  • Patent number: 6565289
    Abstract: A self-connecting, reinforced retaining wall is provided comprised of precast, stacked concrete block masonry units stabilized with reinforcing members which extend from the masonry units at selected intervals into the adjacent reinforced soil to form a mechanically stabilized earthen wall construction. The reinforcement members are generally in the form of horizontally oriented “U”-shaped members which extend from within the adjacent soil bank, to and through voids of the masonry units, thereby providing self-connecting means thereat, and thence returning into the soil bank, forming a stabilized, retained and reinforced soil embankment. Suitable reinforcements may include metallic grids, geotextile and geogrid sheets, and other similar reinforcement means. Concrete masonry units especially adapted for use in the aforesaid self-connecting soil reinforced retaining walls are also provided.
