Gabion cages are widely used in marine breakwaters to resist wave erosion and storm surges. Their flexibility allows them to adapt to seabed movements while maintaining structural integrity.
Material: High镀锌 (galvanized) or PVC-coated steel wires (e.g., zinc-aluminum alloy wires with 5% Al content) to withstand saltwater corrosion
Submarine Pipeline Protection
Pre-filled gabion boxes are deployed around underwater pipelines to shield against anchor strikes and seabed abrasion.
Installation: Assembled on barges and submerged using cranes, with final positioning guided by divers
Marine Structure Foundations
Gabion mattresses (reinforced earth pads) provide stable foundations for offshore platforms and tidal energy devices.
Standard Compliance: Meet EN10223-3 standards for wire diameter (2.0–4.0 mm) and tensile strength (>350 MPa)
Erosion Control in Estuaries
Modular gabion systems prevent bank collapse in brackish water environments. Their permeable design allows natural sediment deposition and vegetation growth
Floating Breakwaters
Hollow gabion structures filled with buoyant materials (e.g., foam) are used to dissipate wave energy in harbors.
Advantage: Lower maintenance costs compared to concrete structures
Key Technical Features
Corrosion Resistance: Zinc-aluminum alloy coatings (Galfan) extend service life to >50 years in marine conditions
Permeability: Allows water flow through gaps, reducing hydrostatic pressure and preventing undermining
Modular Design: Prefabricated units (e.g., 2m×1m×1m cages) enable rapid deployment in harsh marine environments
Case Studies
Cross-Sea Pipeline Projects: Gabion cages protected 10 km of underwater oil pipelines in the South China Sea, with zero failure reports after 10 years
Reef Restoration: Gabion frameworks in the Mediterranean support artificial reefs, enhancing marine biodiversity
