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.
