Two-stage mechanically-stabilized retaining earth wall and method
View Patent ↗A two-stage retaining wall and related systems and methods are disclosed. The wall may include a welded-wire earth wall comprising a plurality of generally horizontal bars. The wall may include a foundation spaced apart from the welded-wire earth wall. The wall may include a plurality of concrete panels positioned on the foundation to form a concrete wall. Each concrete panel may include at least one pair of loop anchors disposed on a back face, wherein the back face faces the welded-wire earth wall. The wall may also include a plurality of connector assemblies, each of which may include a rebar hook and a threaded bar. The rebar hook is adapted for engagement with the generally horizontal bars on the welded-wire earth wall. A first end of the threaded bar may be threadably engaged with the rebar hook and a second end of the threaded bar may be adapted for connection to one of the pair of loop anchors. Each threaded bar is preferably connected to a pair of loop anchors on each of the concrete panels in a substantially horizontal plane.
1. A two-stage retaining wall comprising:
a welded-wire earth wall comprising a plurality of generally horizontal bars;
a foundation spaced apart from the welded-wire earth wall;
a plurality of concrete panels positioned on the foundation to form a concrete wall, each concrete panel including at least one pair of loop anchors disposed on a back face, the back face facing the welded-wire earth wall;
a plurality of connector assemblies, each connector assembly including a rebar hook and a threaded bar, the rebar hook being adapted for engagement with the generally horizontal bars on the welded-wire earth wall, a first end of the threaded bar being threadably engaged with the rebar hook and a second end of the threaded bar being adapted for connection to one of the pair of loop anchors, wherein at least one threaded bar is connected to one of the pair of loop anchors on each of the concrete panels in a substantially horizontal plane, and
a bridging channel having a plurality of apertures, the bridging channel being connected between (a) a first pair of loop anchors on a first one of the concrete panels and (b) a second pair of loop anchors on a second one of the concrete panels that is adjacent the first one of the concrete panels.
