A construction element is disclosed for retaining a soil mass. In general, the construction element comprises a face panel and a plurality of protruding arms. The face panel has a forward wall, a rearward wall, side walls and a top and bottom wall. Such protruding arm extends from the rearward wall of the face panel, and each have an upper wall, lower wall, a back wall and side walls. The upper and lower walls of these protruding arms are each provided with engaging means for facilitating stacking of at least a portion of the protruding arm of one construction element, on top of at least a portion of the protruding arm of another construction element, and for preventing relative sliding movement therebetween. These construction elements can be used to construct a retaining wall and soil reinforcement subsystem, which comprises one or more free-standing retaining wall construction elements and at least one grid structure positioned behind each such construction element. In such a subsystem, the grid structures interlock with the soil beyond said face panel and create a substantially self-supporting, stable reinforced soil mass free of failure planes, permitting retaining wall heights that far exceed the height of the individual construction elements. Also disclosed is apparatus for molding the retaining wall construction elements of the present invention. |
