Interlocking prefabricated retaining wall system

Claim 2

A prefabricated retaining wall system for constraining soils of various types comprising: (a) a plurality of tie bar components of slab like configuration having a rectangular cross section, upper and lower planar surfaces for horizontal engagement with lower and upper surfaces of tie bar components situated below and above, a front planar surface to produce, in conjunction with other front surfaces, a front face of the retaining wall, a rear planar surface to constrain the soil therebehind, longitudinal ends having notches centrally positioned therein, semicircular projections extending rearwardly at each end tangential to said ends containing apertures therethrough, (b) a plurality of filler components of the same cross section as said tie bar components, with longitudinal ends having projections for engaging notches in said tie bar components, (c) a first horizontal tier having in alternating placement upon the earth tie bar components and filler components with notches and projections in fixed engagement, a second tier of similar alternating arrangement of components placed upon said first tier, third and additional tiers to result in the retaining wall front face having a height required by the soil to be constrained, and (d) a plurality of post components disposed through said apertures to secure the tier bar components and filler components to the earth below creating a unitized structure.

Claim 3

The retaining wall system as described in claim 1 wherein said tie bar components and said filler components are of cementicious material.

Claim 4

The retaining wall system as described in claim 1 wherein said tie bar components and said filler components are of steel reinforced concrete.

Claim 5

The retaining wall system as described in claim 1 wherein said notches and projections contain reverse angle surfaces to lock the components in contact preventing separation in the longitudinal direction.

Claim 6

The retaining wall system as described in claim 1 further comprising: (a) a plurality of T shaped components of the same cross section as said tie bar components, having a stem portion with an end plane surface and having notches on both sides proximate to the end plane surface, and a vertical aperture therethrough, (b) a horizontal tier having in alternating placement T components and filler components with said notches and projections in fixed engagement, said tier placed between said tiers of tie bar and filler components to provide a deadman anchor type unitized structure.

Claim 7

The retaining wall system as described in claim 5 further comprising: (a) a plurality of key components having the same size and structure as the stem portion of said T components including the end plane, notches on both sides proximate the end plane surface, and the aperture therethrough, (b) horizontal placement of said key components in said tier in place of T components so that the tier can be arranged with a variable number of T components, with key components located where T components are omitted.

Claim 8

A prefabricated retaining wall system for constraining soils of various types comprising: (a) a plurality of filler components of a slab like configuration having a rectangular cross section, upper and lower planar surfaces for horizontal engagement with lower and upper surfaces of filler components situated below and above, with longitudinal ends having projections centrally positioned therefrom, (b) a plurality of T shaped components of the same cross section as said filler components having a stem portion with an end plane surface and notches on both sides proximate the end plane surface and a vertical aperture therethrough, having a cross arm portion of said T with notches at the extremities of said cross arm, (c) a first horizontal tier having in alternating placement upon the earth, filler components and T components with projections and notches in fixed engagement, forming a straight front wall face with said T cross arms extending rearward, and filler components placed horizontally between the cross arms of subsequent T components to form closed rectangular configurations in the horizontal plane, (d) a second and additional horizontal tiers of components placed upon lower tiers to result in the retaining wall front face having a height required by the soil to be constrained, and (e) a plurality of post components disposed through said apertures to secure the T shaped components to the earth below creating a rigid, crib type, unitized structure.

Claim 9

A prefabricated retaining wall system for constraining soils of various types comprising: (a) a plurality of filler components of a slab like configuration having a rectangular cross section, upper and lower planar surfaces for horizontal engagement with lower and upper surfaces of filler components situated below and above, with longitudinal ends having projections centrally positioned therefrom, (b) a plurality of T shaped components of the same cross section as said filler components having a stem portion with an end plane surface and notches on both sides proximate the end plane surface and a vertical aperture therethrough, having a cross arm portion of said T with notches at the extremities of said cross arm, (c) a first horizontal tier having in alternating placement upon the earth, filler components and T components with projections and notches in fixed engagement, forming a straight front wall face with said T cross arms extending rearward, and filler components placed horizontally between the cross arms of subsequent T components to form closed rectangular configurations in the horizontal plane, (d) a second and additional horizontal tiers of components placed upon lower tiers to result in the retaining wall front face having a height required by the soil to be constrained, and (e) a plurality of post components disposed through said apertures to secure the T shaped components to the earth below creating a rigid, crib type, unitized structure.

Claim 10

The retaining wall system as described in claim 7 wherein said filler components and said T components are of cementicious material.

Claim 11

The retaining wall system as described in claim 7 wherein the components are prefabricated of steel reinforced concrete.

Claim 12

The retaining wall system as described in claim 7 wherein the projections and notches are of the reverse angle, locking type to prevent separation of the components in the longitudinal direction.
