Formed on a triangular bottom (7) are two thin plate-shaped side walls (2, 3) which are inclined towards one another and meet in an inclined front edge (5). Flanges (4, 6) on the side edges of the side walls (2, 3) extend vertically upwards from the bottom (7) and are provided with holes (9) for receiving a screw connection, by means of which adjacent wall elements are interconnected to form a noise-protection wall. <IMAGE>
