20090047075 | Modular Block Connecting Techniques - One embodiment of a system of the present disclosure can be implemented as follows. A plurality of wall blocks are stacked to form at least a portion of a retaining wall, each wall block having an interior face, an exterior face; a top surface, and a bottom surface. The system further includes retaining means for securing at least one reinforcement member between stacked wall blocks, the retaining means including a pair of reinforcement member retaining bars that are positioned within a slot crossing the transverse length of the top surface of at least one wall block. A first of the retaining means secures the at least one reinforcement member against the bottom of the slot and a second of the retaining means secures the first retaining members against the side of the slot, such that the at least one reinforcement member is additionally secured between the pair of retaining means. Other systems and methods are also provided. | 02-19-2009 |
20090196695 | Modular Block Connecting Techniques - One embodiment of a system of the present disclosure can be implemented as follows. A plurality of wall blocks are stacked to form at least a portion of a retaining wall, each wall block having an interior face, an exterior face; a top surface, and a bottom surface. The system further includes retaining means for securing at least one reinforcement member between stacked wall blocks. The retaining means includes a pair of retaining bars that are positioned within a slot crossing the transverse length of the top surface of at least one wall block. Each retaining bar has at least front, base, and side faces. The reinforcement member is secured between the front faces of the retaining bars through wedging action produced by force being applied to the base face of the second one of the retaining bars. Other systems and methods are also provided. | 08-06-2009 |
20110020070 | Anchored Cantilever Using Modular Block - A modular block wall system is provided. In one embodiment, among others, the system comprises a modular block wall adjacent to earth material, the wall exhibiting an elevational angle; a first elongated member passing through the wall along the angle, the first elongated member secured at a bottom end and secured at a top end to the wall; and a second elongated member coupled, directly or indirectly, to the top end of the first elongated member and passing generally vertically downwardly into and secured in the earth material. | 01-27-2011 |
20110318100 | Precast Wall System - Disclosed herein are various embodiments of systems related to modular earth retaining wall systems. In one embodiment, among others, a precast retaining wall block configured for assembly into a retaining wall includes a front face portion, a web portion extending outwardly from a rear surface of the front face portion, and aligning elements. The web portion includes a vertical center portion and left and right protrusions extending outwardly from the lower sides of the vertical center portion. The left and right protrusions may be substantially triangular. The aligning elements extend downwardly from a bottom surface of the left and right protrusions for locking the precast retaining wall block to the vertical center portion associated with an underlying precast retaining wall block associated with an underlying row. | 12-29-2011 |

20140169875 | PRECAST WALL SYSTEM - Disclosed herein are various embodiments of systems related to modular earth retaining wall systems. In one embodiment, among others, a precast retaining wall block configured for assembly into a retaining wall includes a front face portion, a web portion extending outwardly from a rear surface of the front face portion, a rear panel portion, and a geogrid material wrapped around at least a portion of the rear panel portion and extending outwardly from the rear panel portion. | 06-19-2014 |
20140234025 | PRECAST LEVELING SEGMENT BELOW A TRAFFIC BARRIER ATOP AN EARTH RETAINING WALL SYTEM - 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. | 08-21-2014 |
20150337509 | PRECAST TRAFFIC BARRIER ATOP RETAINING WALL SYSTEM - Disclosed herein is an embodiment of a roadside barrier to sit on top of a retaining wall to provide impact resistance to vehicular traffic. The precast concrete traffic barrier unit is designed to have a counterweight from soil backfill on the horizontal stem portion of the precast unit that acts to resist overturning pressures from vehicle impact on the precast traffic barrier portion which extends above the roadway surface. The horizontal stem is an exemplary designed triangular in shape to capture more of the backfill soil than typically what soil backfill rest directly above the horizontal stem or counterweight portion. Therefore, the triangular horizontal stem with its arching effect between adjacent units will allow more of the soil backfill to resist impact loading and reduce the amount of concrete needed to provide adequate vehicle restraint protection. An alignment seat locks the traffic barrier unit to the retaining wall below. | 11-26-2015 |
