Patent ID: 7686539

Claim:
A water movement device comprising a flexible wall placed in water close to a surface of water, substantially vertically in a static rest state, made up of optionally perforated massive unit blocks assembled to one another in strings by cables on which said blocks are threaded or on which said blocks are crimped, said cables comprising: a first series of cables disposed vertically and side by side, parallel to one another; and a second series of cables disposed horizontally one above another and in parallel; and each block is pierced through in the vertical direction and in the horizontal direction, so as to enable at least one said vertical cable and at least one said horizontal cable to pass therethrough, and each said block is assembled to at least one vertical cable, thereby forming a plurality of parallel vertical cable strings, and at least some of said blocks, thereby assembling the various vertical cable strings to one another, and said vertical cables being suspended or tensioned at their top ends and/or respectively tensioned or moored at their bottom ends; and said blocks are assembled in strings with each block having a top face and a bottom face, wherein the top faces of lower blocks come against the bottom faces of higher blocks along said vertical cables; and said blocks are spaced apart from one another along said horizontal cables by pads and said blocks comprising: empty orifices passing through said blocks between the front and rear faces of said wall; and/or empty spaces between said blocks; whereby said orifices and/or empty spaces between said blocks confer overall porosity to said wall preferably representing 5% to 75% of the area of the vertical section of said wall.
