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.

The "High-Spec Micro Pile Method" is a small-diameter steel pipe pile method for seismic reinforcement of existing structures. It can be constructed in narrow spaces and is economically advantageous, making it suitable for new construction projects under strict conditions where structures are in close proximity. The construction of this method involves using a boring machine to perform double-tube drilling, erecting the steel pipe, and then filling it with grout to secure the steel pipe in the ground. 【Features】 ■ Can be constructed in low-headroom areas ■ Cost reduction can be achieved ■ Suitable for maintenance work ■ Environmentally considerate construction *For more details, please refer to the PDF materials or feel free to contact us.

The "DCI Multi-Point Injection Method" is a ground improvement technique that can suppress displacement by injecting at low pressure and low discharge. Although the injection speed per pump is low (1 to 6 liters per minute), rapid construction is possible through simultaneous multi-point injection (32 connections). According to the injection pressure, each pump is mechanically and automatically controlled, and flexible injection pipes are consolidated to minimize the occupied area. 【Features】 ■ Construction is possible near and directly beneath existing structures. ■ Rapid construction is possible through simultaneous multi-point injection (32 connections). ■ Construction in narrow areas is possible with a dedicated system (DCI system). ■ Each pump is mechanically and automatically controlled according to the injection pressure. ■ Flexible injection pipes are consolidated to limit the occupied area. *For more details, please refer to the PDF materials or feel free to contact us.

"JPG Plas-ZERO" is a two-shot type of plastic filling injection material that possesses plasticity and non-shrinkage, suitable for filling cavities and gaps. It allows for long-distance pumping of approximately 4,000 meters by mixing equal amounts of the two components at the tip. Depending on the size of the cavity or gap, you can select the gel time at which the injection material becomes plastic. It is resistant to water diffusion and dilution in still water, exhibiting non-separation in water. Additionally, it experiences almost no shrinkage after curing. 【Features】 ■ Low shrinkage and long-distance pumping type ■ Capable of long-distance pumping of approximately 4,000 meters ■ Ability to select the gel time at which the injection material becomes plastic ■ Exhibits non-separation in water ■ Almost no shrinkage occurs after curing *For more details, please refer to the PDF document or feel free to contact us.

Our company employs a technology called "Ultra-Multi-Point Injection Method," which allows for simultaneous injection from multiple injection points using low-output pumps, enabling rapid construction. By arranging a large number of injection nozzles, ranging from dozens to hundreds, in a three-dimensional manner within the ground, and injecting at pressures and flow rates suitable for each point, we achieve ideal permeation injection and high construction efficiency. 【Features】 - Construction is possible near and directly beneath existing structures. - Although the injection speed per pump is low (1 to 6 liters per minute), rapid construction is achievable through multi-point simultaneous injection (32 connections). - A modular dedicated system allows for construction in narrow spaces. - Individual pumps are mechanically and automatically controlled according to the injection pressure. - Flexible injection pipes are consolidated to limit the occupied area. *For more details, please download the PDF or contact us.
