The "KJS Removal Anchor Method" uses unbonded PC steel strands, integrating the load-bearing body in a U-turn shape at the underground tip, and combines multiple units in the depth direction to create an anchor body with excellent friction resistance against the supporting ground. The anchor input force is evenly divided by the KJS tensioning device DPH and can be transmitted to the supporting ground. This method is highly efficient and reliable due to its ease of conducting suitability tests and confirmation tests before fixation, as well as the ability to remove PC steel strands using mobile cranes or high-speed hydraulic jacks. 【Features】 ■ The load acting on each load-bearing body is uniform due to the DPH (differential tensioning device). ■ The KJS jack allows for continuous execution of pre-suitability tests, confirmation tests, and subsequent anchor fixation. ■ The tendon components are few, making it economical and excellent in workability. ■ The removal efficiency is significantly improved. *For more details, please refer to the PDF materials or feel free to contact us.

The "Anchor Panel" is a pressure distribution plate for ground anchors that combines a fiberglass-reinforced plastic (GFRP) lattice panel with a rigid frame. The rigid frame is protected against corrosion with hot-dip galvanized coating plus urethane paint or polyethylene paint, and the design also takes corrosion protection costs into account. The opening ratio of the pressure distribution surface is over 40%, allowing it to be completely covered in combination with greening work. Depending on the design anchor and soil bearing capacity, it can be selected from 9 standard types, and special sizes can be manufactured according to the pressure distribution area and load. 【Features】 ■ Composite pressure distribution plate combining FRP lattice panel with steel frame (SS400) ■ Opening ratio of over 40%, suitable for greening ■ Lighter and lower in height compared to concrete pressure distribution plates ■ As a secondary product, it does not require a curing period, enabling a reduction in construction time ■ Not limited to specific anchors, can be manufactured according to design loads and dimensions suited to the site *For more details, please refer to the PDF materials or feel free to contact us.

More than 90% of the locations where issues occur in ground anchors are said to be in the head and the back of the head. By repairing these areas, it is possible to improve the corrosion resistance to the level of the current ground anchors. The maintenance and management of ground anchors are carried out in accordance with the "Ground Anchor Maintenance Manual." Maintenance and management consist of three parts: inspection, investigation, and countermeasures. Specialized materials are required to conduct investigations and countermeasures. 【Flow of Ground Anchor Maintenance and Management】 ■ Inspection: Visual inspection of the structure where the ground anchor is installed ■ Investigation: Conducted when abnormalities are confirmed during inspection ■ Countermeasures: Implemented if the investigation results indicate a decline in performance during the service period *For more details, please refer to the PDF document or feel free to contact us.

The "Disc Sensor" is a hydraulic-operated center hole type load cell developed for the purpose of managing residual anchor force in various ground anchor methods. The body of the Disc Sensor is made of stainless steel (SUS316L) and has passed a repeated load test of 100,000 cycles at its rated load. Its structure minimizes changes in the pressure receiving area, resulting in less time-dependent variation and stable load readings over an extended period. Additionally, by housing the thrust pipe behind the anchor head, the protrusion of the anchor head has been reduced. 【Features】 ■ Sleek anchor head ■ Minimal time-dependent variation ■ Reduced load fluctuations due to thermal effects ■ Applicable anchors - Can be used with EHD permanent anchors, Super Flotec's SFL-1 to SFL-4, SEEE, and others. *For more details, please refer to the PDF document or feel free to contact us.

The "Hair Transplant Drainage Pipe" is a product developed to prevent clogging of drainage pipes. It is a pipe in which "piles" are meticulously implanted using "static electricity" in PVC pipes, serving the role of a "filter material," which was previously considered impossible with conventional drainage pipes. This enhances drainage effectiveness while simultaneously preventing clogging of the pipe. It is hoped that this will be adopted and utilized as a method for landslide prevention. 【Features】 ■ Exhibits great power in preventing landslides ■ Enhances drainage effectiveness ■ Prevents clogging *For more details, please refer to the PDF document or feel free to contact us.
