ABSTRACT:
A modular wall block is formed with a T-shaped through-opening defining arm sections projecting from a stem portion in each surface of the block. One arm section in the upper surface of each block is dimensioned to frictionally receive fingers of a rake-like connection device which may thereby secure an end portion of sheet of reinforcing material such as a geogrid or the like, to the block. The connection device includes enlarged tabs projecting away from the fingers to engage in a different width arm section defined in the lower surface of superimposed wall blocks for positioning the front faces of the blocks in the retaining wall relative to each other in either a vertically aligned or vertically set back relationship depending upon the direction of extension of the tabs. Stair-step sections of interconnected blocks may be interleaved to form a retaining wall. Additional connection devices may be inverted to further integrate juxtaposed stair-step sections. Likewise, the sheet of reinforcing material may span a plurality of blocks in each course to secure the stair-step sections to each other. The blocks may be used as corner blocks provided with similar aesthetic patterns on a front and a side surface for forming corner portions of sections of a retaining wall extending at right angles to each other.
