A retaining wall assembly having a plurality of face plates, which interlock with tie-backs. The face blocks in one embodiment 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 flange, interlocks with four adjacent face plates. The tie-backs have anchors which provide stability and anti torsion, and comprise elongated rods joined to a key block at a forward end, which is further provided with a stiffener plate. The back feet, which are preferably rebars, are welded to the key block and extend rearwardly therefrom. A plurality of anchor plates are arranged at spaced (preferably equi-spaced) intervals therealong and are joined thereto preferably by welding. Tie-backs of a plurality of lengths N.times.K are provided where N is a real integer and K is a given length. In addition, tie-back extensions may be joined to a tie-back or another tie-back extension in the field. At least one anchor plate of a tie-back and at least one anchor plate of a tie-back extension are interlocked and then bolted together after being interlocked to extend tie-back lengths where necessary in the field. The rebar, together with the anchors and key plates are preferably formed of galvanized steel.

Retaining wall/tie-back/anchor assembly

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.
