A vegetative noise protection device comprises two side
walls (1, 2), the space between the side walls (1, 2) being
filled with a substrate (3). The side walls (1, 2) are
erected from wall elements (4) formed by closely adjacent
willow branches (5) extending from the top to the bottom and
clamped between clamping rods (6, 7) extending in the
longitudinal direction of the wall. On the outside of each wall
element (4) there are at least two supporting poles (9)
protruding into the subsoil (10). The supporting poles (9) on
the two side walls (1, 2) are inclined toward each other and
interconnected by threaded rods (12). Between the willow
branches (5) and the space filled with substrate (3) there is
a root-permeable textile material (8).
La présente invention a pour objet un écran antibruit à structure végétale comportant deux parois latérales (1 et 2) retenant un substrat (3). Les parois latérales (1 et 2) sont constituées de branches de saule (5) rassemblées en rangs serrés de haut en bas et formant deux parois (4) retenues par compression à l'aide de tiges de serrage (6 et 7) réparties dans l'axe longitudinal du mur. En appui sur la surface extérieure de chacune des parois (1 et 2), au moins deux poteaux (9) enfoncés dans le sol (10) assurent le support de la structure. Les poteaux de soutien (9) disposés de part et d'autre des parois latérales (1 et 2) sont inclinés l'un vers l'autre et reliés par des tiges filetées (12). Une matière textile (8) permettant le passage des racines est interposée entre les branches de saule (5) et le massif structural (3).
