ABSTRACT:
A stablized retaining wall structure comprising concrete blocks stacked in an array of superimposed rows, and with a stable anchoring assembly being in restraining contact with selected blocks. An access bore extends from the rear surface of the block to the surface of the wall comprising the hollow core. An earthen fill zone is arranged in spaced apart relationship to the rear surface of the wall and clean granular back-fill is interposed between the wall and the earthen fill zone. A keeper device is provided to couple selected wall blocks to the stable anchoring assembly, with the keeper device being configured to be restrainably held within the hollow core. An elongated fastener is coupled to the keeper device, with the fastener extending through the access bore and secured to the stable anchoring assembly.
