Abstract
Man-made boulders anchored to a grade beam to prevent erosion of a bulkhead. The boulders are fabricated using woven bags filled with concrete and located on the water side of the bulkhead. An anchor bolt is embedded in the top surface of the boulder concrete. A concrete grade beam equipped with anchor bolts is located on the land side of the bulkhead. Cables are threaded between the anchor bolts of the concrete boulders and the anchor bolts of the grade beam. The weight of the concrete boulders plus the tensioned cables provide a structure that resists movement and protects the bulkhead from deterioration due to wave action. If upgrade soil protection is needed, rock-filled gabion cages can be installed over the grade beam.
Claims20
Apparatus for preventing erosion of soil by water, said apparatus comprising:
- a container having sidewalls, a bottom and an open top;
- concrete filling said container;
- said concrete-filled container located adjacent to an area to be protected from erosion;
- an anchor mechanism at least partially embedded in said concrete, said anchor mechanism anchored to maintain said concrete-filled container adjacent to said area to be protected from erosion;
- and
- at least one cable extended from the anchor mechanism of said concrete-filled container to a remote anchor location so that said at least one cable overlies the area to be protected from erosion.
Apparatus for preventing erosion of soil by water, said apparatus comprising:
- a plurality of concrete boulders, each concrete boulder having embedded therein an anchor bolt, said plural concrete boulders arranged in a row in front of a structure to be protected from erosion;
- a plurality of anchor mechanisms located on a land side of said structure, each said anchor mechanism anchored on the land side of said structure;
- and
- one or more cables extending between respective anchor bolts of said concrete boulders and the land side anchor mechanisms so that said cables overlie said structure to be protected from erosion.
A method for preventing erosion of soil by water, said method comprising:
- fabricating a plurality of concrete boulders, each concrete boulder fabricated so as to have embedded therein an anchor bolt, and arranging said plural concrete boulders in a row in front of a structure to be protected from erosion;
- placing anchor mechanisms on a land side of said structure, and anchoring said anchor mechanisms in ground material located on the land side of said structure;
- and
- extending one or more cables between each said concrete boulder anchor bolt and said land side anchor mechanisms so that said cables overlie said structure to be protected from erosion.
