Gabion baskets are flexible protective structures used in hydraulic engineering.Consisting of a double twisted hexagonal metal mesh box woven from low-carbon steel wire, filled with stones, it is mainly used for riverbank reinforcement against erosion, riverbank protection, and ecological restoration.
Core Features and Structure
The core advantages of the Fixed Bank Basket lie in itsflexible designandecological compatibility:
- Material & Process: Utilizes low-carbon steel wire with tensile strength of 350-550N/mm², heat-dipped galvanized, Galfan coated, or plastic coated for durability. Mesh sizes typically range from 60x80mm to 120x150mm, with mesh box heights from 0.15m to 1.5m, and customization is supported.
- Structural Features: The double twisted hexagonal weave provides the cage with strong deformation adaptability, able to cushion water flow impact; after filling with stones, it forms a porous structure with excellent permeability, preventing static water pressure damage. Additionally, the stone gaps facilitate soil and water exchange and vegetation growth.
Application Scenarios and Advantages
Coastal gabions are widely used in hydraulic engineering, balancing protection and ecological benefits.
1. Main Application:
Channel and Embankment Protection: Effectively resists erosion from water flow, with a scour-resistant velocity of up to 6m/s, suitable for mountainous rapid streams or urban flood control projects.
Ecological Restoration: The porous structure promotes the rooting of aquatic plants and the habitat for organisms, achieving the dual effect of "engineering protection + ecological restoration," as seen in the Hangzhou Landscape River case.
2. Comprehensive Advantages:
Easy Construction: Supports folding for transport and quick assembly on-site. Directly utilizes local stone for filling, reducing costs and project duration.
Economic: Lower cost than concrete structures, with low foundation treatment requirements, especially suitable for poor soil areas.
Specs and Selection Guide
The specifications of the gabion baskets should be selected according to the engineering requirements.
- Common Specifications: Wire diameter 2-4mm, edge wire diameter 0.5-1.0mm larger than the mesh wire; mesh box sizes such as 2m x 1m x 1m or customized design.
- Surface Treatment: Hot-dip galvanized for general environments; galvanized Galfan or plastic coated for enhanced corrosion resistance, suitable for highly corrosive water bodies.
