  • Erosion control panels
    Patent number: 6843616
    Abstract: An erosion control device is a panel formed of spaced horizontal and spaced vertical rods joined together to create a frame upon which is mounted a sheet of silt fencing material. A plurality of such panels may be rotatably joined together to form different configurations of erosion control fencing. The panels are reusable and the silt fencing material may be replaced thereon. The silt fencing material may be used to form a pocket for sand, thus forming a sandbag at the base of the panel for controlling water flow. The panel may have affixed thereto at the base a narrow metallic strip for cutting into the ground as the panel is forced downward thereon.
