Wall retention system

A wall retention system having precast modular components, for abutting against and retaining a mass of earth, comprising in combination:

• (a) a set of flat facing slabs, adapted to interlock with one another to form a single continuous wall structure, each said facing slab having an outer flat surface and an inner, reinforced surface;
• (b) interlocking means, for sidewisely interlocking said facing slabs to form said single continuous wall structure;
• (c) foundation slabs, adapted for ground engagement, and defining integral means for supporting and anchoring the lower portions of said facing slabs wherein said facing slabs are supported in generally upright condition;
• (d) a number of sets of elongated tension members, each of said sets of tension members having at least three vertically spaced tension members integrally carried at their inner ends by the same single corresponding said facing slab reinforced surface and transversely projecting therefrom at vertically spaced intervals, said tension members adapted to embeddingly anchor into said mass of earth to be retained;
• wherein each of said elongated tension members includes:
• (a) first and second straight, elongated brace bars, defining inner and outer ends;
• (b) bracket means, fixedly anchoring said inner ends of said first and second straight brace bars to laterally offset raised sections of said reinforced surface of facing slabs;
• and
• (c) a third arcuate brace bar, fixedly interconnected by bolt means to said outer ends of said first and second straight brace bars, with the convex side of said arcuate brace bar extending away from said facing slabs;
• wherein said first to third brace bars are installed behind the facing slabs within a trenched earthless area;
• wherein said third arcuate brace bars of laterally adjacent sets of tension members are fixedly interconnected in successive lateral pairs of third arcuate brace bars by the same said bolt means, so that all said sets of tension members are accordingly interconnected in successive pairs at their outer ends wherein an integral massive open ground anchoring array is formed;
• wherein large horizontal loadings from the mass of earth can be sustained by said wall retention system, without compromising the angularity of said facing slabs relative to ground level.
