The invention relates to a two-shell component for setting up plantable steep embankments formed from several layers. The component consists of a front element (1) with a three-dimensional lattice structure, which is resistant to bending, a spacer element (2) and a rear wall element (3). It is an essential element of the invention that the cross section of the rear wall element (3), which is permanently resistant to bending, follows a polygon curve or a straight line in the vertical direction. The pressure resistant spacer element (2) is shaped by notches (4) at least at one place and has holding devices (5) for frictional connections with the geoplastics (7). Connecting means (6), with which the elements (1, 2, 3) of the component may be connected positively and frictionally, are mounted at least at two place of the spacer (2). The component is intended for use as a standalone supporting system, which permanently absorbs the horizontal effects resulting from the pressure of the earth from the back filling.

La présente invention concerne une pièce de construction double-paroi permettant l'érection de murs-talus végétalisables faits de plusieurs couches, la pièce se composant d'un élément frontal (1) qui présente une structure maillée spatiale résistant à la flexion, d'un élément d'espacement (2) et d'un élément de paroi arrière (3). Selon l'invention, la section de l'élément de paroi arrière (3) résistant durablement à la flexion suit en direction verticale un tracé polygonal ou une ligne droite. L'élément d'espacement (2) résistant à la compression est formé en au moins un emplacement par des entailles (4) et présente des éléments de retenue (5) permettant de réaliser des liaisons à force avec les géosynthétiques (7). Au moins un moyen de liaison (6) est mis en place sur l'élément d'espacement (2) en au moins deux emplacements, les moyens de liaison permettant aux éléments (1, 2, 3) de la pièce de construction d'être reliés à force et par complémentarité de forme. La pièce de construction peut être employée en tant que système de support indépendant qui résiste à long terme aux contraintes horizontales résultant de la pression exercée par la terre suite aux opérations de remblaiement.
