Benefits of technology
The present patent provides various embodiments of a mechanically stabilized earth (MSE) retaining wall that uses a geosynthetic strip for reinforcement. The geosynthetic strip attaches to the MSE retaining wall and extends into the backfill soil. The MSE retaining wall has concrete panels with a cavity for receiving the geosynthetic strip. The panels have a plastic pipe and a steel rod inside the panel for added strength. The geosynthetic strip extends from the backfill soil and wraps around the panels, providing stability. The technical effects of this patent include improved stability and reinforcement of the MSE retaining wall.
Problems solved by technology
Such walls are subjected to very high pressures exerted by lateral movements of the soil, temperature and shrinkage effects, and seismic loads.

Embodiment Construction
Earth Reinforcement Rod
[0048]An innovative soil reinforcement rod has been recently invented by the inventor for the earth retaining wall market. The new reinforcement rod 1 uses a new geometry of reinforcement, shown in FIG. 4, to be used to create a more efficient use of materials, notably steel, in the construction of mechanically stabilized earth (MSE) retaining walls 2, shown in FIG. 5A. A conventional MSE retaining wall 2 with steel reinforcement 13 is typically reinforced with steel strips 4 or welded wire mesh 6, shown in FIGS. 6-8, that extends perpendicular from the rear of a concrete panel 14 face to reinforce the backfill soil 15. The new earth reinforcement rod 1 was created when realizing that, as shown in FIG. 4, a solid singular round bar 11 with circular disks 3 placed along the length of the solid round bar 11 would be a more efficient and effective reinforcement. Capitalizing on passive earth pressure when pulling the disks 3 through the backfill soil 15, the disk...

Abstract
Disclosed are various embodiments of a mechanically stabilized earth (MSE) retaining wall that employ, for reinforcement, a geosynthetic strip that attaches to the MSE retaining wall and extends into the backfill soil. In one embodiment, the MSE retaining wall has at least one concrete panel. The panel has a cavity extending from the backside into the body for receiving a flexible, generally flat, geosynthetic strip. The panel has a plastic pipe (or first cylindrical body) that is situated within the body of the panel in a position so that the plastic pipe is generally horizontal from a front elevation view vantage point of the panel and is generally parallel with the backside of the panel from a top view vantage point of the panel. The plastic pipe extends through the cavity and its ends reside within the concrete panel. The MSE retaining wall further includes a steel rod situated inside of the plastic pipe. The geosynthetic strip extends from backfill soil adjacent to the backside of the panel, into the cavity of the panel, around the elongated body of the plastic pipe, out of the cavity, and into the backfill soil. In another embodiment of the MSE retaining wall, an end of the geosynthetic strip is bound to the panel with a double compression loop arrangement that utilizes an additional solid second plastic rod (or second cylindrical body).
