ABSTRACT:
A soil retaining system, including an upright soil retaining wall of modular facing panels and a number of horizontal wire mesh reinforcement units, including spaced parallel wires ending in bulbous portions and interconnected by perpendicular crossbars. The mesh units are connected in tiers to the retaining wall and rest in the soil behind the wall. The connection is made by a female member embedded into the back side of the panel with internal threads, into which a male member is threadedly received with an internal bore of a suitable size to pass the wires but not the bulbous portions which bear against the forward end of the bolts. In this manner, with the wires seated within a corresponding male member, the facing panels and mesh units are connected by screwing the male member into the female member.
