Officine Maccaferri Spa: Rockfall protection & Natural hazard mitigation
- 1. Date: February 2017 ROCKFALLPROTECTION & NATURAL HAZARD MITIGATION
- 2. Rockfall protection and mitigation arekey elements in the security and safety of people and our infrastructure: roads, rail, mines and buildings.
- 3. We can helpto mitigate and reduce natural hazards.
- 4. Because nature isnot consistent….. …no single solution is right for every problem.
- 5. We work withour clients to engineer a solution. We select from our broad range of systems, often using them in combination.
- 6. Simple Drapery Mesh SurfaceStrengthening and Support Mesh Dynamic Rockfall Barriers Our solutions: Our solutions:
- 7. Debris Flow Barriers RockfallEmbankments Snow Fences and Avalanche Protection Soil Nailing
- 8. Where are thesesolutions used?
- 9. Simple Drapery Mesh •Double-twist woven steel mesh • Heavy zinc-aluminium galvanised with polymer coating for long design life • Easy to unroll on rock-face • DT mesh construction will not unravel and maintains 85% of its strength even when one wire is broken Simple drapery mesh
- 10. • High strength,high stiffness steel mesh geocomposite • DT Mesh with integral high tensile steel cables • Tensile strength up to 180 kN/m • Punch resistance up to 150 kN • Zn-Al heavy galvanised with optional polymer coating Steelgrid HR Surface Strengthening & Support Mesh
- 11. • High tensilesteel wire cable panel • Highest stiffness mesh in range • Tensile strength up to 300 kN/m • Punch resistance up to 460 kN • Patented ‘double knot’ connection HEA Panels Surface Strengthening & Support Mesh
- 12. • Range offences with energy absorption capacities from 100kj to 8,600kJ • Fences certified in accordance with International standards (e.g. ETAG 027) • Lowest deflection under impact • Class A • Patented compression brakes Dynamic Rockfall Barriers
- 13. Soil Nailing • Reinforcesthe slope by the insertion of soil nails • Connects the unstable surficial layers with the stable deep slope • Variety of surface stabilising meshes • This technique provides stability while vegetation becomes established Soil Nailing
- 14. • Customised tosuit the anticipated debris material and the expected flow volume • Barrier progressively deforms with the compression brakes and systems absorbing the energy • Offers strength and performance with good aesthetics Debris Flow Barriers
- 15. • Built usingreinforced soil; can often use locally available site-won materials • A variety of face finishes are available • Scalable to accommodate extreme rockfall impacts (20,000kJ +) and divert debris flow • Can sustain multiple impacts and rockfall events without the need for repair Rockfall Embankments
- 16. • Stabilises thelayer of snow at the potential avalanche initiation zone • Flexible system: reduces loads imposed on foundations = more efficient • SFISAR Approval for our snow fences up to 4.5 m high Snow Fences & Avalanche Protection
