Definitions

  • the present invention relates to surface drainage and in particular, linear and point surface drainage arrangements.
  • Another known form of drainage system employs a substantially continuous linear slot in the drained surface to serve as the inlet. It is recognised that surface drainage systems employing linear slots are more efficient than those drainage arrangements possessing discrete inlets, as in general they provide a greater inlet area and minimise the volume of water (or other liquid) that can wash over the drained surface without being entrained by the inlet.
  • US Patent US6000881 shows a linear drainage system of this type, as does GB-A-2311549 . Both of the systems described in these documents employ a large underground channel which has at its upper side a narrower throat portion defined by two walls extending upwardly to the surface to be drained, where they terminate to form a continuous slot drain in the surface.
  • AU199878635 in the name of John Joseph Creighton discloses a surface drainage system comprised of a shallow channel that forms a gutter in a surface, and which is linked by spigots to a drain pipe embedded in the ground below.
  • the present invention provides an.inlet former for a surface drainage system, the inlet former comprising a longitudinal slot that lies in use in a surface to be drained and a conduit via which liquid can drain in use from the surface through the former, wherein the former comprises one or more transverse openings into which a material in which the former is embedded in use can extend from either side of the former to form a structural bridge member.
  • the cantilevered slabs of the conventional linear drainage systems are no longer present.
  • the load of and on the surface material is borne principally by the bridge members as opposed to the inlet former or any underlying structure associated with the installed drainage system.
  • the present invention provides a discrete inlet former which may, but need not be, used in conjunction with an underground drainage channel.
  • the inlet former may be used, for example, to drain water (or other liquid) from a surface into any other form of underlying, manmade or even natural void.
  • the present invention may be configured to provide a linear surface drainage system.
  • the present invention may be configured to provide a point drainage system.
  • each transverse opening may provide a continuous passage though the former from one side to the other, such that the material in which the former is embedded extends through the opening from one side of the former to the other to form the structural bridge.
  • the structural bridge may be formed by the material in which the former is embedded extending from either side of the former into opposed, blind transverse openings, the openings being separated by a wall that is substantially incompressible in the lateral direction.
  • the structural bridge that bears the load of the surface above is in effect formed from two structural props of the material in which the former is embedded and the separating wall against which they butt by way of face to face contact.
  • the wall is substantially incompressible in the lateral direction, force is transmitted between the two material props without exerting any substantial loading on the inlet former itself or any underlying structure.
  • the inlet former may be provided as a multiple-part assembly, which may for example be assembled on site as it is installed, it is preferably formed as a unitary component that can be shipped and installed without the need for subsequent assembly. It will typically be formed in sections of easily manageable lengths which can be used alone, in combination but spaced apart, or butted against one another to form a substantially continuous slot inlet comprising multiple sections.
  • the easily manageable lengths may consist of section lengths of 1 to 2 metres, however, if the site for the system has sufficient handling capabilities, longer lengths of section may be used.
  • the inlet former may include one or more side inlet openings that allow liquid to drain into the inlet former from one or both of its sides.
  • the inlet former prefferably comprises a filter mounted within the inlet slot to prevent the ingress of large solid objects that might cause a blockage in the inlet former or other elements of a drainage systems with which it is used.
  • the invention also provides a linear surface drainage system comprising an inlet former as set forth above and a longitudinal channel, which in use underlies the inlet former and is in fluid communication with the former in order that fluid can drain through the former into this underlying channel.
  • the invention also provides a point drainage system comprising an inlet former as set forth above and a chamber, which in use underlies the inlet former and is in fluid communication with the former in order that fluid can drain through the former into this underlying chamber.
  • the invention provides a surface drainage installation comprising an inlet former as set forth above installed in a surface to be drained and a void underlying the inlet former into which fluid can drain through the former.
  • the void may be provided by an underlying channel. Alternatively, it may simply be an area intended to catch and store drained liquid for later removal, e.g. by allowing the liquid to leach out from this area. Particularly where there is no channel used, it may be preferred that the void is filled with a high void material (i.e. a structural material having large, interconnecting voids within it).
  • the invention also provides a drainage installation comprising an inlet former as set forth above installed in a surface to be drained at the bottom of a gully in the surface.
  • the gully can be pre-formed or formed on site or otherwise.
  • the installation may be formed at the base of a slip-formed channel located in the surface to be drained.
  • the main structure of the inlet former 1 is provided by two side walls 2, 2', both of which are flanged at top edges and bottom edges to form outwardly extending lips 3, 3', 4, 4' respectively.
  • the walls 2, 2' are spaced laterally from one another and joined by tubular cross-members 5. These tubular elements also form openings that extend through the inlet former from one lateral side to the other.
  • the spaced walls define a longitudinal slot 6 designed, in use, to collect water from a surface in which the inlet former is installed.
  • the lower ends of the walls are spaced further from one another than the upper ends, so that the channel they define flares downwardly. This helps to prevent any solid material that enters through the slot becoming wedged in this channel.
  • This filter serves to prevent large solid objects passing though the inlet former. It is designed to be removable through the slot at the upper end of the former for cleaning.
  • the spaces within the former defined between the walls and the tubular cross-members serve as conduits through which liquid that drains into the slot can pass through the inlet former out of its lower end.
  • Each of the former walls also has a series of side inlet openings 8 spaced along their length, between the tubular cross-members. These allow water to drain into the channel defined by the walls from either side of the inlet former.
  • the walls of the inlet former 1, the tubular cross-members 5 and the filter member 6 may be formed of any of a number of appropriate materials including, for example sheet metal (e.g. steel), cast metal (e.g. iron), any other variety of plastics materials or a combination of these materials.
  • the inlet former may be manufactured as a single section or as a number of separate components to be assembled post-manufacture.
  • each wall of the former may be manufactured as a separate component formed integrally with a portion or complete ones of the tubular cross-members.
  • the filter member 6 will normally be a separate component in order that it can be removed if desired.
  • End caps 9 may be provided to seal the open ends defined by the space between the former walls. These also allow the length or effective length of the former to be adjusted depending on the site requirements.
  • Fig.4 illustrates an alternative embodiment in which the passage through the former 1 provided by the tubular elements 5 may be interrupted by a vertical plate 10, creating two opposed, blind lateral openings having face to face contact, one opening to either side of the former.
  • Fig. 5 shows a former 1 having a rolled edge 11, 11' which may be used when the former is for use with asphalt and/or block surfacing materials.
  • a void is formed (e.g. excavated) in the ground in the area that is to be drained.
  • the void in the ground is lined with a water permeable material, such as a geotextile material, that allows water to pass in a controlled fashion from within the void to the surrounding ground.
  • the void itself is filled with a high void material 12.
  • suitable materials include STORMCELLTM provided by Hydro International plc
  • the inlet former 1 is embedded in the slab with its upper end level with the surface of the slab and its lower end opening into the high void material. In this manner a slot drain is formed in the surface, water draining from the surface through the inlet former into the high void material below.
  • the rainwater When there is, for example, rainfall of high intensity, the rainwater will drain quickly through the slot 6 into the high void material 12 and then, over a period of time, soak away through the geotextile material into the surrounding ground.
  • the geotextile material could be impermeable for deliberate water retention.
  • the inlet former On installation, the inlet former is located above the underground void and secured in place by some suitable means.
  • the broad flanges 2, 2' at the lower end of the former walls can be used to secure the former in place (alternatively, in place of such flanges, a series of broad feet might be provided).
  • the surface slab material 13 e.g. concrete
  • the surface material flows through the tubular cross-members 5 of the inlet former to create structural bridges which serve to support the slab to either side of the inlet former, alleviating loading on the inlet former and the underlying high void material.
  • inlet former of the invention may use an underground drainage channel in place of the high void material.
  • inlet former can be adapted to be secured to an inlet opening of the channel.
  • figs. 8 and 9 illustrate an inlet former 1 in combination with an underlying pipe 14.
  • the pipe is provided with cut outs 15 which can be aligned with the location of the conduits in the former defined between the walls 2, 2' and the tubular cross-members 5 to permit the passage of liquid into the slot and down into the pipe via the conduit.
  • the pipe 14 may be made from any suitable rigid or strengthened material, but preferably is made from corrugated steel, spirally wound steel, a plastic material or concrete.
  • Figs. 10 and 11 also illustrate an inlet former 1 in combination with an underlying pipe 14.
  • the pipe is provided with cut outs 15 which can be aligned with the location of the conduits in the former 1 defined between the walls 2, 2' and tubular cross-members 5 to permit the passage of liquid into the slot and down into the pipe via the conduit.
  • the tubular elements 5 are interrupted by a vertical plate 10, creating two opposed, blind lateral openings having face to face contact, one opening to either side of the former.
