Abstract
Extended lengths of grid-like reinforcing sheet material are attached to precast wall panels of a reinforcing wall by a connector comb and locking clip securing end portions of the reinforcing sheet material between a pair of attachment strips partially embedded in, and extending rearwardly from, the wall panels. The comb connector includes a spine and plurality of upwardly projecting fingers engageable through aligned openings in the attachment strips and the reinforcing sheet material used for soil reinforcement. The locking clip is interengaged with ratchet-like serrated edges formed on the free ends of the fingers of the comb to secure the reinforcing sheet material to the attachment strips.
