    Abstract: A retaining wall for supporting and stabilizing cut or fill areas of excavation and a method of constructing a retaining wall. The wall is preferably constructed by applying the concrete pneumatically. The method comprises installing a backing board while the vertical wall is pneumatically constructed. The backing board may be selectively removed after application of concrete. The footing and vertical wall can be constructed monolithically utilizing this method. This method of construction yields a high strength wall with very few construction steps and uses materials efficiently. The flexibility in the design and advantages regarding accessibility, along with needing fewer workers for construction, are also a large benefit.

  • Patent number: 7828498
    Abstract: A block assembly includes integral connection mechanisms specifically designed for incorporation into engineered retaining walls. These connection mechanisms specifically accommodate the use of reinforcing grids in the formation of a retaining wall which, when used, will stabilize the retaining wall and provide additional strength. The connection mechanism is formed prior to fabrication of the block itself, and thus can be integrally incorporated during casting/fabrication of the block itself. The connection mechanism defines a connection slot usable during retaining wall fabrication (by allowing easy connection to the reinforcing grid) while also accommodating holding and lifting of the block assembly. Due to the fabrication method, the configuration of the connection mechanisms inserted into the block can be uniquely designed to provide desired physical coupling once the concrete is hardened.

  • Patent number: 7785042
    Abstract: A double-wall protection levee floodwall has a pair of piles placed into soil at the bank at the edge of a water body or formed by a levee. The piles of the pair are oriented parallel to each other, are spaced apart transversely, and are rigidly connected together by a connector so that when the force of rising water or a water-borne object is applied to a face of one of the piles, a force couple develops that places one of the piles in tension and the other pile of the pair in compression. The distance between the force-coupled piles and the depth of the piles in the soil provide the ability to withstand predetermined transverse forces while conserving materials and space. Fill material, riprap, earthen support, and erosion control matting can improve the function of the double-wall floodwall. Multiple pairs of piles can be longitudinally placed to form a continuous floodwall.

The seawall is formed by a mold that includes a base having a generally parallelepiped configuration and a pair of slightly inclined mold walls for forming the sea-retaining wall of the module. A first embodiment includes a steel mold. A second embodiment includes an aluminum mold having parts that open along hinge lines and which require reinforcement dowels to prevent pressure-induced bulges.

  • Patent number: 7563057
    Abstract: An earthen containment reinforcement system has a plurality of connected panels containing recycled rubber vehicle tire material forming a retaining or barrier wall. The panels are connected by interlocking joints, and secured by a reinforcing cable that traverses the length of the connected panels. For added structural integrity, the reinforcing cable is connected by a plurality of tether cables to a corresponding plurality of anchors that are sunken in the earthen containment. An erosion shield is connected to the top edge of the retaining wall, and extends away from the top of the wall toward a land side of the earthen containment that is opposite the water side. By virtue of their construction from recycled vehicle rubber tire material, the panels are not only impervious to water and burrowing rodents and resistant to erosion, earth tremor, and explosion, but are easy and economical to fabricate and maintain.
