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.

Detailed information
-
"Response to falling rocks, avalanches, and collapsing soil with multi-functionality" Due to its structure that does not use a damping device, it can also accommodate static loads from snow accumulation and collapsing soil. The SPARC60 can handle snow depths of up to 3.5 meters, while the SPARC100/300 can handle snow depths of up to 3.0 meters. Furthermore, it can also be utilized as a temporary protective fence for falling rocks and soil accumulation at construction sites on weathered slopes and cut slopes.

Repeatedly capturing falling rocks reduces the frequency of maintenance management. Due to the minimal deformation of components and reduction in fence height after capturing falling rocks, it is possible to repeatedly capture the maximum scale of falling rocks anticipated in the design. It excels in maintainability, achieving a reduction in the frequency and effort required for maintenance after rock capture, as well as a reduction in costs. Real-world experiments have confirmed that the necessary fence height can be maintained even after a heavy weight impact.
-
"Easy installation with a lightweight and simple structure" Due to its simple structure and lightweight components, it can be safely and easily installed on slopes. It can be transported and constructed manually, allowing for short construction periods and low costs.
