Gabion baskets are flexible protective structures used in hydraulic engineering.Composed of a double twisted hexagonal metal mesh woven from low-carbon steel wire, filled with stones, mainly used for riverbank reinforcement against erosion, riverbank protection, and ecological restoration.
Core Features and Structure
The core advantages of the solid mooring baskets lie in their flexible design and ecological compatibility:
- Material and Process: Utilizing low-carbon steel wire with tensile strength of 350-550N/mm², heat galvanized, Galfan coated, or plastic coated for durability assurance; mesh size typically ranges from 60×80mm to 120×150mm, mesh box height from 0.15m to 1.5m, with customization available.
- Structural Features: The double twisted hexagonal weave design endows the net box with strong deformation adaptability, capable of buffering water flow impact. After filling with stone, it forms a porous structure with good permeability, preventing static water pressure damage. Additionally, the gaps between the stones facilitate soil and water exchange and vegetation growth.
Application Scenarios and Advantages
Fixed bank baskets are widely used in hydraulic engineering, balancing protection and ecological benefits.
1. Main Application:
River and Embankment Protection: Effectively prevents erosion of riverbanks by water flow, with erosion-resistant velocity up to 6m/s, suitable for mountainous rapid rivers or urban flood prevention projects.
Ecological Restoration: The porous structure promotes the root growth of aquatic plants and the habitat for organisms, achieving dual effects of "engineering protection + ecological restoration," as demonstrated in the Hangzhou landscape river case.
2. Comprehensive Advantages:
Easy Installation: Supports collapsible transportation and quick on-site assembly. Allows for direct use of local stone to fill, reducing costs and project duration.
Economic: Lower cost than concrete structures, with low foundation treatment requirements, particularly suitable for poor soil areas.
Specs & Buying Guide
The specifications of the riprap baskets should be selected according to the engineering requirements.
- Standard Specifications: Wire diameter 2-4mm, edge wire diameter 0.5-1.0mm larger than the wire diameter; mesh box sizes such as 2m x 1m x 1m or customized designs.
- Surface Treatment: Hot-dip galvanized for general environments; Galfan or plastic coating for enhanced corrosion resistance, suitable for highly corrosive water bodies.
