A reinforced retaining wall is provided comprised of precast, concrete block facing elements (12) connected by suitable connectors to reinforcing members (16) which extend from the facing elements (12) into the adjacent reinforced soil (18) to form a mechanically stabilized earthen wall construction. The connectors which affix the reinforcing members at their connecting ends to the facing elements comprise concrete (14) poured into a part on all of certain of the void spaces within selective facing blocks (12), which concrete (14) may or may not be reinforced and which concrete (14), when dry and cured, envelops and secures the connecting ends of the reinforcement members (16) to their corresponding blocks (12) and forms anchors thereat. In addition, wall constructions are provided having reinforcement members (16) with differing reinforcement characteristics placed at different elevations of a wall, as desired, to accommodate specific design requirements, such as, for example, soil nails, metallic grids and geotextiles, all of which are employed as reinforcements in a single wall construction.

L'invention concerne un mur de retenue armé, constitué d'éléments blocs de béton de parement (12) préfabriqués, reliés par des éléments d'attache appropriés à des éléments d'armature (16). Ces derniers partent des éléments de parement (12) et aboutissent dans la terre armée (18) adjacente, de façon à former une construction de mur en terre mécaniquement stabilisé. Les éléments d'attache, qui fixent les extrémités de connexion des éléments d'armature sur les blocs de parement, sont constitués de béton (14) coulé dans tout ou partie de certains espaces vides situés à l'intérieur des blocs de parement (12). Ledit béton (14) peut être armé ou non et, une fois sec, il enveloppe et fixe les extrémités de connexion des éléments d'armature (16) sur les blocs (12) correspondants et forme des ancrages à ce niveau. L'invention concerne également des éléments d'armature (16) ayant des caractéristiques d'armature différentes, placés à différentes hauteurs d'un mur en fonction des besoins, de façon à s'adapter à des exigences de conception spécifiques, par exemple aux pitons pour la terre, aux grilles métalliques et aux géotextiles employés comme armatures dans une construction de mur unique.
