Post-construction anchor bolt installation support method "Anchor Takeru Method"

Achieve high construction precision! Introducing installation aids convenient for the installation of various anchor bolts.

The "Anchor Taker Taro Method" is a post-construction anchor bolt installation assistance method utilizing spacer and stopper functions. Thanks to the stopper function, temporary fixing of the anchor bolts is unnecessary even before the adhesive strength develops. Additionally, the spacer function ensures that the anchor bolts are automatically positioned at the center of the hole, regardless of the installation direction, achieving high construction accuracy. Yoshimitsu Steel Pipe Co., Ltd. is a member of the Anchor Taker Taro Promotion Council. 【Features】 ■ Convenient for the installation of various anchor bolts including fully threaded bolts and deformed rebar ■ Easy and accurate installation and construction by anyone ■ No need for temporary fixing of anchor bolts ■ Temporary fixing work can be performed simultaneously with the insertion of anchor bolts ■ Reduction of construction time through labor-saving Customers wishing to purchase or request a quote are encouraged to visit the Yoshimitsu Steel Pipe access home (link below).

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.

Pavement Assistance Method "Safety Flat P·B Method"

Durable paving is possible! Auxiliary methods for pavement repair work that achieve shortened construction periods and cost reduction.

The "Safety Flat P.B Method" is a pavement auxiliary method that involves burying manhole covers beneath the pavement before the paving work. Since it allows for uniform compaction, it offers excellent durability and enables high-quality, flat pavement without any steps. As a result, maintenance and repairs are reduced, allowing for a decrease in running costs. 【Features】 ■ Achieves shortened construction time and cost reduction ■ Ensures the safety of road users ■ Enables durable pavement ■ Provides a comfortable road surface without noise or vibration *For more details, please refer to the PDF document or feel free to contact us.

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.

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 a "Dedicated Guide Support" with a dedicated guide pipe installed to facilitate the placement of AGF steel pipes for pre-tensioning 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 pipes, and since the pipes are left in the ground without cutting, there is no industrial waste generated. 【Features】 ■ Improved construction precision ■ Tension reduction effect ■ Reduction of industrial waste ■ Reduced cycle time *For more details, please refer to the PDF materials or feel free to contact us.

Tunnel excavation auxiliary method "Slit Injection Fore-Polling"

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

The "Slit Injection Forepoling" is a tunnel excavation auxiliary method that allows for the insertion of a cuttable bolt at a low angle from beneath the support structure into areas of concern for rockfall, such as uncemented 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 is highly effective for ground improvement. 【Features】 ■ The slit processing of the bolt allows for the removal of the bolt's end. ■ It enables insertion from beneath the support structure, proving particularly effective in uncemented ground such as sandy hills, demonstrating higher effectiveness than conventional methods. ■ Since it involves pouring from beneath the support structure, it suppresses leaks caused by roughness in the boreholes through pouring from the position of the sprayed concrete, allowing for reliable injection. *For more details, please refer to the PDF document or feel free to contact us.
