When it comes to gabion walls, there are certain standards that need to be followed to ensure their stability and effectiveness. The most common design for gabion walls is a pyramid shape, and for every 1m increase in wall height, the bottom row basket depth should be increased by half a meter. For a 2m high wall, the bottom row should be 1.5m deep and the top row should be 1m deep. Additionally, using a wire thickness of 3mm for both rows is still considered standard practice.
What Are the Standards for Gabion Walls?
The dimensions of the gabion baskets also follow specific standards. The length and width of the baskets are typically standardized to be 2 meters by 1 meter. The height of the baskets can vary depending on the required wall height, but a common standard is 1 meter. The baskets are usually filled with a combination of stones and soil, ensuring proper compaction to maintain stability.
In terms of durability, the gabion wall should meet certain strength requirements. The wire used for the baskets should have a tensile strength of at least 350 Newtons per square millimeter. This ensures that the baskets can withstand the pressure exerted by the filling materials and maintain their structural integrity.
Proper drainage is also an important factor in the design of gabion walls. The baskets should be constructed with a non-woven geotextile liner, which allows water to pass through while preventing the washout of fine soil particles. Adequate drainage avoids the build-up of hydrostatic pressure behind the wall, which could lead to instability.
Adhering to these standards is crucial to ensure the long-term effectiveness and safety of gabion wall structures.
