14. A wall system as defined in claim 9 wherein said secondary reinforcing members extending generally throughout said retaining wall comprise elongated metal reinforcing fibers.
15. A wall system as defined in claim 9 wherein said secondary reinforcing members extending generally throughout said retaining wall comprise a mesh of reinforcing wires substantially smaller than said primary reinforcing bars.
16. A precast concrete retaining wall system adapted for use as a wing wall for a concrete culvert to retain a backfill of soil, comprising a precast concrete retaining wall adapted to be supported by a concrete footer, reinforcing members extending generally throughout said retaining wall, at least one precast concrete anchor member including an outer flange wall and an integrally connected generally vertical web wall connecting said flange wall to said retaining wall, elongated reinforcing rods extending within said web wall of said anchor member and including internally threaded tubular anchors embedded within said retaining wall, and said reinforcing rods within said web wall of said anchor member comprise tie rods rotatably supported within ducts within said web wall and having threaded end portions connected to said tubular anchors within said retaining wall.
17. A wall system as defined in claim 16 wherein said tie rods have threaded outer end portions projecting from said web wall of said anchor member, and nut members threaded onto said outer end portions of said tie rods.
18. A wall system as defined in claim 17 wherein at least one said threaded tubular anchor is embedded within said retaining wall on an incline relative to said retaining wall and above said precast anchor member, and one of said tie rods is inclined relative to said retaining wall and has a threaded upper end portion threaded into said one tubular anchor.
19. A wall system as defined in claim 16 wherein said reinforcing members extending generally throughout said retaining wall comprise elongated metal reinforcing fibers.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
