Abstract:
Revetment for a water-retaining structure, comprising elements (1) of concrete resting against each other, which elements are approximately prismatic in the height direction and each have two transverse faces (7, 8) and two longitudinal faces (5, 6) between a top face (3) and a bottom face (2), which revetment has open spaces extending between the top faces (3) and bottom faces (2), for allowing water to pass through,wherein one transverse face (7) of each element is made a concave shape and the other transverse face (8) is made a corresponding convex shape, at least one of the transverse faces (7, 8) and/or longitudinal faces having a recess (9, 10), in such a way that the elements rest with their transverse faces against each other in various rotated positions, and the recesses (9, 10) each bound an open space with an opposite wall (5-8) and/or recess (9, 10) of an adjacent element, and wherein the elements (1) form rows (12) in which the transverse sides (7, 8) in each row rest against each other and elements (1) from adjacent rows rest with their longitudinal sides (5, 6) against each other.
