Gabion

Gabions can be employed in a variety of ways to stabilize soil conditions around bridges, bridge piers and bridge abutment slopes. Generally the angle of the slope to be protected shall determine what structure type is best suited for each application. Slopes with an angle of 1on1 or steeper require standard Gabion retaining wall protection. Slopes with an angle of 1 on 1.5 or less may use a gabion or reno mattress 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:

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.
