Patent ID: 7862253

Claim:
Wave protection structure for a slope, which slope merges into a bed at the location of a toe, which wave protection structure comprises a plurality of wave protection elements and a plurality of toe elements, wherein the wave protection elements are each provided with a plurality of projections, which plurality of projections together form a three-dimensional structure for the wave protection elements to engage in one another in such a manner that the freedom of movement of the wave protection elements is limited in three dimensions, and the wave protection elements on the slope are provided in a substantially regular imaginary grid, with a horizontal grid spacing between the centres of gravity of the wave protection elements, while the toe elements extend in a longitudinal direction of the toe in order to counteract displacement of the wave protection elements from the slope to the bed, and are of a shape which deviates from the shape of the wave protection elements, where in the centres of gravity of the toe elements, in the longitudinal direction of the toe, are provided at substantially the same horizontal grid spacing from one another as the wave protection elements, and the shape of at least one of the toe elements is substantially identical to the shape of the wave protection element from which at least one projection has been omitted in order to form a supporting surface for the toe element.
