Definitions

  • the invention pertains to retaining walls made of sandbags and to interconnecting members for attaching together sandbags in such walls.
  • Retaining walls are used in a wide variety of civil engineering and landscaping applications, for example to support slopes and embankments for highways, support noise barriers, prevent erosion along waterways, etc.
  • Retaining walls are commonly made having a support face structure made of interconnecting blocks with soil or other fill material placed and com- pacted in back of the wall, and sometimes with sheets of geogrid laid in the fill at various levels, extending back from the wall and attached to it.
  • the invention provides sandbag interconnecting members for connecting sandbags in a retaining wall.
  • the sandbag interconnecting member comprises a generally planar body having at least three projections on its upper side and on its lower side, the projections being capable of protruding into sandbags, the interconnecting member being sized such that two or more interconnecting members can fit in spaced-apart positions on the upper or lower side of a sandbag in a course of sandbags in a retaining wall.
  • the invention further provides a sandbag interconnecting member which comprises a piece of material, for example plastic or fabric, having an upper side and a lower side, both of which can form a detachable bond to a sandbag.
  • the surfaces of the interconnecting member, and the wall of the sandbag or a portion thereof, comprise mating parts of a hook-and-loop fastener device (as velcro) or a similar attachment means.
  • a plurality of loose hooks can be applied between a sandbag interconnecting member and the sandbags, or simply between the sandbags themselves. In the latter case, the mass of loose hooks acts as a sandbag interconnecting member.
  • the invention further provides retaining walls comprising two or more courses of sandbags in which vertically-adjacent courses are attached together by means of the sandbag interconnecting members of the invention.
  • Figure 1 is a top perspective view of one embodiment of a sandbag interconnecting member according to the invention.
  • Figure 2 is a bottom perspective view thereof.
  • Figure 3 is a side elevation view thereof.
  • Figure 4 is a top perspective view of another embodiment of the sandbag interconnecting member.
  • Figure 5 is a top plan view of a course of sandbags in a retaining wall with the interconnecting members in position thereon.
  • Figure 6 is a front sectional view of the first two courses of a retaining wall according to the invention.
  • Figure 7 is a top perspective view of another embodiment of the sandbag 15 interconnecting member.
  • the sandbag interconnecting member 10 comprises a body portion 12, which is a generally planar, solid disk, having three spaced-apart projections 14 on its upper surface 16 and three spaced- apart projections 18 on its lower surface 20.
  • the interconnecting member is preferably about ten to twenty centimeters in diameter. It may be made of plastics or aluminum or other non-corrodible material.
  • Figure 5 shows the use of the sandbag interconnecting members 10 in a retaining wall 36 that is made of sandbags 26 supporting backfill 38 and having a wall face 42.
  • retaining wall as used in this specification in relation to structures made of sandbags includes any array of sandbags that is suitable for the purpose of erosion control (for example along shorelines, riverbanks, etc.), flood control, retaining or stabilizing slopes or embankments, noise barriers, and for similar applications.
  • “fill material” means any material that is suitable for use in bags in the construction of retaining walls, including sand, soil, gravel, dry mix concrete (which hardens after wetting and curing), and mixtures thereof, including fill material with seeds for vegetation.
  • sandbag as used in this specification means a bag containing any "fill material”. For further clarity, the term is not limited to a bag in which the fill material is sand.
  • the sandbag interconnecting members are placed in spaced-apart positions on the upper side of the sandbags 26.
  • Two sandbag interconnecting members 10 are placed on each sandbag 26 in the lower course 30, in spaced- apart positions, preferably between the mid-line and the ends 28 of the bag.
  • One or two sandbag interconnecting members may also be placed under each sandbag in the lower course 30, to better secure the wall 36 to the ground on which it is constructed.
  • the sandbags 26 are positioned so that their ends 28 abut each other in the course 30.
  • a second course 32 of sandbags 26 is placed above the first course, with the upper sandbags in a laterally-staggered arrangement relative to the sandbags in the lower course 30, i.e. so that each sandbag in a course rests on two adjacent sandbags in the adjacent lower course.
  • the projections 14 on the upper side of the sandbag interconnecting member protrude into the sandbags in the upper course, and the weight of such sandbags presses the interconnecting members so that the projections 18 on their lower side protrude into the sandbags of the lower course 30.
  • the projec- tions 14, 18 can be configured to penetrate the sandbags, or, preferably, to simply indent them. In either case, the projections are considered to "protrude” into the sandbags. This attaches together the sandbags in the upper course to those in the lower course.
  • the interconnecting members 10 do not extend across the point of abutment of adjacent sandbags within a given course.
  • the courses of the retaining wall structure typically lie generally horizontally, though they may follow the contour of the ground as required.
  • the courses 30, 32 of the wall are laid one above the other, including further courses laid in the same manner to build a wall of the required height.
  • the slope of the resulting wall face of sandbags may vary from a gradual slope to a substantially vertical one, depending on the particular application.
  • the courses 30, 32 of the wall face are "vertically-adjacent" in the sense that they are generally one above the other, so as to form a wall having a height, though not necessarily, or typically, forming a vertical wall, as a wall having some slope is generally preferred.
  • the sandbag interconnecting member 1OA is substantially the same as the interconnect- ing member 10 of Figs. 1 to 3, but it includes an eyelet 22 on either the upper or lower surface of the body 12.
  • a cord 24 can be inserted through the eyelet.
  • the cord may be made of any suitable and durable material, preferably a strong synthetic non-degradeable material. Plastics materials such as nylon or high-density polyethylene are preferred.
  • eyelet 22 other cord-retaining means such as a hook can be employed.
  • the cord 24 is strung through the eyelets 22 of the sandbag interconnecting members 1OA along a given course of sandbags, and is anchored at its ends to the retaining wall, backfill or adjacent ground, for example by means of spikes. This increases the strength and stability of the retaining wall.
  • the sandbag interconnecting members 40 are pieces of fabric, plastic or other material that have hook fasteners on both sides thereof.
  • the sandbags 26 may comprise a fabric, such as geotextile, to which the hook fasteners can detachably connect (in the manner of fabric hook-and-loop fasteners such as velcro) or the sandbags may have strips of loop fasteners attached to them, to which the hook fasteners of the interconnecting members can connect.
  • the opening of the sandbag may also be provided with velcro strips to hold the bag closed after it is filled with fill material.
  • the sandbags 26 are placed in adjacent courses in the retaining wall 36 so that the interconnecting members 40 attach the sandbags in adjacent courses together.
  • the sandbag interconnecting members 40 may be in the form of strips that are oriented laterally across the face of the sandbag, i.e. perpendicular to the wall face 42, in order to provide the greatest resistance to movement from the pressure of the backfill 38 supported by the wall.
  • different shapes, such as square or circular, or different orientations, of the sandbag interconnecting member may also be used.
