Abstract
Abstract A retaining system for an earthen formation is disclosed. The earthen formation is reinforced against slippage by embedding an array of anchor members within the formation. The face of the formation is defined by a plurality of the elongated panels stacked in a vertical arrangement. The anchor members are secured to the panels via a support bar. The support bar includes an array of holes through which the ends of the anchor members are received and upset to define a rivet head. The support bars are engaged between the upper and lower edges of the face panels to provide support and maintain vertical alignment of the face panels.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
104 words
A retaining system for an earthen formation comprising: a plurality of elongated face panels stacked above one another to define a wall; a plurality of anchor members disposed within the earthen formation behind the stacked face panels, said members being arranged in a spaced-apart generally parallel array; and a plurality of support bars disposed between and engaged with rows of face panels of said wall, at least certain of said support bars having an array of holes extending therethrough; and at least certain of said anchor members having ends extending through said holes and upset to secure the anchor members to the support bars.
Claim 2
Dependent Claim
104 words
A retaining system for an earthen formation comprising: a plurality of elongated face panels stacked above one another to define a wall; a plurality of anchor members disposed within the earthen formation behind the stacked face panels, said members being arranged in a spaced-apart generally parallel array; and a plurality of support bars disposed between and engaged with rows of face panels of said wall, at least certain of said support bars having an array of holes extending therethrough; and at least certain of said anchor members having ends extending through said holes and upset to secure the anchor members to the support bars.
Claim 3
Dependent Claim
25 words

Claim 9
Independent Claim
113 words
A method of constructing a retaining system for an earthern formation comprising the steps of: securing elongate earth anchor members to support bars by extending the ends of the members through holes in the bars and riveting the ends over; laying successive rows of elongated face panels at the intended face of the formation in generally stacked relationship; successively filling the area behind said rows of face panels with earth as said successive rows are laid; successively laying said earth anchor members over said earth as it is successively filled, with said members being disposed in spaced apart generally parallel relationship and the support bars on said members captured between the stacked panels.
Claim 10
Independent Claim
113 words
A method of constructing a retaining system for an earthern formation comprising the steps of: securing elongate earth anchor members to support bars by extending the ends of the members through holes in the bars and riveting the ends over; laying successive rows of elongated face panels at the intended face of the formation in generally stacked relationship; successively filling the area behind said rows of face panels with earth as said successive rows are laid; successively laying said earth anchor members over said earth as it is successively filled, with said members being disposed in spaced apart generally parallel relationship and the support bars on said members captured between the stacked panels.
Claim 11
Dependent Claim
61 words
A method as recited in claim 8 wherein said anchor members are riveted to said support bars with the following steps: providing an array of holes in each said support bar; passing the ends of the anchor members through the holes in the support bar; upsetting the ends of said anchor members to secure the anchor members to said support bar.
Claim 12
Dependent Claim
109 words
An improved retaining system for an earthen formation which includes a plurality of elongated face panels stacked above one another to define a wall and a plurality of anchor members disposd within the earthen formation behind the stacked face panels, said members being arranged in a spaced-apart array extending away from said face panels, with the improvement comprising: elongated support bars secured to at least certain of said anchor members, said support bars being captured between said face panels and having arrays of holes through which ends of said certain anchor members extend; and upset heads on said ends to provide a riveted connection between said ends and bars.
Claim 13
Dependent Claim
109 words
An improved retaining system for an earthen formation which includes a plurality of elongated face panels stacked above one another to define a wall and a plurality of anchor members disposd within the earthen formation behind the stacked face panels, said members being arranged in a spaced-apart array extending away from said face panels, with the improvement comprising: elongated support bars secured to at least certain of said anchor members, said support bars being captured between said face panels and having arrays of holes through which ends of said certain anchor members extend; and upset heads on said ends to provide a riveted connection between said ends and bars.
Claim 14
Dependent Claim
98 words
