摘要： Various embodiments of an adjustable mold are disclosed for forming a precast concrete top panel for a modular earth retaining wall, for example but not limited to, a modular mechanically stabilized earth (MSE) retaining wall. The adjustable mold has a support base with a top surface, bottom surface, and surrounding periphery. A plurality of rails is mounted to the support base and upstand generally perpendicular from the support base. The rails are collectively attached together to form a closed lateral side boundary with an open top designed to receive liquified concrete. The support base and rails are designed to form sides of the precast concrete top panel. The rails can be adjusted to change a geometric shape associated with the closed lateral boundary in order to enable production of different top panels having different lateral boundaries, and therefore geometries.

摘要： Various embodiments of an adjustable mold and method for making precast concrete traffic barrier panels with different geometries are disclosed. The panels are used for creating a continuous traffic barrier by placing the panels in a contiguous side-by-side arrangement adjacent a roadway atop a modular earth retaining wall. Each traffic barrier panel has a body with at least front, back, top, bottom, left, and right sides. The mold body has a plurality of walls that define an interior chamber, a door opening to the interior chamber, and a concrete inlet to the interior chamber. The door is designed to be installed on and to be uninstalled from the mold body to respectively close and open the door opening. The door has left side and right side forming panels that are designed to define respectively a left side two-dimensional geometry and a right side two-dimensional geometry of the left and right sides respectively of a traffic barrier panel to be made. The left side and right side two-dimensional geometries are changeable by interchanging the door with differently oriented forming panels or by adjusting two-dimensional orientations of each of the left side and right side forming panels on the existing door. The interior chamber of the mold body in combination with an interior side of the door define an outer surface geometry of the front, back, top, bottom, left, and right sides of the traffic barrier panel to be made.

摘要： Various embodiments of a mechanically stabilized earth (MSE) retaining wall that employ, for reinforcement, round rods with spaced pullout inhibiting structures (for example, round planar disks) are disclosed. The MSE retaining wall has at least one concrete panel. The panel has a generally planar body with a frontside, a backside, and a surrounding peripheral edge. The MSE retaining wall has at least one round, steel rod, the rod having a generally cylindrical elongated body with first and second ends. The first end is attached to the panel, and the elongated body and second end reside within backfill soil against the backside of the panel. The MSE retaining wall further includes at least one steel, pullout inhibiting structure residing along the elongated body of the rod. The pullout inhibiting structure has a body with a surface region that spans in a transverse radial direction from the elongated body of the rod. The rod passes through the body of the pullout inhibiting structure.

摘要： 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).

摘要： Disclosed herein are embodiments of a roadside barrier segment to sit on top of a retaining wall to provide impact resistance to vehicular traffic. Concrete traffic barriers are pre-cast in a controlled manufacturing environment then transported as a modular precast concrete segment to the jobsite and installed interlocking directly on top of an earth retaining wall. The precast concrete segment is designed to have a counterweight from soil backfill on a stem of the precast segment that resists overturning pressures from vehicle impact on the traffic barrier segment that extends above the roadway surface. The stem may be triangular in shape to capture more of the backfill soil. A vertical node may be placed on one side of the segment and a receiving channel on the opposite side of the segment to allow the interaction of adjacent segments to share impact loads from motor vehicles.

摘要： Disclosed are embodiments of a mechanically stabilized earth (MSE) retaining wall that employs one or more reinforcement rods and that can be produced with inexpensive, widely available parts. A concrete panel is provided. A steel connector is provided with a loop and first and second stems. The loop is secured within the concrete panel. The first and second stems are secured to and extend in a linear manner outwardly from the loop. Each of the stems has a circular aperture, which are aligned. A steel reinforcement rod is provided within backfill soil. A steel threaded attachment rod is secured to and extends perpendicular from the reinforcement rod. The attachment rod also extends through the circular apertures of the connector. A screw nut is threaded on the attachment rod to thereby secure together the stems and the reinforcement rod.
