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).

A budding element for coupling with other budding elements to erect a retaining wall. Exemplary building elements have receiving spaces for receiving increased weight of fill material to provide increased stability. Optionally, each building element can have an enlarged face profile that provides efficiency in the shipping and assembly process. Optionally, each building element can define alignment voids that receive portions of alignment posts for ensuring vertical alignment between adjacent building elements or portions of building elements.

The present invention relates to an erosion control apparatus and methods of using and installing the apparatus. The apparatus is constructed to prevent erosion of soil during typical weather or tidal conditions and adverse weather events. The apparatus can include a plurality of anchored rolls and soil lifts operative to stabilize the shoreline.

The present invention provides an improved retaining wall system comprising a plurality of wall segments, said system comprising at least one lower wall segment and one upper wall segment, each of said upper and lower wall segments have a top surface, a bottom surface, a rear face, and a fascia, said top surface and said bottom surface extending between said rear face and said fascia, an earthen anchor extending at least partially through each of said wall segments and from said rear face, said earthen anchor configured for extending at least a portion of said vertical load of said retaining wall rearwardly; an interstitial surface; and an interconnecting structure extending into said interstitial surface and between said upper segment and said lower segment.

A soil reinforcing element and method of manufacturing for use in a mechanically stabilized earth (MSE) structure. A smooth metal strip is fabricated into a soil reinforcing element that is manufactured from stock pulled from a coil, the surface of the strip surface is manipulated using the technique of cold forming. Where the manipulated surface is optimized to consist of a peak and a valley to increase the pullout resistance when embedded in an earthen formation involving a mechanically stabilized earth (MSE) structure.

A soil reinforcing element including a flat elongated strip of material defining an upper planar surface and a bottom planar surface, the bottom planar surface opposing the upper planar surface, and a frictional profile being formed on each of the upper planar surface and the bottom planar surface, as well as a method of manufacturing the same.

A vertical manhole apparatus for use in a waste facility to provide access to one or more leachate collection pipe access points. The vertical manhole is stabilized using stabilizing features extending out from a vertical pipe of the vertical manhole apparatus.

A soil reinforcement strip (10, 30) for mechanically stabilizing earth structures. The strip (10, 30) has a polymer matrix (12, 32) which envelops elongated steel elements (14, 34) for reinforcing the matrix (12, 32). The steel elements (14, 34) may be steel cords containing a plurality of steel filaments (20, 22, 40, 42). Additionally, a reinforcement grid (60) for soil and ground. Furthermore, applications of this reinforcement strip (10, 30) and grid (60), namely to a reinforced soil layer (80) and to a mechanically stabilized earth structure or retaining wall (82).

A wale support module used to mount a wale on a soldier pile of a retaining wall, where the wale support module enables a groove defined between a soldier pile and a wale to be easily filled by a groove filling block, allows a groove filling block-side wale support or a pile support to pivot in response to the installation angle of an earth anchor to respond appropriately to the inclination of the wale so that the optimal anchoring force of the earth anchor can be exercised, can be removed and reused when a retaining wall is dismantled, and allows the stability of the installation of the wale to be increased by a reverse wale hanger.
