Tunnel auxiliary construction method "Trevi Tube Method"
Select drilling and injection methods according to ground conditions! Construction is possible in various types of ground.
The "Trevichube Method" uses specialized machinery from the Italian company Trevi to install long steel pipes around the perimeter of the tunnel excavation cross-section, while performing injections adapted to the geological conditions, thereby forming a reinforced improved arch zone with the steel pipes. Depending on the geological conditions, drilling and injection methods can be selected, allowing for construction in various geological environments. Compared to the AGF method (φ114.3mm), this method allows for the use of thicker and larger diameter steel pipes, enabling the creation of a significantly rigid improved area, and it can accommodate long drilling of over 20 meters. 【Specifications】 ■Applicable steel pipes: φ114.3 to 139.8 (t=6.0 to 11.1mm) ■Maximum installation length: 50m ■Standard steel pipe length: 6 to 12m/pipe ■Standard installation pitch: @300 to 600mm *For more details, please refer to the PDF document or feel free to contact us.
