ABSTRACT:
An improved retaining wall construction includes a plurality of prefabricated, substantially upstanding soil retention panels connected together to define a wall facing. Each soil retention panel has a bottom surface with at least one cutout portion for receiving a lifting arm to lift and transport the soil retention panel, a first end having a projecting portion and a second end having a cutout slot. The projecting portion of one soil retention panel engages the cutout slot of anothe adjacent soil retention panel to form a keyed construction joint.
Earth is exacavated along a line demarking the wall construciton, and a concrete leveling pad is placed along the line. The soil retention panel is positioned on the leveling pad by means of an apparatus for lifting having lifting arms that are slidably engageable into the cutout portion of the soil retention panel. The lifting apparatus includes means for attaching the lifting apparatus to a lifting crane and means for holding the soil retention panel on the lifting arms until the soil retention panel is positioned and anchored.
