Retaining wall/tie-back/anchor assembly

Abstract

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.
