Gabions offer excellent protection as soil stabilizers around bridges, bridge piers and abutment slopes. Gabion is a low profile gabion made of galvanized double-twisted wire mesh and filled with rocks. This kind gabion can be supplied in various length, widths and height.
The most common sizes are : 12’x 6′, 9’x6′ and 6’x6′ with depths of 6″, 9″ or 12″. We also supply gabion mesh in lenghts up to 100′ long and shipped as rolls Generally, the degree of the slope to be protected shall determine what structure type is best suited for a specific application.
Slopes with an angle of 1:1 or steeper usually require standard gabion retaining wall protection. Slopes with an angle of 1:1.5 or less may use a combination of gabion baskets and/or mattresses for slope protection.
Reno Mattress is a double twisted hexagonal woven galvanized steel wire mesh compartmented basket with a rectangular mattress shape. The compartment or cells of the reno mattress are of equal size and dimension and are formed by internal diaphragms being placed within the basket providing even distribution of the stone fill throughout the mattress even after structural movement. Even distribution of the stone fill ensures that the reno mattress maintains intimate contact with the foundation soil.
Main Characteristics of Bridge Protection System Composed of Gabion Retaining Wall:
1. Good adaptablity:adapting to the deformation of the groundwork.
2. High flexibility:not likely to be broken,bearing a large range of deformation without collapsing
3. With both penetratabiliyt and non-penetratability, damage caused by fluid static power is prevented.
4. Anticorrosive and washing-away-resisting, high resistance to natural damage,bad climate,quake and impact.
