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.

Dependent claims

A stabilized retaining wall structure comprising:

a) a plurality of individual blocks stacked in an array of superimposed rows, with at least one hollow core being formed in selected blocks of said individual blocks, with said selected block comprising a rear surface and an access bore, with said access bore running from said rear surface to said hollow core such that said hollow core can be accessed from a rear of said selected block;
b) an earthen fill zone in spaced apart relation to said rear surfaces of said selected blocks;
c) clean granular back-fill interposed between said earthen fill zone and said rear surfaces of said selected blocks;
d) a stable anchoring assembly disposed in said earthen fill zone and being coupled to and in restraining contact with said selected blocks;
e) a keeper engaged in the hollow core of said selected block;
and
f) an elongated connector running between said keeper and said stable anchoring assembly, with the elongated connector comprising a body segment and opposed proximal and distal ends, with said proximal end of said elongated connector being engaged with said keeper, with the elongated connector being in the access bore of said selected block and running from the access bore of said selected block, with said distal end comprising an anchoring assembly attachment means, with said anchoring assembly attachment means being secured to said stable anchoring assembly.

A stabilized retaining wall structure comprising:

a) a plurality of individual blocks stacked in an array of superimposed rows, with at least one hollow core being formed in selected blocks of said individual blocks, with said selected block including a rear surface;
b) with said selected block further comprising a front web portion, a rear web portion, and a pair of side web portions interconnecting the front and rear web portions;
c) with said rear web portion of said selected block comprising an access bore formed therein such that said hollow core can be accessed from the rear surface of said selected block;
d) with said selected block further comprising an inner surface, wherein said inner surface comprises a rear inner surface portion defined by the rear web portion, side inner surface portions defined by the side web portions, and a front inner surface portion defined by the front web portion;
e) an earthen fill zone in spaced apart relation to said rear surfaces of said selected blocks;
f) a clean granular back-fill interposed between said earthen fill zone and said rear surfaces of said selected blocks;
g) a stable anchoring assembly disposed in said earther fill zone for being coupled to and in restraining contact with said selected blocks;
h) a keeper engaged in the hollow core of said selected block, wherein said keeper comprises a metal bracket structured to include a rear bracket portion confronting the rear inner surface portion of said rear web portion of said selected block and a pair of side bracket portions confronting the side inner surface portions of said side web portions of said selected block;
and
i) a pair of elongated connectors running between said metal bracket and said stable anchoring assembly, with each of said elongated connectors comprising a body segment and opposed proximal and distal ends, with said proximal end of each of said elongated connectors being engaged with the rear bracket portion of said metal bracket, with each of said elongated connectors being in one respective access bore of said rear web portion of said selected block and running from said access bore, with said distal end comprising an anchoring assembly attachment means that comprises a hook, and with said anchoring assembly attachment means being secured to said stable anchoring assembly.
