Claim 15

Dependent Claim 70 words

A retaining wall according to claim 1 wherein the retention structure comprises a primary retention rod secured to the anchor member for extension across the face of an earthen formation to be reinforced; and a plurality of secondary retention rods releasably engaged with said primary rods so as to extend across the face of an earthen formation to be reinforced in a direction generally normal to the primary retention rod.

Claim 16

Independent Claim 157 words

A method of constructing a retaining wall for an earthen formation, said method comprising: embedding a plurality of anchor members in the formation in vertically spaced relationship to one another so that the distal ends thereof are located proximate the face wherein it is desired to locate the wall; providing a retention structure for each of the anchor members, said structures being secured to the anchor members in generally parallel relationship to one another and in a plane generally coincident with the face wherein it is desired to locate the wall; securing extensions relative to at least certain of the anchor members, said extensions protruding outwardly relative to the retention structures; securing form panels to the extensions in spaced relationship to the retention structures; forming a concrete wall against said form panels in the space between said panels and the retention structures; and back-filling the space between the earthen formation to be reinforced and the retention structures.

Claim 17

Independent Claim 157 words

A method of constructing a retaining wall for an earthen formation, said method comprising: embedding a plurality of anchor members in the formation in vertically spaced relationship to one another so that the distal ends thereof are located proximate the face wherein it is desired to locate the wall; providing a retention structure for each of the anchor members, said structures being secured to the anchor members in generally parallel relationship to one another and in a plane generally coincident with the face wherein it is desired to locate the wall; securing extensions relative to at least certain of the anchor members, said extensions protruding outwardly relative to the retention structures; securing form panels to the extensions in spaced relationship to the retention structures; forming a concrete wall against said form panels in the space between said panels and the retention structures; and back-filling the space between the earthen formation to be reinforced and the retention structures.

Claim 18

Dependent Claim 26 words
