Report on Participation in the Defense Facilities Society "Military Engineer Tech Fair"

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.

A reinforced soil wall with a proven track record of absorbing large-scale impacts using reinforced soil.

The "Geo-Lock Wall" is a reinforced earth wall designed to absorb falling rocks, landslides, and collapsing soil, primarily along roadsides and behind residential houses. It can withstand rockfall energy of up to 5500 kJ and is utilized for a wide range of rockfall countermeasures from small to large scale. It primarily uses soil and geosynthetics as materials. Due to the unique flexible structure of soil structures, it efficiently absorbs impacts and can handle large-scale impact energy. Because it is a soil structure, it can be installed in various terrains, including sites with limited installation space, sites with vertical gradients, and sites with valley topography. Additionally, it does not transmit impact forces to the supporting ground, so in most cases, ground improvement treatments are not necessary. ■ Rockfall, landslide, and collapsing soil countermeasures using reinforced earth ■ Capable of withstanding rockfall energy up to 5500 kJ ■ Available in three types according to the scale of rockfall ■ Over 540 adoption records nationwide Ministry of Land, Infrastructure, Transport and Tourism New Technology Information System (NETIS) Registration Number: HR-990009-V *Registration period has ended NETIS Fiscal Year 2016 Semi-Recommendation Technology *For more details, please download the PDF or feel free to contact us.

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.

An energy-absorbing rockfall protection fence boasting overwhelming adoption results!

The "ARC Fence" is a rockfall protection fence primarily installed on slopes to protect roads and homes from falling rocks. It offers six types corresponding to rockfall energies of 61 kJ, 106 kJ, 223 kJ, 316 kJ, 504 kJ, and 1,002 kJ, and all construction from drilling to fence installation can be done manually, making it economically efficient for rockfall measures on slopes. Additionally, by adjusting the spacing between the posts, it can be arranged in various terrains, and its lightweight and simple structure allows for easy installation. ■ Supports rockfall energy up to 1,002 kJ ■ Applicable to various terrains ■ Simple structure with excellent workability and cost-effectiveness ■ Extensive adoption track record nationwide Ministry of Land, Infrastructure, Transport and Tourism New Technology Information System (NETIS) Registration Number: CB-020004-VE *Publication ended NETIS Evaluation Promotion Technology for Fiscal Year 2017 *For more details, please download the PDF or feel free to contact us.

High energy absorption type rockfall protection fence with small net deformation during rockfall capture.

The "Macro Fence" is a rockfall protection fence installed on slopes to protect roads and homes from rockfall disasters. It can withstand rockfall energy of up to 5000 kJ, making it effective for large-scale rockfall countermeasures. Due to the small deformation of the net during rockfall capture, it can be placed relatively close to the objects being protected. The deformation amounts of the nets for each type have been confirmed through experiments. By allowing for a configuration that is relatively close to the protected objects, the area required for land acquisition can be minimized, leading to expected cost reductions. ■ Slope-installed protection fence ■ Supports rockfall energy up to 5000 kJ ■ Effective for large-scale rockfall countermeasures ■ Available in five types according to the scale of rockfall Ministry of Land, Infrastructure, Transport and Tourism New Technology Information System (NETIS) Registration Number: HR-090007-A *Registration period has ended *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.
