Vertical rockfall protection fence "Loop Fence"

Vertical rockfall protection fence "Loop Fence"

A vertical rockfall protection fence with a simple and rational structure to prevent falling rocks onto the road.

The "Loop Fence" is a vertical rockfall protection fence primarily installed along roads to prevent rockfall damage. It can withstand rockfall energy of up to 1506 kJ, making it effective for relatively large-scale rockfall countermeasures. By wrapping wire ropes in a loop between the posts, it reduces the deformation during rockfall capture. Its minimal protrusion towards the road allows for installation close to the roadside. ■ Catches rockfalls on roadsides and slopes ■ Supports rockfall energy up to 1506 kJ ■ Effective for large-scale rockfall countermeasures Ministry of Land, Infrastructure, Transport and Tourism New Technology Information System (NETIS) Registration Number: SK-020001-V *For more details, please download the PDF or feel free to contact us.

Multi-functional rockfall protection fence 'SPARC Fence'

Multi-functional rockfall protection fence 'SPARC Fence'

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.

High-energy absorption rockfall protection fence "Macro Fence"

High-energy absorption rockfall protection fence "Macro Fence"

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.

Extended structure type energy-absorbing rockfall protection fence "Bist Fence"

Extended structure type energy-absorbing rockfall protection fence "Bist Fence"

The development of a new energy absorption mechanism and high-strength wire mesh has significantly improved tear resistance and toughness!

The "Bist Fence" is a cantilever structure type rockfall protection fence with a rockfall energy capacity of 300 kJ. By combining a new post structure, high-strength wire woven in a diamond shape, and an EA device (impact mitigation device), it efficiently absorbs rockfall energy and reduces the burden on components. Since concrete pouring is not required, it can shorten construction time and is also suitable as an emergency temporary protection measure for disaster recovery. 【Features】 ■ High impact absorption capacity ■ Can be constructed in a short time ■ Easy to install and maintain ■ Single-span installation is possible ■ Rockfall energy capacity: 300 kJ ■ NETIS registration number: HK-180009-A *For more details, please refer to the PDF materials or feel free to contact us.
