Passive protective net gabion mesh is a type of mesh structure material used for slope protection and other engineering projects. Below are its detailed specifications:

Material

·Wire Material: Common materials include high-quality low-carbon steel wire and stainless steel wire. Among these, low-carbon steel wire has relatively lower costs and can achieve good strength and corrosion resistance after appropriate treatment; stainless steel wire offers higher corrosion resistance and oxidation resistance, making it suitable for environments with high weather resistance requirements.

·Surface Treatment: To enhance the corrosion resistance of the gabion mesh, the wire is typically subjected to surface treatments such as hot-dip galvanizing, electro-galvanizing, plastic coating (PVC, PE coating), dip coating, or spray coating. Hot-dip galvanized gabion mesh exhibits strong anti-corrosion capabilities and a longer service life.

Weaving Process

Gabion mesh is woven using a gabion mesh machine. The process involves first processing the metal wire into flat spiral-shaped semi-finished products, which are then interwoven in a spiral manner to form a structure with uniform mesh openings and a flat surface. This weaving method gives the gabion mesh excellent flexibility and impact resistance.

Specifications

·Mesh Size: Common specifications include 2cm×2cm, 3cm×3cm, 4cm×4cm, etc. Custom mesh sizes are also available based on customer requirements.

·Wire Diameter: The wire diameter generally ranges from 1mm to 7mm. Different wire diameters correspond to different strength requirements, allowing for the selection of an appropriate wire diameter based on actual protection needs.

·Mesh Dimensions: The width can typically range from 0.5 meters to 6 meters, and the length from 4 meters to 50 meters. Custom dimensions are also supported.

Features

·Excellent Flexibility: It can adapt to changes in slope terrain. Even with minor deformations of the slope, it maintains its protective function and is less likely to be damaged by slight displacements.

·High Strength and Impact Resistance: Woven from high-quality metal wire, it offers high strength and can withstand impact loads such as falling rocks. It absorbs and disperses impact forces through its own deformation.

·Good Water Permeability: The mesh structure allows rainwater to penetrate the slope soil easily, preventing soil erosion caused by excessive surface runoff. It also reduces pore water pressure and enhances slope stability.

·Easy Installation: Its relatively light weight and simple installation process allow for on-site weaving or pre-fabrication and installation, improving construction efficiency and reducing costs.

Application Scenarios

It is primarily used for slope protection along highways and railways, slope protection in mining operations, and in mountainous areas with buffer zones near construction facilities. It effectively blocks rockfalls, flying rocks, avalanches, etc., protecting nearby roads, buildings, and personnel.

Installation Method

Generally, fixed piles are first driven into the edges of the installation site. The depth and stability of these piles must ensure that the gabion mesh remains secure and does not shift after installation. The gabion mesh is then unfolded and laid along the positions of the fixed piles, ensuring the mesh surface is flat. Finally, the gabion mesh is secured to the fixed piles using wire or specialized connectors.
