The bottom of the pit is filled with mineral soil and is compacted as a foundation of a retaining wall. A protective filter made from draining mineral soil is installed on the foothill of the scarp, where the protective filter is surrounded by draining geotextile. The geogrid is placed on the surface of the regressed scarp and then anchored to the soil of the scarp by tensile ropes. A rigid support, such as a crib (grillage), is created on the protective filter and batter piles are driven under the rigid support. Then the retaining wall is constructed, consisting of layers of compacted soil that are surrounded by draining geotextile. The retaining wall is covered by erosion control mats, anchored to the draining geotextile of the soil layers of the retaining wall.

  • Patent number: 9057171
    Abstract: A block for a retaining wall having a front face forming part of a visible side of a retaining wall, and a support face which supports at least one similar overlying block. The support face is angled with respect to the front face and traversed by a through opening which defines an internal abutment surface placed at a first predetermined distance from the front face. A reference element protrudes from the support face at a second predetermined distance from the front face, in order to abut, in use, against the at least one internal abutment surface of the similar overlying block and thus prevent the displacement thereof in only one of two directions which are transverse to the front face. The reference element includes a flattened engagement portion. An elongate slot is provided on the support face to receive the corresponding flattened engagement portion.

    Abstract: Example may provide a system for constructing a mechanically stabilized earth structure. The system may include a soil reinforcing element having a plurality of transverse wires coupled with a pair of longitudinal wires and a wire facing having a bend formed therein to form a horizontal element and a vertical facing. The pair of longitudinal wires may have lead ends that may converge and may be coupled with a connection stud having a first end and a second end. The first end is coupled with the lead ends and the second end comprises a connector bent with respect to the first end. At least the connection stud and the pair of longitudinal wires may be coplanar. The connector is coupled with at least one vertical wire of the vertical facing such that the soil reinforcing element swivels in a horizontal plane about the at least one vertical wire.

    Abstract: A soil reinforcing element for a mechanically stabilized earth structure may include two wires spaced apart from each other (e.g., substantially parallel to each other). Each wire may include at least two wire strands twisted about one another. A flexible outer member may enclose the two wires, may extend between the two wires, and may couple the two wires with each other. The flexible outer member may maintain the two wires spaced apart from each other, and may define at least one aperture between the at least two wires. The flexible outer member may have a protrusion extending along the length thereof. In another exemplary embodiment, a plurality of transverse wires may be coupled to the two parallel wires.

  • Patent number: 9011048
    Abstract: A method for constructing a mechanically stabilized earthen embankment has the steps of constructing a wall facing element, and determining a plane of maximum force and a zone of maximum force in the earthen embankment to be formed. A plurality of elongate soil reinforcement elements are bent to form semi-extensible bent segments, but such that proximal and distal portions remain substantially straight and inextensible. The elongate soil reinforcement elements are positioned such that the semi-extensible region is within the zone of maximum force, and the proximal ends are connected to the wall facing element. Fill soil is added to build the earthen embankment, and the process is repeated until the earthen embankment is formed.

  • Patent number: 8992131
    Abstract: Disclosed is an economical and effective way of producing a modular retaining wall, using only blocks which in and of themselves are of insufficient thickness to function as retaining wall blocks. The modular wall includes backer blocks and facing blocks which are connected by connectors in a back to back, spaced apart arrangement, thereby forming a hollow retaining wall. The hollow wall can be filled with loose filler material to increase the mass and retaining capacity of the wall. Further disclosed are wall components and a wall kit for a modular retaining wall. A double sided decorative wall is also disclosed. The modular wall system allows for the construction of retaining walls and freestanding, double sided, decorative walls forming both straight and curved walls.
