ABSTRACT:
Individual precast concrete wall units for erecting a retaining wall structure each include a face member, a support member, and an anchor member. The support member has a front end portion, that is connected by a hinge to one end of the face member, and a rear end portion, that is connected to one end of the anchor member, either by a tongue-and-slot arrangement or by another hinge. The wall units can be cast straight, thus simplifying the design and reducing the space occupied by the mold. The wall units can also be transported and stored in the straight condition to save space. At the job site, the units are quickly and easily folded into an open bin-like form for placement side-by-side to construct a retaining wall.
