Abstract: A loop and saddle assembly includes a loop member and a saddle member. The loop member may include multiple layers (preferably 4 layers) of a geosynthetic material. The saddle member may have a curved seating surface adapted for cooperative engagement with the inner surface of the loop member. The saddle member may include a first generally planar truncated end at a first end of the curved seating surface and a second generally planar truncated end at a second end of the curved seating surface. The saddle member may include a lower surface with a concave profile extending from the first truncated end to the second truncated end. The loop member may be cast into a precast concrete panel with a portion of the loop member extending out of the precast concrete panel. The saddle member may be disposed in cooperate engagement with the loop member inside the loop member.

Abstract: A crimped connection system and methods for use in connection with the construction of earth walls is disclosed. A grid-type soil mat may be provided with a number of crimped ends. The crimped ends may be adapted for engagement through the use of a locking member with another soil mat or with a plurality of anchors partially embedded within a precast concrete panel. The plurality of anchors may be formed as part of a gang or unitary structure to facilitate alignment of the anchors when being cast into the precast concrete panels.

Abstract: 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.

Abstract: A skewed end assembly for connection to an arch culvert structure is provided. The assembly may generally include an arch-shaped inner skewed panel and a wedge member having a partially arch-shaped profile adapted for engagement with the inner skewed panel. The inner skewed panel may include a ledge that may include a plurality of threaded anchors. The wedge member may include a lip adapted for engagement with the ledge. The lip may include a plurality of apertures for receiving a plurality of threaded connectors adapted for threadable engagement with the corresponding threaded anchors in the ledge. Two assemblies, each comprising an inner skewed panel and a wedge member, are placed at opposed ends of an arch-shaped bridge or culvert structure to provide generally co-planar skewed ends to the structure such that it may be positioned at an angle in relation to a roadway such that the skewed ends are generally parallel to the roadway.

Abstract: A mechanically stabilized earth wall system, including an upright retaining wall of modular facing panels and a number of horiontal reinforcement units or anchors, including a novel connector to simply and quickly connect the horizontal reinforcement anchors to the modular facing panels.
