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 method, 'AGF-S / AGF-P Method'. The "AGF-S Method" allows for the cutting and removal during excavation by providing slit processing at the end pipe of the AGF steel pipe, while the "AGF-P Method" uses a special PVC pipe at the end pipe of the AGF steel pipe. Since it can be poured from the standard cross-section, it offers a reduction in cycle time, improved cost-effectiveness, and enhanced workability compared to widening methods. 【Features】 ■ Can be constructed without widening (no need for pre-widening of the tunnel excavation cross-section) ■ Cutting and removal can be easily done every 1 meter of excavation ■ Construction is possible with hydraulic excavators for tunnels ■ Injection of urethane-based and cement-based materials is possible *For more details, please refer to the PDF materials or feel free to contact us.

FK Mesh Panel Method for Reinforced Concrete Pavement Construction

Labor-saving and improved workability! The "FK Mesh Panel" leads to shortened construction periods.

The "FK Mesh Panel Method" is a groundbreaking technique for shortening the construction process of rebar placement in continuous reinforced concrete pavement using diagonal rebar mesh. There is no need to tie individual rebar pieces, allowing for placement even without rebar workers. The amount of rebar that can be installed per person increases by 2 to 7 times, leading to labor savings. This method is particularly effective in situations where there are restrictions on the rebar placement process due to bad weather or site conditions. 【Features】 ■ By using spiral spacers, there is no need to install continuous spacers before placement. ■ The product length ranges from 5m to 10m, allowing for delivery to the site using standard large vehicles. ■ Construction speed improves by 2 to 7 times, enabling a reduction in construction time. ■ Total cost savings can be achieved through shortened construction periods. ■ Automatic production in a factory with dedicated equipment ensures stable quality of rebar pitch and other specifications. *For more details, please refer to the PDF document or feel free to contact us.

Snake duct construction method

Improved work efficiency! Contributes to the reduction of energy consumption and CO2 emissions associated with transportation.

We would like to introduce our "Snake Duct Method." The Snake Duct refers to a general term for "prefabricated flexible ducts" that have undergone special branching and diameter processing on Fujilex (Super Fujilex). It is suitable for duct systems with many branching points. Additionally, the reduction in connection points decreases air leaks, resolving the complexity of conventional methods and improving workability. 【Features】 ■ Cost Reduction: Compressed packaging (volume ratio of 1/3 or less) ■ Shortened Construction Period: Reduced connection points, lightweight and flexibility ■ Environmentally Friendly: No insulation work required *For more details, please refer to the PDF document or feel free to contact us.

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.

Improved Filling Method for Overlaid Concrete: "Confill Tape Method"

No need for equipment, easy to apply! Enhances the fillability and quality of the lining concrete.

We would like to introduce our method for improving the filling properties of lining concrete, the "Confill Tape Method." Through the non-woven fabric tape, residual air and bleeding water are quickly discharged. The materials are lightweight and flexible, allowing for easy application without the need for equipment. Additionally, during the concrete pouring process, the non-woven fabric integrates with the concrete, eliminating the need for grouting or removal work. 【Features】 ■ Enhances the filling properties and quality of lining concrete ■ Rapid discharge of air and water ■ Integration with concrete ■ Easy installation ■ No need for removal as an obstruction *For more details, please refer to the PDF document or feel free to contact us.

Tunnel excavation auxiliary method "Slit Injection Forepoling"

Reduce surface spalling caused by construction from within the cross-section! Achieve reliable injection through leak suppression.

The "Slit Injection Forepolling" is a tunnel excavation auxiliary method that allows for the insertion of cuttable bolts at a low angle from beneath the support structure into areas of concern for rockfall, such as unconsolidated ground. By performing construction from within the cross-section, it reduces the skin fall that occurs from the top and achieves reliable injection through leak suppression. It excels in ground improvement effects. 【Features】 ■ By processing slits in the bolts, it allows for the removal of the bolt ends. ■ It enables insertion from beneath the support structure, proving particularly effective in unconsolidated ground such as sandy hills, demonstrating higher effectiveness than conventional methods. ■ Since it is cast from beneath the support structure, it suppresses leaks caused by rough holes due to casting from the sprayed concrete application position, allowing for reliable injection. *For more details, please refer to the PDF document or feel free to contact us.
