Definitions

  • the present invention relates to drainage blocks, and in particular to drainage blocks for use in urban settings. Further, the present invention also relates to a drainage block for use in dikes.
  • a drainage block is known from publication US2012/0255624A1 , which discloses a drainage body comprising a base unit and a top unit. The base unit and the top unit are connected via frustoconic or frustopyramidal spacers.
  • such drainage blocks are not suitable for use as pavement in an urban setting, as the top unit is formed as a hollow mesh containing many openings, which openings pose a hazard for pedestrians and cyclists and other users of a pavement in an urban setting. Further, partly due to said openings, such blocks do not meet government regulations for pavements.
  • Other drainage blocks are known, for example from NL1039139C , WO2011/108931A1 , JP2002004242A and WO2016/159775A1 .
  • CN105780726A discloses a block for building a dyke.
  • the present invention seeks to provide a drainage block for dikes as a road pavement with drainage and water buffering properties.
  • the present invention also seeks to provide drainage blocks that can be used in urban areas as pavement with drainage and water buffering properties.
  • a strip drainage block comprising a slab, a base, and a plurality of stems connecting said slab and base, wherein each of the plurality of stems has a cross-sectional area that is smaller than the smallest or minimum cross-sectional areas of the slab and the base, wherein the slab and the base each comprise two longitudinal faces, each comprising a plurality of spacing projections.
  • the plurality of stems comprise any number of stems, for example, it may comprise at least two stems. Alternatively, the plurality of stems may comprise at least three stems. Preferably, the plurality of stems may comprise at least four to five stems. This advantageously reduces the time required for assembly of a drainage block pavement. In particular, a block (or half block) with five, or at least five, stems is stronger and is easier to manufacture.
  • each of the plurality of stems of the strip drainage block has a circular cross-section (cross-section herein is defined as contained in a horizontal plane(s) perpendicular to its central longitudinal axis) throughout its extension, and the diameter is greater towards the base and towards the slab, thereby defining a curved surface between the slab and the base.
  • cross-section herein is defined as contained in a horizontal plane(s) perpendicular to its central longitudinal axis
  • the diameter is greater towards the base and towards the slab, thereby defining a curved surface between the slab and the base.
  • each of the plurality of stems of the strip drainage block has an oval cross-section (cross-section herein defined as contained in a horizontal plane(s) perpendicular to its central longitudinal axis) throughout its extension, the oval cross-section having a maximum dimension, and wherein said maximum dimension is greater towards the base and towards the slab, thereby defining a curved surface between the slab and the base.
  • a curved shape directs the loads, which are applied on the slab, in an effective way. This is because the pressures on the block are distributed in a way that as much as material can be saved, while maintaining material in the areas where the pressures are higher.
  • each of the plurality of stems has a rectangular cross-section (cross-section herein is defined as contained in a horizontal plane(s) perpendicular to its central longitudinal axis) throughout its extension, the rectangular cross-section having a maximum length, and wherein the maximum length is greater towards the base and towards the slab, thereby defining a curved surface between the slab and the base.
  • a curved shape directs the loads, which are applied on the slab, in an effective way. This is because the pressures on the block are distributed in a way that as much as material can be saved, while maintaining material in the areas where the pressures are higher.
  • two of the plurality of stems are outer stems defining two flat, lateral ends of the block, which outer stems comprise a semi-circular, a semi-oval, or a half-rectangle cross-section (depending on the type of strip drainage block as disclosed above as defined by the cross-sectional area of the plurality of stems).
  • semi-circular and semi-oval cross-section it is meant herein a half-circle cross-section and a half-oval cross-section.
  • half-rectangle cross-section it is meant herein that the outer stem cross-sectional area is substantially half of the cross-section area of a stem that is not an outer stem.
  • the block may be comprised of two half blocks, as described in claim 10.
  • the corresponding outer stem may have a wedge-shaped cross-section (corresponding to half of a half-circle), or a quarter oval cross-section, or a quarter-rectangle cross-section, depending on the type of strip drainage block (as defined by the cross-sectional area of the plurality of stems).
  • the lateral ends of a drainage block comprising external stems may be characterized by the claimed flat surfaces which provide a surface for connecting an adjoining a strip drainage block. The lateral ends are preferably flat so that a more stable connection is achieved between two adjoining strip drainage blocks.
  • the plurality of spacing projections define recesses along the slab and the base.
  • the term recesses is used herein to refer to those portions of the slab and base which do not contain a spacing projection, that is, those portions are recessed with respect to the spacing projections.
  • Each of the plurality of spacing projections may have a length that is equal to, or smaller than, the diameter or maximum length of the smallest cross-section of each of the plurality of stems.
  • each of the plurality of spacing projections may have a length that is defined as a ratio of the length of the longitudinal faces of base and slab, for example, each spacing projection may have a length that is 15% of the length of the longitudinal faces of the slab or base.
  • Each of the plurality of spacing projections may have a depth (or thickness) of, for example, 3 mm, with respect to said recesses on the base and slab.
  • the depth or thickness may be larger or smaller depending on the desired size of the drainage gap or spacing. A larger gap increases the drainage rate.
  • each of the plurality of spacing projections is aligned with one of the plurality of stems.
  • the spacing projections may be arranged so that they are not aligned with the stems.
  • they may be intercalated with the stems.
  • the number of spacing projections may relate to the number of stems, for example there are preferably two spacing projections per stem in a strip drainage block provided as whole, and one spacing projection per stem in a strip drainage block provided as a half block. This provides adequate ability to space adjoining blocks.
  • the drainage blocks according to the invention are made of concrete, including geopolymer concrete. Manufacturing the blocks (and half-blocks) out of concrete makes for a stronger block, and in particular makes for a block that can be used as pavement without the need for a top or cover layer (such as drainage sand or other such top layers). When the drainage blocks are used as a fundament/substructure they can be covered with a much less thick top or cover layer than would be necessary in the case of the known blocks, because of the strength of the block according to the invention. Other materials for making the blocks and half-blocks may also be used, such as baked clay or plastics.
  • the invention may consist of a drainage half block comprising a half slab, a half stem, and a half base, and one flat surface.
  • Two such half blocks are intended to be arranged adjacent to each other along their respective flat surfaces, so that the half blocks are symmetrical with respect to a central longitudinal plane of the drainage block.
  • one whole drainage block is formed by joining two half drainage blocks.
  • joining it is meant herein two half blocks being arranged next to each other, along their flat surfaces, either with or without an adhesive such as cement.
  • the half blocks are adjoined without the use of adhesives.
  • a method for manufacturing drainage blocks according to the above description comprising the step of forming the drainage block using a mold.
  • This facilitates manufacturing of the blocks.
  • a mold would thus be provided conforming to the physical and dimensional aspects described herein, which mold is filled with the material of choice for forming the drainage block.
  • the drainage block is formed by adjoining (as defined above) two half blocks, the half blocks being formed by using molds.
