Vegetation covered earth filled concrete noise absorbing screen - has long slabs screwed to ends of connecting beams in tapering tiers

摘要

Screen is in the form of an embankment made up from prefabricated concrete units, comprising elongated slabs running parallel to each other in pairs, partially enclosing an earth filling planted with vegetation. There are two prefabricated component connecting beams (2, 2', 2", 2''') which decrease in length from bottom to top (w, w', w", w'''). At the ends of these, pairs of elongated slabs (3) are screwed on, or otherwise detachably fastened, in a horizontal position. These pairs of slabs may be sited cantilevered outwards from the screen on both sides, pref. with the protruding sections (13) bent slightly upwards. The components are invisible in the overall structure, leaving only a green-clad earth wall on view.
