Definitions

  • This invention relates generally to concrete blocks used for the prevention of erosion of soil along inclined areas such as highway overpass embankments . More specifically , the present invention relates to the utilization of a matrix o f concrete blocks , each block having passageways or tunnels therethrough through which passes a cable or the like, which, after passing through each block within the matrix system, is anchored into the ground or other supporting surface in order to retain the blocks to prevent the erosion of soil thereabout .
  • Soil erosion prevention blocks and other revetment blocks and structures are well known in the art.
  • Pilaar, Patent No . 2, 597,928, is most pertinent . It discloses a matrix of soil erosion controlling blocks adhered to a porous , flexible mat positioned upon the land or surface where it is desired to control the erosion of soil.
  • Appleton, Patent Nb . 3,903, 702 discloses a revetment structure comprising a system of concrete blocks having vertical passageways therethrough such that a number o f blocks may be positioned adjacent one another to prevent the erosion of soil thereunder while allowing foliage , etc. to grow up through the holes or passageways within the blocks.
  • the present invention is directed to a concrete block for use in the prevention of soil erosion having internal passageways or tunnels through which are passed cables or the like in order to interconnect a matrix of co ⁇ rete blocks in order to more easily transport and position the matrix mat of concrete blocks at the intended location .
  • the block has basically square upper and lower surfaces, and the preferred embodiment has four side surfaces or walls dimensioned such that the height of the block is less than one-half of the length o f a side .
  • the block contains internal passageways from side to side through which pass cables or the like that serve to interconnect a matrix o f blocks to retain same in position. Also , the free ends o f the cables are anchored into the ground or other supporting surface to retain the concrete blocks in position. After anchoring the cables, soil and foliage may be spread over and between the blocks, thereby providing a smooth, reinforced surface for controlling soil erosion.
  • FIG. 1 is an isometric view of the soil erosion prevention block.
  • FIG. 2 is a top view of the soil erosion prevention block showing the internal cable passageways and reinforcing tunnels as dotted lines.
  • FIG. 3 is a front view of a soil erosion prevention block.
  • FIG. 4 is a side view of the soil erosion prevention block.
  • FIG. 5 is an isometric view of a number of soil erosion prevention blocks held together by cables.
  • the soil erosion prevention block is illustrated in its entirety by reference designation 10, and is shown to comprise an upper surface 12, a lower surface 14, front and rear side surfaces 16 and left and right side surfaces 18.
  • the side surfaces are dimensional such that the height of the block 10 is less than one-half of the length o f a side . All surfaces are substantially flat in construction, with the lower surface illustrated as being planar as opposed to the other surface which contain variations in contour. It is to be understood that some of the surfaces may be angled relative to the other surfaces.
  • the block 10 is constructed of concrete because of its cost and availability and because of the function the block is to perform.
  • the block 10 includes a plurality o f first internal passageways or channels 20 passing vertically through the block from the upper surface 12 to the lower surface 14 so as to permit soil to be placed therein and foliage to grow therefrom as an aid in retaining the block in position.
  • the block 10 may include second internal passageways 22 passing through the block and interconnecting opposite side walls 16 and 18, respectively. As shown in FIGS. 3 and 4, these internal passageways 22 are essentially parallel to the lower surface 14 and are at different distances therefrom in order to avoid crossing or meeting internally within the block 10.
  • the second passageways 22 include reinforcing tunnels 24 formed therewith and constructed of a material somewhat stronger than the concrete block. This material may be metal, plastic or other material that is resistant to the chemical effects of concrete. Also included are flared openings at each end of the tunnels 24 at the point where the tunnels join the side surfaces 16 and 18. This flaring aids in inserting a cable or the like into and through the internal passageways 22 when a plurality of blocks 10 is interconnected to form a matrix.
  • the preferred embodiment includes front and rear side surface shoulders 28 and left and right side surface shoulders 30. These shoulders 28 and 30, respectively, are butted against mating shoulders of identical adjacent blocks in order to form a smooth pattern matrix of support blocks. When so positioned, the shoulders 28 and 30 on adjacent blocks form third external passageways 32 between the blocks, shown in FIG. 5, which third passageways function similar to the first internal passageways 20 by allowing the foliage to grow therethrough to aid in retaining the blocks in position.
  • the front and rear side surface shoulders 28 and left and right side surface shoulders 30 include front and rear shoulder tapered portions 34 and left and right shoulder tapered portions 36, respectively.
  • the shoulder tapered portions 34 and 36 form fourth external passageways 50 between the blocks, such fourth passageways also serving to hold soil and foliage therein to aid in preventing the soil from eroding away.
  • the block 10 also includes upper surface recesses 42 which, in the preferred embodiment, communicate with the first internal pasageways 20 so as to provide added space for soil and foliage growth to prevent soil erosion.
  • a plurality of concrete blocks 10 is positioned with front and rear side surface shoulders 28 butting against one another so as to form a continuous line of blocks.
  • a cable, wire, wire rope, synthetic polymer rope or the like 44 is passed through the block second internal passageways 22 and through the reinforcing tunnel 24 of each of the blocks 10.
  • the free ends of the cable or the like 44 are connected in some suitable manner to form closed loops by which the blocks may be picked up and transported about.
  • Multiple rows of concrete blocks 10 may be laid out side by side and multiple cables 44 passed through each second internal passageway 22 and reinforcing tunnel 24 and then connected as above-mentioned.
  • cables 44 are passed through second internal passageways 22 and reinforcing tunnels 24 running crosswise or perpendicular to the passageways 22 containing cables just inserted.
  • the free ends of these cables 44 are then connected to each other so that each cable within the system forms a closed loop.
  • the size and number of blocks 10 within the matrix is dictated by the size and shape of the particular area to be protected from soil erosion, and the size and type of cable used is dictated by the weight and number of blocks used to form the matrix.
  • the particular area desired to be protected from soil erosion is graded or otherwise smoothed over to form a substantially flat, smooth surface 46, preferably with no foliage thereon.
  • the matrix of concrete blocks 10 may then be lifted, transported to the site to be protected and positioned thereon using some form of spreader bar.
  • front and rear side surface shoulders 28 are tapered slightly inwardly to permit a row of blocks 10 to form a slight concave pattern when the blocks are picked up by the cables 44. This feature greatly simplifies handling of the block matrix with a spreader bar.
  • the block matrix is laid in position and the individual blocks 10 repositioned adjacent one another to form a tight matrix of blocks.
  • the cables 44 are then disconnected from each other and may be embedded into the ground or supporting surface 46 in order to retain the block matrix in position. Obviously, not all of the cables 44 need be anchored into the ground. Some may be cut off and a cable stop affixed to the end adjacent the peripheral block in order to hold the blocks tightly together.
  • the shoulder design of the side walls 16 and 18 creates recesses 32 between the blocks which may accommodate cable stops within the block matrix and still permit the blocks 10 to be butted against one another in a tight matrix .
  • dirt may be poured over the matrix and allowed to settle into the various passageways and recesses formed within the blocks and between the blocks , thereby allowing foliage to grow in and between the blocks.
  • dirt After the dirt has been poured over the block matrix , it is graded to form a surface even with the upper surface 12 of the block matrix. Normally, some settling will occur thereafter, requiring that rrore dirt be added at a later time in order to sufficiently cover the upper surface of the blocks and provide sufficient soil for foliage growth.
  • Cables 44 passing through the various second internal passageways 22 o f the block 10 have the added feature of helping to prevent erosion of the soil in the cables within the block recesses and passageways 32, formed by the various side surfaces 28 and 30, provide another element to which grass and other foliage roots may attach themselves to aid in retaining the soil in position between the blocks and within the various block passageways and recesses.
  • the second internal passageways 22 and reinforcing tunnels 24 may be eliminated from the soil erosion block 10 and the block or the matrix of blocks used with a suitable mat 48 of flexible filter cloth or the like positioned between the block and the surface to be protected to aid in preventing the erosion o f the soil.
  • the filter cloth mat 48 is positioned upon the preferably foliage-free , graded surface so as to conform therewith and prevent soil erosion.
  • erosion prevention blocks 10 are positioned thereupon and adj acent one another to form a tight matrix. Thereafter, the soil may be poured o ver the matrix, allowed to settle and more soil added at a later time as set out hereinabove.
  • the filter cloth mat 48 permits water drainage therethrough while simultaneously providing a surface to which the roots of foliage growing between the various block matrix passageways may attach themselves to aid in retaining the soil in position between the blocks and various block passageways and recesses.
