Abstract

A retaining wall assembly having a plurality of face plates which interlock with tie-backs. In one preferred embodiment, the face blocks have a substantially cross-shaped front face and recesses along top, bottom, left and right-hand sides which interlock with tie-back flanges. Each tie-back, through its interlocking flanges, interlocks with four adjacent face blocks. The tie-backs have back feet or anchors providing features of stability and anti-torsion. The tie-backs may utilize elongated rods which are joined interlocking key blocks as well as one or more anchors arranged at spaced intervals along the rods. At least the interengaging portions of the tie-backs and face plates are cast of highly durable casting material such as concrete, which is non-corrosive. The face plates have flat front and rear faces or, in another preferred embodiment, have flat front faces and integral rearwardly extending projections respectively provided with the top, bottom, left and right recesses which cooperate with the interengaging flanges. In another alternative embodiment, each of the face plates have a rectangular-shaped face and are provided with T-shaped grooves along their upper and lower sides for receiving and being interlocked with the interlocking flanges of at least four tie-backs. Each face panel typically interlocks with four adjacent face panels by way of the intermediate tie-back interlocking flanges.
