Tunnel auxiliary construction method "AGF-S / AGF-P method"

Injection of urethane-based and cement-based materials is possible! It enables a reduction in cycle time, improved cost-effectiveness, and enhanced workability.

We would like to introduce our tunnel support construction methods, 'AGF-S/AGF-P Method'. The "AGF-S Method" allows for the cutting and removal during excavation by incorporating slits at the ends of AGF steel pipes, while the "AGF-P Method" uses special PVC pipes at the ends of AGF steel pipes. Since it can be installed from the standard cross-section, it offers reduced cycle times, improved cost-effectiveness, and enhanced workability compared to widening methods. 【Features】 ■ Can be constructed without widening (no pre-widening of the tunnel excavation cross-section required) ■ Cutting and removal can be easily done every 1 meter of excavation ■ Construction is possible with hydraulic excavators for tunnels ■ Injection of polyurethane-based and cement-based materials is possible *For more details, please refer to the PDF materials or feel free to contact us.
