Applicable to reinforced concrete pipes! Seismic retrofitting method for rehabilitation pipes and manhole connections using non-excavation.
"Remake Ring" is a seismic retrofitting method that installs flexible joints at the connection between the rehabilitation pipe (self-supporting pipe) and the manhole without excavation, designed to accommodate the extraction, protrusion, and bending of the rehabilitation pipe under Level 2 seismic motion. It is possible to install flexible joints in areas where pipe rehabilitation methods have been completed, as well as in conjunction with the pipe rehabilitation method. This method can be applied to existing reinforced concrete pipes and ceramic pipes. 【Features】 ■ Seismic retrofitting method for the connection between rehabilitation pipes and manholes without excavation ■ Accommodates extraction, protrusion, and bending of rehabilitation pipes under Level 2 seismic motion ■ Construction technology review certification obtained No. 1712 *For more details, please refer to the PDF document or feel free to contact us.
