Notice of Participation in the Construction Technology Exhibition "EE Tohoku '25"

Obtained "Construction Technology Review Certification." A pile structure that achieves a small installation area and shortened construction period. Initial installation costs are reduced, making it an economically advantageous countermeasure.

Urban Guard is suitable for debris flow and driftwood measures in non-flowing streams (small-scale streams). It is a construction method that excels in workability and contributes to shortening construction periods. The installation cost is low, and by performing stone removal and other maintenance after installation, it allows for repeated capture of debris flows and driftwood, thus keeping both initial and running costs down. It features a pile-type (pile foundation) structure, which minimizes changes to the riverbed ground and shortens the construction period. It is expected to be installed in sites requiring urgent safety measures with a short construction period. Additionally, it can be installed regardless of the foundation conditions or land acquisition in the upstream area since it does not use anchors in the upstream section. - Suitable for debris flow and driftwood measures in non-flowing streams (small-scale streams) - Pile-type (pile foundation) structure that achieves a small installation area and shortened construction period - Reduced initial installation costs, making it an economically advantageous measure - Capable of capturing repeated debris flows and driftwood - Adopts high-strength supports with excellent "ductility" function Ministry of Land, Infrastructure, Transport and Tourism New Technology Information System (NETIS) Registration Number: KT-210079-A Construction Technology Review Certificate: No. 1901 (General Incorporated Foundation, Sediment Disaster Prevention and Landslide Technology Center) *For more details, please download the PDF or feel free to contact us.

Capture of small stones, gravel, and driftwood slipping through a steel slit dam.

The "Korekkiri Screen" is a product that captures small stones, gravel, and driftwood that slip through the gaps between the steel pipes of a sluice gate by securing wire ropes in a screen-like configuration on the concrete sections of both banks of a transparent steel slit dam. The installation spacing of the wire ropes can be adjusted according to the designed gravel diameter. By fine-tuning the spacing to the optimal distance for the site, it reliably captures flowing gravel. ■ Measures against small to medium-sized stones and driftwood ■ Enhances the capturing function of steel slit sluice gates ■ Simple structure with wire ropes installed in a screen-like manner *For more details, please download the PDF or feel free to contact us.

Protective fences applicable for rockfalls, avalanches, and landslide debris measures.

The "SPARC Fence" is a slope-installed rockfall protection fence primarily designed to protect roads and houses from falling rocks. It can withstand rockfall energy of up to 318 kJ. Due to its structure, which does not use a damping device, it can also accommodate static loads from snow and collapsed earth. It is effective for rockfall measures in snowy regions and avalanche prevention on slopes with rockfall hazards. Additionally, it can be utilized as a temporary protective fence at construction sites for cut slopes and on weathered slopes. ■ Applicable for rockfall, avalanches, and collapsed earth ■ Supports rockfall energy up to 318 kJ ■ No damping device, resulting in low maintenance frequency ■ Minimal net deformation during rockfall capture Ministry of Land, Infrastructure, Transport and Tourism New Technology Information System (NETIS) Registration Number: HR-130008-A *Registration period has ended *For more details, please download the PDF or feel free to contact us.

Vertical erosion sediment control fence with excellent sediment capture performance and maintenance management.

The "Slope Guard Fence Type LE" is a vertical type of collapse debris protection fence designed to catch collapsing soil near roads or behind houses. It prevents the outflow of soil using panel-type wire nets and wire mesh installed between the support posts. Due to its pile foundation structure, where the posts are directly embedded into the ground, it can be installed in various locations, including sites with limited space or on slopes. By adjusting the height of the fence, it is possible to secure pocket capacity for soil accumulation, minimizing alterations to the slope. It can withstand rockfall energy up to 318 kJ, making it suitable for a wide range of applications. ■ Measures against collapsing soil near roads and behind houses ■ Vertical protection fence with pile foundation structure ■ Structure considering soil impact force and accumulated soil pressure Ministry of Land, Infrastructure, Transport and Tourism New Technology Information Provision System (NETIS) Registration Number: HR-100008-VR *Registration period has ended "Evaluation Promotion Technology (New Technology Utilization System Study Meeting (Ministry of Land, Infrastructure, Transport and Tourism))" *For more details, please download the PDF or feel free to contact us.

It can accommodate falling rock energy of up to 1200 kJ and can be used in conjunction with measures against collapsing earth and avalanches.

Since it is a pile foundation structure that directly embeds the pillars into the ground, it can be constructed in various locations, including sites with limited installation space and on slopes. The pillars, which have high strength and excellent toughness, have been confirmed through full-scale experiments to be reusable even after capturing falling rocks. Compared to other methods, the need for component replacement after a disaster is minimized, making maintenance easy and reducing costs. ■ Two types available for rockfall energy resistance: 500 kJ and 1200 kJ ■ Vertical protective fence with pile foundation structure ■ Can be combined with measures against collapsing soil and avalanches ■ Easy maintenance after rockfall capture Ministry of Land, Infrastructure, Transport and Tourism New Technology Information System (NETIS) Registration Number: HR-100008-VR *Registration period has ended "Evaluation Promotion Technology (New Technology Utilization System Study Meeting (Ministry of Land, Infrastructure, Transport and Tourism))" *For more details, please download the PDF or feel free to contact us.
