"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.

• Earthquake-resistant construction method

The "NS Cutting Method" is a seismic retrofitting technique that installs seismic flexible joints (secondary products) at the connection points between existing pipes and rehabilitated pipes (composite pipes) and manholes, assuming Level 2 seismic motion. It is a method for enhancing the seismic resistance of existing pipes and rehabilitated pipes (composite pipes) against extraction, protrusion, and bending. This method can be implemented without regard to the construction procedures before and after pipe rehabilitation, minimizing traffic disruption in a compact work area, and allowing for safe and smooth construction through remote operation using a control panel installed on the ground. 【Scope of Application】 ■ Applicable Pipe Types - Reinforced concrete pipes, ceramic pipes - Rigid PVC pipes, rehabilitated pipes (composite pipes) ■ Applicable Pipe Diameter: 200 to 700 mm ■ Applicable Manholes - Oval: 900 × 600 mm - Inner Diameter: 900 to 1500 mm - Wall Thickness: 250 mm or less - Manhole Cover Rating: 600 or more *For more details, please download the PDF or feel free to contact us.
