Gabion Retaining Wall
Configuration
Gabion retaining walls can be designed in two configurations: smooth front and step front configurations. In both configurations, a batter angle is incorporated to enhance safety and prevent the boxes from sliding. Research and experimental findings have confirmed that the batter angle contributes to the stability of the retaining walls.
When using gabion walls with a smooth front face, it's recommended to place the wall at a 6 to 10-degree batter angle, suitable for wall heights up to 5 meters. On the other hand, walls with a step front face should be positioned at a 4 to 6-degree batter angle toward the retained slope. This necessitates grading and compacting the founding soils to accommodate the specified wall batter.
Dimensions
For stable gabion retaining walls, it's crucial to proportion the base width relative to the wall height. A general rule of thumb is to maintain a base width of 2/3 of the wall height, ensuring long-term structural stability and reducing the risk of failure. Gabion gravity walls are typically constructed up to 9 meters, but optimal performance is achieved at heights of 5 meters or less. For taller walls, MSE slope protection is recommended.
Gabion walls are built using individual boxes, with each box not exceeding 1 meter in height. The total number of boxes needed is determined by the overall wall height—for example, a 3-meter wall would require 3 boxes. The width of each box is based on the base width calculation, ensuring proper support.
For retaining gravity walls with a stepped front face, a setback of at least 0.5 meters is recommended for each box after the first meter of height. This setback helps maintain structural integrity and provides a more secure configuration.
Key Factors for Long-Lasting Gabion Retaining Walls
Foundation below Grade
Gabion retaining walls aren't just for above-ground use; they can also be a lifesaver below grade, protecting against erosion caused by water currents and waves. A good rule of thumb is to bury them about twice as deep as the expected erosion depth. This buried layer of Gabion acts as a sturdy barrier at the base of the wall, helping to prevent soil from being washed away.
Installing this underground layer requires minimal excavation and is typically placed directly on the ground. To ensure durability and longevity, a filter fabric is often used to prevent soil erosion. And if the base needs to be placed underwater, no worries! It can be prefabricated on a barge and carefully lowered into place.
For added protection in underwater environments, we also offer the option of applying a PVC finish coating to the gabion boxes or ren mattress upon request. It's all about keeping your retaining wall strong and resilient, no matter the conditions it faces.
Shape control
Both welded mesh gabion walls and double twisted mesh gabion walls have their unique advantages and disadvantages, particularly concerning strength and durability in retaining wall applications.
Welded mesh gabion walls offer superior strength due to their construction. Each wire, typically 4 mm in diameter, is welded at every junction, providing a rigid structure capable of bearing significant stress. This rigidity helps prevent the wall from changing shape due to bending or external pressure.
On the other hand, double twisted mesh gabion walls offer flexibility, making them well-suited for rough terrains or areas prone to movement. The double twisted mesh design allows the wall to bend without fracturing, providing resilience in situations such as scour occurrences.
Filter Fabric and Back fill
There are various options for backfilling gabion walls, but it's absolutely crucial to do it properly. If the backfill soil isn't packed down correctly, the wall could sink, shift sideways, or end up weaker than expected. Proper compaction of the backfill is essential, following specific guidelines to ensure it's dense and stable.
In any gabion application, the filter fabric plays a critical role in preventing soil erosion through the voids in the rocks filled inside the gabion boxes. Choosing the right filter fabric is essential, as the wrong selection can result in the loss of retained soil and a change in the elevation behind the wall. The choice of filter fabric depends on the type of backfill soil used for the retaining wall.
