Flexible ring net barriers for retaining debris flow and mudslides

• enormous reduction in construction time
• cost-savings of 30 to 50 % compared to concrete structures
• environment-friendly solutions, adapting visually into the landscape
• tested in field trials with the Swiss Federal Research Institute for Forest, Snow and Landscape WSL 
• single-level barriers for events of up to 1’000 m³, multilevel barriers for events of several 1’000 m³

Components:

• Thanks to the elastoplastic behavior, ROCCO^® ring nets themselves absorb energy, thereby reducing stress on the anchors
• Brake rings in the support and border ropes are activated with major events, dissipating energies from the ring net without damaging the ropes
• Thick-section angle steel protect the top support ropes from the abrasive effect of rubble and boulders
• Spiral rope anchors or self-drilling anchor with Geobrugg FLEX head 
• For UX barriers we use posts type HEB that are mounted on a baseplate via a link
