It is a cutting technology for installing seismic-resistant joints.
Our company provides a seismic-resistant flexible joint (secondary product) that can be installed at the connection points between existing pipes, rehabilitated pipes (composite pipes), and manholes without excavation. This method, called 'NS Cutting Method,' is designed to accommodate the extraction, protrusion, and bending of existing and rehabilitated pipes (composite pipes) under the assumption of Level 2 seismic motion. It can be executed regardless of the construction procedures before and after pipe rehabilitation. Additionally, the operation can be performed remotely via a control panel installed on the ground, ensuring safety and smooth execution. 【Construction Steps】 1. Preliminary Confirmation (Investigation Work) 2. Invert Breaking 3. Cutter Blade Replacement 4. Cutting Work 5. Installation of Seismic-Resistant Flexible Joint 6.
