Definitions

  • the present invention relates to surface drainage and in particular, linear 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.
  • AU733361 discloses a surface drainage system comprising a channel in a surface, the channel having outlets to a drain pipe positioned below the channel.
  • US5,307,590 discloses a plant production system utilising slotted drain pipes between slab components to provide a soaking bed.
  • the present invention provides a drainage channel section according to claim 1.
  • the pipe portion and slot portion are provided as separate components.
  • the transverse opening or at least one of the transverse openings is divided by a wall that is substantially incompressible in the lateral direction, into which a material in which the channel section is embedded in use can extend from either side of the channel section to form a structural prop member by way of face-to-face contact.
  • the channel section has a generally triangular form.
  • FIGS 1 and 3 show a plastics drainage channel section 1 in accordance with an embodiment of the present invention.
  • the drainage channel could of course be made from any suitable rigid or resilient material such as steel for instance.
  • the channel section comprises a generally triangular pipe portion 2 having open end faces, although the pipe portion may be provided with a different shape. At their upper ends, the side walls of the pipe portion are spaced from one another to define an elongate, open slot 3 to be located in a horizontal surface plane in use. Water entering the slot passes into the pipe portion 2.
  • a series of tubular cross-members 4 extend through the pipe portion across its width to form a series of passages that extend from one side of the channel section to the other. When installed, concrete bridges extend through these passages to support the concrete surface slab over the channel section.
  • a filter member (not shown) can be mounted within the slot 3, supported by the tubular cross-members 4.
  • the filter may take the form of a mesh material. This filter serves to prevent large solid objects entering the inlet former. It is designed to be removable through the slot at the upper end of the former for cleaning.
  • the channel section may be moulded from medium density polyethylene (MDPE). It may be provided in differing cross sectional sizes depending on the capacity required.
  • MDPE medium density polyethylene
  • the channel section is preferably constructed having a mean size of 900mm deep by 600mm wide. A smaller system may be provided with a size of 600mm x 400mm.
  • the channel section is preferably a two metre standard length, although it may be convenient to also provide shorter or longer lengths (e.g. 1 metre lengths). However, if the site where the system is to be located has sufficient handling capabilities, longer lengths of channel section may be used.
  • the channel section is formed in one piece.
  • the component count for a drainage installation is minimised.
  • This approach can also create a stiffer integrated monolithic structure. Alignment problems during installation are also avoided.
  • the invention also encompasses a fabricated two (or more) part construction.
  • an upper portion of the channel section that forms the slot inlet 3 may be formed separately from the lower pipe portion 2.
  • Figures 2 and 4 illustrates an alternative embodiment in which the tubular cross-members 4 are interrupted by a vertical plate 5, creating two opposed, blind lateral openings having face to face contact, one opening to either side of the former.
  • Figures 5 and 6 show a channel section having a rolled edge 6, 6' which may be used when the section is for use with asphalt and/or block surfacing materials.
  • a series of these sections be interconnected to form a high capacity drainage system. Any suitable form of connection between the open end faces of adjacent sections may be employed.
  • a water seal (not shown) is fitted between end faces of adjacent channel sections to form a seal.
  • This seal may be made of rubber, neoprene or ethylene propylene diene monomer (EPDM) which is highly resistant to water.
  • EPDM ethylene propylene diene monomer
  • the seal is preferably a donut section with a hollow centre to allow give good compressibility to absorb tolerance variations on length.
  • an alternative connector between the open end faces of adjacent sections can be provided by a sleeve 7 which bears against the outer surface of the sections.
  • the sleeve which may be capable of forming a water seal, can be positioned over the join between adjacent sections.
  • the sleeve can be moveable along the outer surface of the channel section, such that when two section ends abut each other, the sleeve can be moved along one section until it is positioned over the join.
  • the sleeve could be located at one end of a first section such that a second section is pushed into the sleeve until it abuts the first section, leaving the sleeve positioned over the join.
  • the channel section is provided with a foot (not shown) which can engage the ground, this would ease installation.
  • the foot may be formed separately from the section and bear against its outer surface in much the same way as the alternative connector.
  • the foot may have a flanged construction which spreads out laterally with respect to the channel section. The foot provides support to the section while being positioned in the surface to be drained during installation. Also the foot provides support against up-thrust as the wet concrete is introduced to secure the section in place.
  • the alternative connector is adapted to provide the functionality of the sleeve and the foot in one integral component. Additionally, as the alternative connector bears against the outer surface of the channel section, it may be used in combination with the donut sectioned seal.
  • a drainage system employing the channel sections described above can be installed in the following manner. First a trench is dug in the ground of the area to be drained. Multiple channel sections are laid into the trench, butted one against the other and secured together, preferably with the use of the sleeve mentioned above. The channel sections are held in position in the trench (e.g. using straps and the foot integral with the sleeve) and then embedded in concrete (or other surfacing material). The channel sections serve as a liner in use. The load is borne by a reinforced top slab incorporated during installation of the system, including the concrete bridges that extend through the channel sections.
  • the concrete will be poured in at least two stages to avoid excessive up-thrust due to the buoyancy of the channel produced by the wet concrete during the first pour.
  • reinforcement may be positioned around the channel and loose bars and/or fabric is passed through the lateral passages prior to the concrete being poured.
  • a blanking rod (not shown) may be placed in the slot inlet to prevent ingress of wet concrete into the channel during installation.
  • the blanking rod substantially fills the slot inlet in order to reinforce the inlet during installation.
  • the concrete or the like surrounds the inlet during installation of the system, the concrete applies lateral forces on the outer walls of the inlet which act to close or minimize its width.
  • Providing the blanking rod is made from a sufficiently robust material(s), it can fill the inlet to provide support to the inner walls in resisting the lateral forces which are applied to the outer walls. As the concrete sets the rod can be moved away from the inlet since the lateral forces applied by the concrete will no longer act to minimize or close the slot.
  • a heel guard grating structure may be mounted on the slot.
  • a galvanised or stainless steel slotted rail can be applied above the plastic slot.
  • This rail can be fitted like a saddle over the slot and secured using suitable fixings to maintain mechanical alignment.
  • Such a rail is better able to withstand the demands placed on the surface where aircraft towing tractors can achieve wheel loads in excess of 30 tonnes or where jet-blast may aggravate the paved surface.
