic retrofitting method called "Remake Ring," which involves installing flexible seismic joints at the connection points between the non-excavated rehabilitated pipes (independent pipes) and manholes. This method is designed to accommodate the extraction, protrusion, and bending of rehabilitated pipes under Level 2 seismic motion. This method can be applied in two scenarios: one where flexible seismic joints are installed at locations where pipe rehabilitation has already been completed, and another where flexible seismic joints are installed alongside the pipe rehabilitation work. Please feel free to contact us if you have any inquiries. 【Application Scope】 ■ Applicable existing pipe types: Reinforced concrete pipes, ceramic pipes ■ Applicable rehabilitated pipes: Independent pipes ■ Applicable existing pipe diameters: 200 to 700 mm, etc. *For more details, please download the PDF or contact us.
