1. Sound insulation wall comprising constructional elements having one substantially prismatic leg with end pieces forming angles at both ends projecting from said leg, said end pieces extending parallel to each other and showing an S-configuration together with the leg, the top view of the constructional elements showing a latticed arrangement, adjacent end pieces of adjacent constructional elements overlapping each other and the spaces defined by the constructional elements passing through the full height of the sound insulation wall and being open when viewed from the top, characterized in that the constructional elements (8) are arranged like a slidable lattice grate and that the spaces (17) have a hexagonal cross-section when viewed from the top and are perforated when viewed from the front. |
