Abstract
Abstract An angulated retaining wall comprised of a plurality of adjoining posts is disclosed for retaining a wall of material having gradual and/or abrupt changes in direction in its face. The retaining wall is comprised of corner-groove combinations wherein a corner of a post is disposed at a desired direction into a groove of an adjoining post and wherein the preferred angularity of said groove is less than that of the predetermined angularity of said corner. At the maximum disposition a first side of a corner will be parallel to and overlap in supportive contact with a first sidewall of said groove by a predetermined dimension between said corner and the edge of the first sidewall, and the adjacent side of said corner will be in supportive contact with the edge of the second sidewall of said groove. At an intermediate disposition the first side and the adjacent second side of said corner will be in supportive contact with the edges of the first sidewall and the second sidewall respectively of said groove. Starter posts, line posts, key posts, corner posts, and end posts are disclosed.
