Abstract
An underwater soil retention and reinforcement structure comprises a sequence of synthetic buoyant fronds (11) arranged side-by-side to form a frond line. The frond line is folded back and forth to form an array of fronds, and the successive folded sections (14) of the frond line have aligned openings (20) threaded by at least one anchor line (19) for anchoring the array to the soil bed.
Claims12
An underwater soil retention and reinforcement structure comprising a sequence of synthetic buoyant fronds arranged side-by-side to form a continuous line of fronds, the lines being folded back and forth to form a fanfold array of frond sections, each of the successive folded sections of the array having at least one aligned opening threaded by at least one anchor line for anchoring the array to the soil bed.
A method of deploying an underwater soil retention and reinforcement structure, the structure comprising a line of buoyant fronds folded back and forth to form a fanfold array, the array being threaded by at least one transverse anchor line, the method comprising retaining each anchor line in a box-like dispenser with the fanfold sections of the frond line in a bunched, compact state, and the fronds lying flat, lowering the dispenser to the soil bed, anchoring one end of each anchor line to the soil bed, and thereafter advancing the dispenser over the soil bed such that the anchor line is progressively withdrawn from the dispenser and the fronds are released into an upright buoyant state.
