Definitions

  • the invention relates to an apparatus and method for remediation of drains by agitation of drain material, such as disclosed in US 5,203,099 .
  • a common method of draining water, such as rainwater, away from a surface or structure is the use of French drains, which comprise a trench, filled with material such as gravel and stones. Surface water runs into the drain and seeps down through the drain material. The water is therefore directed away from the area surrounding the drain.
  • Such drains are commonly used for the drainage of carriageways, where a drain trench is provided along an edge of the carriageway. Surface water from the carriageway is guided into the drain and seeps down through the drain material. The water is therefore directed away from carriageway, thus reducing the risk of flooding of the carriageway.
  • Drains installed along carriageways are typically replaced every 10 years. However, in between replacements, the performance of the drains can be compromised. This is mainly due to clogging of the material used to fill the drain. If this is not corrected, surface water can collect on the carriageway, which has the potential for causing accidents.
  • US 5,199,195 discloses an excavating device for scraping away high shoulder material on road sides.
  • This material is usually formed on the roadside by rainwater, wind and vegetation erosion.
  • the material is on the roadside and may constitute an obstruction and therefore requires removal.
  • the excavating device comprises cutting means to cut the roadside material and material directing means to direct the cut material away from the roadside.
  • the cutting means is provided by blades and teeth for cutting the roadside material and the material directing means is provided by conveyor blades for conveying the material after it is cut.
  • the roadside material may be directed away from the roadside, e.g. towards a drainage ditch or windrowed to be picked up by a loader.
  • the excavating device is not used in a drain and does not remediate a drain.
  • a drain remediation tool comprising a housing providing an aperture, a rotatable drum at least partially disposed within the housing, a drive shaft attached to the drum and adapted to be attached to drive apparatus for rotation of the drum and a plurality of teeth attached to the drum and protruding therefrom through the aperture of the housing, which, on rotation of the drum, sequentially penetrate material in a drain causing agitation of the material to at least partially release clogging of the material and remediation of the drain, wherein the plurality of teeth comprise a first single tooth provided on a first strip along the cylindrical drum, a second single tooth provided on a second strip along the cylindrical drum and six pairs of teeth provided on third to eighth strips along the cylindrical drum and the first and second single teeth are provided on the first and second strips at positions approximately midway along each strip, for each of the third to eighth strips the pair of teeth are spaced along the strip, for the third, fourth and fifth strips each pair of teeth are offset along the cylindrical drum to provide teeth along the length of the
  • agitation of material of a drain can significantly improve the drain's performance.
  • the agitation has been found to at least partially release clogging of the material in the drain trench which allows the drain to work more freely and thereby remediates the drain.
  • the plurality of teeth may be each substantially in the shape of a triangle, particularly a right-angled triangle.
  • the teeth may have a width of approximately 40mm.
  • the teeth may have a length of approximately 165mm. Agitation of the material of the drain is therefore to a depth in the trench of at least approximately 165mm, which has been found to provide sufficient declogging of the drain material to remediate the drain.
  • the plurality of teeth may be arranged on the drum in a manner to carry some of the material of the drain over the drum.
  • the plurality of teeth may be arranged along and around the cylindrical drum.
  • the plurality of teeth may comprise two or more teeth provided on each of a plurality of strips along the cylindrical drum. For each strip the two or more teeth may be spaced along the strip. For a pair of adjacent strips the two or more teeth on a first strip may be offset along the cylindrical drum from the two or more teeth on a second strip.
  • the plurality of teeth may additionally comprise a single tooth provided on at least one strip along the cylindrical drum.
  • the single tooth may be provided on the at least one strip at a position approximately midway along the strip.
  • the plurality of strips along the cylindrical drum may be spaced around the cylindrical drum.
  • the plurality of strips may be spaced at substantially equal intervals around the cylindrical drum.
  • the plurality of teeth comprise a first single tooth provided on a first strip along the cylindrical drum, a second single tooth provided on a second strip along the cylindrical drum and six pairs of teeth provided on third to eighth strips along the cylindrical drum.
  • the first and second strips are spaced around the cylindrical drum at an interval of approximately 180 degrees.
  • the third, fourth and fifth strips are spaced around a first side of the cylindrical drum at approximately equal intervals between the first and second strips.
  • the sixth, seventh and eighth strips are spaced around a second side of the cylindrical drum at approximately equal intervals between the first and second strips.
  • the first and second single teeth are provided on the first and second strips at positions approximately midway along each strip. For each of the third to eighth strips the pair of teeth are spaced along the strip.
  • each pair of teeth are offset along the cylindrical drum to provide teeth along the length of the cylindrical drum.
  • each pair of teeth are offset along the cylindrical drum to provide teeth along the length of the cylindrical drum.
  • the housing may comprise an approximate partial cylinder with closed ends.
  • the aperture may be provided in a wall of the partial cylinder.
  • the housing may be provided with a levelling plate which acts to at least partially level the material of the drain after agitation.
  • the housing may be provided with an attachment device adapted to attach to a machine for supporting the drain remediation tool in position over the drain in use.
  • the drive shaft may protrude through a further aperture in the housing for attachment to the drive apparatus.
  • a method of remediating a drain comprising causing agitation of material in the drain using a drain remediation tool of the first aspect of the invention.
  • the drain remediation tool 1 comprises a housing 3, a rotatable drum 5, a drive shaft 7 and a plurality of teeth 9.
  • the housing 3 comprises an approximate partial cylinder 11 with closed ends provided by first and second end plates 13.
  • the partial cylinder 11 provides an aperture 15.
  • the housing 3 further comprises a levelling plate 17 and an attachment device 19 adapted to connect to a machine in use.
  • the rotatable drum 5 is substantially cylindrical and is disposed within the housing 3, as shown.
  • the drive shaft 7 is attached to the drum 5.
  • the drive shaft 7 protrudes through a further aperture in the housing 3, as shown, and is attached to a drive apparatus (not shown) for rotation of the drum 5.
  • the drive apparatus comprises a gearbox and a motor (not shown).
  • the plurality of teeth 9 are attached to the drum 5 and protrude therefrom, as shown, so that they project through the aperture 15 in the wall of the partial cylinder 11 of the housing 3.
  • the teeth 9 are substantially in the shape of a right-angled triangle, with, in this embodiment, a width of approximately 40mm and a length of approximately 165mm.
  • the plurality of teeth 9 are arranged along and around the cylindrical drum 5 in a manner to carry some of the material of the drain over the drum 5.
  • the plurality of teeth 9 comprise a first single tooth provided on a first strip along the cylindrical drum 5, a second single tooth provided on a second strip along the cylindrical drum 5 and six pairs of teeth provided on third to eighth strips along the cylindrical drum 5.
  • the first and second strips are spaced around the cylindrical drum 5 at an interval of approximately 180 degrees.
  • the third, fourth and fifth strips are spaced around a first side of the cylindrical drum 5 at approximately equal intervals between the first and second strips.
  • the sixth, seventh and eighth strips are spaced around a second side of the cylindrical drum 5 at approximately equal intervals between the first and second strips.
  • the first and second single teeth are provided on the first and second strips at positions approximately midway along each strip, i.e. midway along the cylindrical drum 5.
  • the pair of teeth are spaced along the strip at positions approximately 300mm apart.
  • each pair of teeth are offset by approximately 85mm along the cylindrical drum 5 to provide teeth along the length of the cylindrical drum 5, as shown.
  • each pair of teeth is offset by approximately 85mm along the cylindrical drum 5 to provide teeth along the length of the cylindrical drum 5, as shown.
  • the drain remediation tool 1 is attached to a machine 21 for use.
  • the machine is a tracked vehicle, but other vehicles or machines could be used for operation of the tool.
  • the attachment device 19 of the housing 3 attaches the tool 1 to an arm 23 of the tracked vehicle 21.
  • the drive apparatus (not shown) is attached to a power supply (not shown) of the vehicle 21 for rotation of the drum 5.
  • the drain remediation tool 1 is supported in position over a drain such that the aperture 15 of the housing 3 is placed adjacent a trench of the drain and the plurality of teeth 9 protrude through the aperture 15 into material in the drain trench.
  • the tool 1 is moved along the drain by the vehicle 21.
