A dense fill material is loaded onto the bottom panel prior to closure providing mass for strength and stability against impacts. The flat panels may be hingeably interconnected and foldable to optionally form a compact stackable configuration for storage and transport. A multiplicity of such modules may be positioned and connected to form a continuous massive wall for such uses as reducing damaging wave action, preventing beach erosion, directing water in flood areas, and providing highway barriers for guidance and safety.Field of SearchBANK, SHORE, OR BED PROTECTIONRevetment Revetment laying Continuous concrete or concrete filled bag Wave or flow dissipation Artificial water barrier (e.g., dam, levee, etc.) Hollow or buttressed With ballast compartment or cavity Connectable sections In situ construction Retaining wall Concrete Cast in situ Ground stabilization or reinforcement | |
