Definitions

  • This invention relates to blocks for use in permeable pavements and to a pavement comprising a plurality of such blocks.
  • a block suitable for use in permeable pavements having top, bottom and side faces, at least one side face including a flat part, a recessed part and a projecting part, wherein the recessed part is recessed inwards from the flat part of the side face by a distance (d) , the projecting part projects outwards from the flat part of the side face by a distance (D) which is greater than the distance (d) , the projecting part has a curved face curved about an axis transverse to the plane of the top of the block, and the recessed part has a curved face curved about an axis transverse to the plane of the top of the block and matching the curvature of the projecting part.
  • the curved face of the projecting part is of circular cylindrical shape.
  • the engagement of projecting and recessed parts of the faces of adjacent blocks can be arranged to be substantially independent of the relative angles of the blocks, for a limited range of relative angles.
  • the radius of curvature of the projecting part and the recessed part are similar and are preferably the same (and, if different, the radius of curvature of the projecting part is preferably less than that of the recessed part) ; preferably the radius of curvature is in the range of 5 to 30 mm. In an embodiment of the ' invention the radius of curvature is about 10 mm.
  • the angle subtended by the curved face of the projecting part is preferably in the range of 117 to 147 degrees; in an embodiment of the invention the angle subtended is about 132 degrees.
  • the angle subtended by the curved face of the recessed part is preferably in the range of 121 to 151 degrees; in an embodiment of the invention the angle subtended is about 136 degrees.
  • the recessed part and the projecting part are preferably disposed on the side face of the block adjacent to one another. That facilitates the relative positioning of adjacent blocks during laying.
  • each side face includes a flat part, a recessed part and a projecting part.
  • the recessed part and the projecting part on each side face are substantially the same and are spaced apart from one another by substantially the same distance on each side face.
  • the block may be in any of a variety of shapes (e.g. ⁇ L' shaped, octagon shaped, hexagon shaped) , but it is preferred that the block has four side faces and is of generally rectangular shape (when viewed from above) .
  • the block may be square but preferably two opposite side faces are longer than the other two opposite side faces, the longer opposite side faces each having two recessed parts and two projecting parts and the other opposite side faces each having one recessed part and one projecting part.
  • the side faces of the block preferably have 180° rotational symmetry about an axis perpendicular to the top of the block and indeed the block as a whole may have such 180° rotational symmetry.
  • a paving comprising a plurality of blocks, each block being as defined above, the projecting part of a first block engaging in the recessed part of a second block.
  • the projecting part of the second block engages in the recessed part of the first block.

Abstract

L'invention concerne un bloc (1) destiné à une utilisation dans des pavements perméables. Le bloc (1) a des faces supérieure (2), inférieure et latérales (3, 4, 5, 6). Au moins une des faces latérales (3, 4, 5, 6) du bloc (1) comprend une partie plate (7), une partie renfoncée (9) et une partie saillante (8). La partie renfoncée (9) est renfoncée vers l'intérieur d'une distance (d) à partir de la partie plate (7) de la face latérale. La partie saillante (8) fait saillie vers l'extérieur d'une distance (D) à partir de la partie plate (7) de la face latérale. La distance (D) est supérieure à la distance (d). La partie saillante (8) a une face courbe (11), dont l'axe de courbure est transverse au plan de la face supérieure (2) du bloc. La partie renfoncée (9) a aussi une face courbe (13), dont l'axe de courbure est transverse au plan de la face supérieure (2) du bloc et dont la courbure correspond à celle de la partie saillante (8).
