The "AS345 Bolt/AS345 Coated Bolt N Type" is a threaded rod steel and reinforcement material that allows for reliable rust prevention treatment of the head using a bell cap. It is designed to accommodate long-term curing of the head, and the bolt sizes available are D19N, D22N, D25N, and D29N. Additionally, it is suitable for long-term storage, and its durability is enhanced by the hot-dip galvanized rust prevention treatment. Furthermore, being fully threaded improves workability. 【Features】 ■ Improved workability due to full threading ■ Reliable rust prevention treatment of the head using a bell cap ■ Enhanced durability through hot-dip galvanized rust prevention treatment ■ Suitable for long-term storage ■ Accommodates long-term curing of the head *For more details, please download the PDF or feel free to contact us.

We would like to introduce the "OSDP Lock Bolt" handled by Okabe Corporation. We offer OSDP rods and OSDP plated rods, with a screw diameter of 28.5mm, a hollow diameter of 13mm, and a yield load of over 196kN. Since the drilling rod can be directly used as a lock bolt, it eliminates the need for rod recovery and lock bolt insertion work. This is particularly advantageous not only in terms of workability but also in terms of cost-effectiveness for unsupported ground. 【Specifications (excerpt)】 ■ Screw diameter: Rope screw 28.5mm ■ Hollow diameter: 13mm ■ Yield load: Over 196kN ■ Tensile load: Over 245kN ■ Material: S45CTK *For more details, please download the PDF or feel free to contact us.

We would like to introduce the 'AS Packer' handled by Okabe Corporation. This product is a grout injection packer that can reliably inject into fractured rock formations and water-bearing layers. The AS Packer's tip is sewn, making it easy to attach to rock bolts. 【Specifications (partial)】 ■ Applicable rock bolts: D19 to D29 ■ Material: Polypropylene fiber ■ Shape: Seamless *For more details, please download the PDF or feel free to contact us.

The "Geometry Panel" is a rock bolt pressure plate that is expected to reduce CO2 emissions through full greening. It can contribute to shortening construction periods simply through transportation and installation. Its application range includes stabilization work for cut slope surfaces, measures against natural slope collapses, measures against collapses in steep areas, reinforcement work for existing retaining walls, and reinforcement work within frame boundaries. Additionally, we provide a mat that allows for easy adjustment of unevenness in our product. If partial adjustments are needed, we have dedicated auxiliary materials available, so please feel free to consult with us. 【Features】 ■ Expected to reduce CO2 emissions through full greening ■ High load-bearing capacity due to its steel construction ■ Recyclable as a resource due to its steel construction ■ Can contribute to shortening construction periods through transportation and installation alone *For more details, please download the PDF or feel free to contact us.

"Soil Guard" is a joint component with drainage functionality that connects rigid polyvinyl chloride pipes (VP pipes according to JIS K6741). It is mainly used in the sediment areas of slopes, and by suppressing the rise of infiltrated groundwater, it enhances the stability of the slope. Additionally, compared to commonly used VP perforated pipes, it is less likely to become clogged with sediment, resulting in reduced maintenance cleaning frequency and lower lifecycle costs. 【Features】 ■ Reduced likelihood of sediment clogging during drainage, increasing sediment discharge suppression effect ■ Lightweight and easy to handle, improving workability ■ Reduced maintenance cleaning frequency, enhancing cost-effectiveness *For more details, please download the PDF or feel free to contact us.

The "Ace Sheet" is a transparent protective sheet for slopes and similar areas that allows for a quick visual check of sediment runoff and muddy water conditions caused by rainfall and other factors. It is UV-resistant, lightweight, and durable. Additionally, it maintains the landscape and is recyclable. It is recommended for use in slope and bare land protection, rain protection after seed spraying, and protection of materials and supplies on site. 【Features】 ■Improves germination after seed spraying (good light permeability) ■UV-resistant ■Easy to install ■Lightweight and durable ■Allows for a quick visual check of sediment runoff and muddy water conditions caused by rainfall *For more details, please download the PDF or feel free to contact us.

The "Bell Cap BC/Bell Cap" is a cap for rust protection of lock bolt heads. The "Bell Cap BC" is pre-filled with Bell Coat (rust prevention oil), so simply peeling off the sheet and attaching it ensures reliable rust protection for the lock bolt head. Additionally, since there is no need for filling the Bell Coat, work efficiency is improved, and there is no waste from the Bell Coat container. 【Features】 ■ Ensures reliable rust protection for lock bolt heads ■ Easy angle adjustment ■ Usable for lock bolts with a diameter of D32 or less and PC steel rods ■ Improved work efficiency for rust protection of lock bolt heads ■ Lightweight and high strength *For more details, please download the PDF or feel free to contact us.

The "Stone Masonry Retaining Wall Seismic Reinforcement Method" contributes to the preservation of cultural heritage stone walls and stone masonry retaining walls with seismic reinforcement technology that balances safety, security, and aesthetics. The "Buttress Type Reinforcement Anchor Method" is a composite method that performs seismic reinforcement while maintaining the current state of stone masonry retaining walls without compromising their appearance, even when deformation or bulging is observed. Additionally, there is the "Clara Method," an aesthetically superior seismic reinforcement method that does not expose the surface of the retaining wall. 【Features】 ■ Buttress Type Reinforcement Anchor Method - A highly seismic-resistant composite method that combines buttress anchors and columnar structures. ■ Clara Method - An aesthetically superior seismic reinforcement method that does not expose the surface of the retaining wall. *For more details, please download the PDF or feel free to contact us.

The 'Drainage Unit' is a site-applied type of slope drainage unit. It features a flexible wire mesh, making it easy to process on-site. It can be used for various applications such as small steps, slope shoulders, and vertical drainage. Additionally, when using vertical drainage, there is also the 'HJ Spacer' that can be fixed without tipping over. 【Features】 ■ Site-applied type ■ Usable for various applications such as small steps, slope shoulders, and vertical drainage ■ Each component is lightweight, allowing for manual transportation and installation ■ Flexible wire mesh makes on-site processing easy *For more details, please download the PDF or feel free to contact us.

We would like to introduce a new method called the "Reinforced Frame Method" as a countermeasure against the aging of the Free Frame Method, which is one of the slope protection construction methods. Since its release in 1975, the Free Frame Method has seen the passage of time, and the need for aging countermeasures has increased. Additionally, it has become necessary to consider measures against changes in the ground, such as weathering and erosion. Therefore, when the ground deteriorates, it is essential to implement reinforcement measures to address the decrease in slope stability. This method utilizes existing frames to enhance the safety of the slopes when reinforcement is necessary. 【Features】 ■ Increased thickness for enhanced suppression effect ■ Additional installations for improved deterrent effect ■ Significant CO2 reduction effect through the reuse of existing frames We also offer "Gap Filling Material" as a filling material for the hollow space behind the frame. *For more details, please download the PDF or feel free to contact us.
