For these projects, it has become increasingly popular to use plant-compatible components or structures in recent years to meet the needs of slope protection while repairing and rebuilding the riverbank or slope ecology. Grid gabions filled with stones are commonly used components. They use metal wires to make boxes, fill the boxes with stones, and use the boxes to build retaining walls or protective surfaces for slope protection or bank protection.
