Gabion is a flexible protective structure used in hydraulic engineering.Composed of double twisted hexagonal metal mesh woven from low-carbon steel wire, filled with stone blocks, mainly used for erosion control, riverbank protection, and ecological restoration.

Core Features and Structure

The core advantages of the solid berm cage lie in its‌flexible design‌and‌ecological compatibility‌:

1. Material & Process: Low-carbon steel wire with tensile strength of 350-550N/mm² is used, coated with hot-dipped zinc, Galfan or plasticized treatment for durability. The mesh size is typically 60×80mm to 120×150mm, with a mesh box height ranging from 0.15m to 1.5m, and customization is supported.
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 as well as vegetation growth.

Application Scenarios and Advantages

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

1. Main Application:

River and Embankment Protection: Effectively resists erosion from water flow, with a scour resistance up to 6m/s, suitable for mountainous rapids 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 collapsible transportation and rapid on-site assembly, allowing direct use of local stone to fill, reducing costs and project duration.‌

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

Specs and Buying Guide

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

• ‌Common 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 design.‌
• Surface Treatment: Hot-dip galvanized for general environments; Galfan coating or plastic coating for enhanced corrosion resistance, suitable for highly corrosive waters.
