Abstract
Abstract A face panel system for forming an exposed face on a fill structure employs a succession of precast reinforced concrete panels which act first as a restraining form and then as a permanent exposed face for the structure. In one embodiment, successively higher rows of panels are supported by strongbacks mounted to a lower row of panels and extending upward therefrom to act as temporary cantilevered supports for the next higher row. In this manner, horizontal forces exerted by the fill mass are transferred back to the mass. Another embodiment features an internal cantilever support structure embedded in the panels, which are coupled together with brackets extending therefrom.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
113 words
A method of constructing a panel-faced fill structure comprising the steps of: placing successive rows of exposed substantially vertical panel members to form the permanent exposed panel face of said fill structure; placing a back fill mass against one surface of said successive rows of panels at the rows are placed; anchoring each of said panels with tieback members extending into the back fill mass of said structure as the successive rows are placed; and supporting each successive row of panels against the lateral shear and overturning forces of said back fill mass by means of supports cantilevered from the preceding row until said tieback members are held by said back fill mass.
Claim 2
Independent Claim
113 words
A method of constructing a panel-faced fill structure comprising the steps of: placing successive rows of exposed substantially vertical panel members to form the permanent exposed panel face of said fill structure; placing a back fill mass against one surface of said successive rows of panels at the rows are placed; anchoring each of said panels with tieback members extending into the back fill mass of said structure as the successive rows are placed; and supporting each successive row of panels against the lateral shear and overturning forces of said back fill mass by means of supports cantilevered from the preceding row until said tieback members are held by said back fill mass.
Claim 3
Independent Claim
161 words
A method for constructing a fill structure comprising the steps of: placing a generally horizontal first row of substantially vertical panels; back filling a fill mass against one substantially vertical surface of the panels of said first row, said first row of panels providing a facing form for said fill mass; vertically supporting a second generally horizontal row of substantially vertical panels upon said first row, one of the substantially vertical surfaces thereof being substantially coplanar with said one surface of said first row; securing said second row of panels against lateral shear and overturning forces acting against the said one surface thereof with support members cantilevered from said first row; then continuing the back filling of said fill mass against the one surface of said second row; and repeating the placement and support of succeeding rows of panels to form a permanent exposed panel face of said fill structure and back filling until the structure has reached a predetermined height.
Claim 4
Independent Claim
161 words
A method for constructing a fill structure comprising the steps of: placing a generally horizontal first row of substantially vertical panels; back filling a fill mass against one substantially vertical surface of the panels of said first row, said first row of panels providing a facing form for said fill mass; vertically supporting a second generally horizontal row of substantially vertical panels upon said first row, one of the substantially vertical surfaces thereof being substantially coplanar with said one surface of said first row; securing said second row of panels against lateral shear and overturning forces acting against the said one surface thereof with support members cantilevered from said first row; then continuing the back filling of said fill mass against the one surface of said second row; and repeating the placement and support of succeeding rows of panels to form a permanent exposed panel face of said fill structure and back filling until the structure has reached a predetermined height.
Claim 5
Dependent Claim
28 words
The method of claim 2 including the step of: anchoring each panel of each said successive row with tieback members extending from said panels into said fill mass.
Claim 6
Dependent Claim
55 words
The method of claim 3 wherein said cantilevered support members are mounted to the substantially vertical surface of the panels of the first row opposite said one surface thereof and including the step of removing said cantilevered support members from the panels of the first row after the panels of the second row are anchored.
Claim 7
Dependent Claim
27 words
The method of claim 3 wherein the step of anchoring each panel with tieback members includes the steps of threadedly securing the tieback members in said panels.
Claim 8
Dependent Claim
51 words
The method of claim 2 wherein the support members are at least partially embedded in said panels and wherein the step of securing said second row of panels includes the step of coupling said panels in said second row to said panels in said first row along their adjacent horizontal edges.
Claim 9
Independent Claim
141 words
A method for constructing a fill structure comprising the steps of: placing a first substantially horizontal row of panels, said panels having an exposed face and a fill contacting face; cantilevering support members from the exposed face of said panels with the cantilevered support members extending substantially vertically upward; back filling a fill mass against the fill contacting face of said panels in said horizontal row; extending a plurality of tiebacks from the panels into the fill mass; placing a substantially horizontal second row of panels upon the first row, said second row being supported against laterally directed shear and overturning forces by the cantilevered support members; and repeating the steps of cantilevering support members, backfilling, extending tiebacks, and placing rows of panels to form a permanent exposed panel face of said fill structure until the structure reaches a predetermined height.
Claim 10
Independent Claim
