<p>The wall, such as may be erected alongside a motorway or the like, consists of a number of separate elements (1-3) placed side by side and on top of one another to form a lattice pattern (which may be filled or partially filled with earth). The elements are roof-shaped with open ends (e.g. U-shaped as shown or V-shaped etc) whilst the upper ends and the lower ends of the sides (1,2) are provided with complementary profiles e.g. recesses (4,5) with zig-zag profile bottoms (7,8) at the upper ends and zig-zag profiles (9, 10) at the lower ends. When superimposed, e.g. with ends (9) of one element in recess (8) of another element etc., the elements are located relative to one another and form e.g. a honeycomb pattern.</p> |
