Can be used in conjunction with anti-corrosion methods! Understand structural dimensions, deterioration conditions, and soil conditions through current surveys and existing document investigations.
The "Manhole Seismic Reinforcement Method" is a technique that addresses the seismic reinforcement of unreinforced manholes (primarily circular) using a seismic reinforcement system (seismic calculations) and carbon fiber (seismic reinforcement). It achieves significant cost reductions and can also be used in conjunction with anti-corrosion methods (coating type). This method complies with the "Guidelines and Explanations for Seismic Measures for Sewer Facilities 2014 Edition (Japan Sewer Association)." 【Features】 ■ Significant cost reduction ■ Adoption of a seismic reinforcement system (seismic calculations) and carbon fiber (seismic reinforcement) ■ Applicable to seismic reinforcement of unreinforced manholes (primarily circular) *For more details, please refer to the PDF materials or feel free to contact us.
