Debris Flow Barriers
Our DF Series of debris flow barriers have been developed to contain soil/water flows (debris flows) or shallow landslides on slopes, channels and chutes.
The DF Barriers are customised to suit the dimensions of the project, the anticipated debris material and the expected volume of the flow. Upon impact by the debris flow, the DF Barrier progressively deforms with the compression brakes and systems absorbing the energy. The hydrostatic pressure within the flow rapidly dissipates once the debris flow has been arrested, leaving the volume of debris within the barrier.
Maccaferri DF Barriers offer strength and performance without the aesthetic intrusion of other debris flow systems.
Attenuator / Hybrid Barriers
Based heavily on our dynamic rockfall barriers, our Hybrid and Attenuator Systems combine the energy absorption capabilities of a dynamic rockfall barrier with the reduced-maintenance advantages of drapery mesh. Rather than being secured to a lower support cable, the fence mesh is longer and drapes down the slope. Therefore, a falling rock is not captured and stopped as with a traditional rockfall barrier, but following impact with the barrier, the rock continues down the slope beneath the mesh draped down the slope face. The rock is progressively slowed beneath the mesh.
Hybrid and Attenuator Systems are used on slopes where there is available ‘run-out’ space beneath the barrier in which the rocks can ultimately stop or be collected harmlessly.
Our Attenuator and Hybrid barriers are supplied in kit form; all components (except ground anchors) are provided in the kit, including panel mesh, anchor posts, footing plates, brakes, cables, and clips.
