Gabion is a flexible protective structure used in hydraulic engineering.Consisting of a double twisted hexagonal metal wire mesh box woven from low-carbon steel wire, filled with stones, mainly used for riverbank stabilization, slope protection, and ecological restoration.

Core Features and Structure

The core strengths of the gabion cage lie in its‌flexible design‌and‌ecological compatibility‌:

1. ‌Material and Process: Utilizing low-carbon steel wire with tensile strength of 350-550N/mm², coated with hot-dipped galvanized, Galfan, or plastic coating to ensure durability; mesh size typically ranges from 60×80mm to 120×150mm, mesh box height from 0.15m to 1.5m, with customization available.‌
2. Structure Features: The double twisted hexagonal weaving method provides the cage with strong deformation adaptability, capable of buffering water flow impact. After filling with stone blocks, 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

The gabion baskets are widely used in hydraulic engineering, offering both protection and ecological benefits.

1. Main Application:

‌ River and Embankment Protection: Effectively resists erosion by water flow, with a resistance to erosion up to 6m/s, suitable for mountainous rapid rivers or urban flood prevention projects.‌

Ecological Restoration: Multi-porous structures enhance the rooting of aquatic plants and the habitat for organisms, achieving the dual effect of "engineering protection + ecological restoration," as demonstrated in the Hangzhou Landscape River project.

2. Comprehensive Advantages:

Ease of Construction: Supports folding for transport and quick assembly on-site. Directly utilizes local stone for filling, reducing costs and time.

‌Economic: Lower cost than concrete structures, with reduced foundation treatment requirements, particularly suitable for poor soil areas.‌

Specs and Selection Guide

The specifications of the riprap baskets should be selected based on engineering requirements.

• ‌Standard Specifications: Wire diameter 2-4mm, edge wire diameter 0.5-1.0mm thicker than the mesh wire; 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.
