Product Details

Galvanized Wire Mesh Gabion Rock Cage

Product Description

Galvanized rock cage is a hexagonal wire mesh box,container or basket which is used to prevent soil erosion and retain soil particles filled with rock.It is normally used together with geotextiles to reduce water velocities and re-capture river bed sediment in streams.

Galvanized rock cage called gabion basket or gabion box is widely used in river courses where soil erosion is a problem over a large flat or sloped area needing protection against soil loss or scour.They are used mostly in the civil engineering industry especially in the construction of roadway drainage structures,however recently due to their environmental benefits are being used in many various applications and industries.

Features

Galvanized rock cage have been widely used in many industries because of following features.

High strength – un-weathered rocks used within the gabion provide high compressive strength.
Enhanced flexibility – woven steel wire mesh is used for the baskets, allowing movement over expansive soils without failure.
Labor intensive – gabions use a lot of manpower, with little use of machinery required. Unskilled labor from local communities can be used and trained in a short time period.
Low environmental impact – vegetation and plants/trees can be incorporated in the gabion system to cover the gabion or mattress protection in a short time.
High porosity – gabions unlike concrete do not require weep-holes for water pressure release behind the retaining walls, they have a 35% pore space volume, allowing free movement of water through the walls, and soil fines movement are blocked with a geotextile filter fabric.
Bomb and earthquake proof – gabion structures can provide protection for; bomb shelters and earthquakes, especially when filled with rock and soil due to their high flexibly/strength characteristics.
Mattress linings – offer vegetation growth and the benefit of microorganisms within the structure to provide food for insects, fish and animals in river situations, unlike the environment created using a solid or segmented concrete lining with little environmental benefits.
Simple – Local labor is used to erect baskets, and can be trained up in a short time period on site.
In time – vegetative root growth will enhance the strength of the structure by binding the rocks together and stabilizing it with soil infill in streams.
Economical – suitable rock infill and the use of local labor can be sourced from quarries and communities near the site.

Applications

Galvanized rock cage has a wide range of applications and new ones are continually being found. We have listed below the most common applications to date, manufactured using either woven double twisted or welded square mesh.
