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.

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.

Preventing glide on snow-covered slopes: Simple and easy-to-install steel avalanche prevention stakes.

"Tri-Pile" is an avalanche prevention stake installed on slopes to suppress snow glide. It is effective in preventing the occurrence of full-depth avalanches. The components are lightweight and have a very simple structure, making them easy to install. The heaviest component weighs about 15 to 20 kg, allowing for manual transportation and installation. Since a small-scale self-drilling anchor is used for the foundation, there is no need for large heavy machinery. This is expected to shorten construction time and reduce costs. ■ Slope-mounted avalanche prevention stake ■ Suppression of snow glide ■ Effective against full-depth avalanches Ministry of Land, Infrastructure, Transport and Tourism New Technology Information System (NETIS) Registration Number: CG-120027-A *Registration period has ended *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.
