Abstract:
1. A mortarless retaining wall constructed of a plurality of segmented retaining wall (SRW) blocks stacked in an array of superimposed rows, each SRW block comprising: a face unit having a an opposing front face and back face, the front face being exposed and the back face having two connector elements and being hidden; an anchor unit having two connector elements and a cross member, the two connector elements each being of complementary shape to the face unit connector elements for interconnection therewith without other connectors, each connector of the face unit providing an interconnection with a respective one of the two connectors of the anchor unit to interlock the face unit and the anchor unit, the anchor unit confronting soil being retained by the retaining wall; the anchor unit and the face unit each having upper and lower load bearing surfaces, the upper load bearing surfaces for supporting the lower load bearing surfaces of a super-imposed stacked block, the face unit being made of concrete such that the load bearing surfaces resist shear forces between adjacent SRW blocks in order to retain the wall structure when subject to forces applied by the soil retained by the retaining wall against the SRW block, and the anchor unit and face unit interlocked via respective connector elements to form the SRW block, the anchor unit and the face unit, when interlocked, forming a hollow core between the back face of the face unit and the cross member and extending vertically from the upper load bearing surfaces to the lower bearing surfaces.
