Tunnel auxiliary construction method "AGF-Φ method"
By using a dedicated guide tube, reliability and safety are improved! Furthermore, it achieves a low impact on the environment.
The "AGF-Φ Method" is an expanded type of AGF that adopts the "AGF-Φ Dedicated Guide Support" with a dedicated guide pipe installed to facilitate the placement of AGF steel pipes for pre-loosening suppression by drilling holes in the web section of H-shaped steel supports. By using the dedicated guide pipe, the placement of the steel pipes becomes more accurate, improving construction precision. As construction precision improves, it becomes possible to reliably form an arch crown at the tip of the steel pipe, and since the steel pipes are left in the ground without cutting, there is no industrial waste generated. 【Features】 ■ Improved construction precision ■ Loosening suppression effect ■ Reduction of industrial waste ■ Reduced cycle time *For more details, please refer to the PDF document or feel free to contact us.
