Definitions

  • the invention relates to drainage channels.
  • Drainage channels are formed from drainage channel sections that are laid end-to-end to form a continuous conduit. They are used to drain surface water and may, for example, be located along the lateral edges of roads or across large open areas.
  • the drainage channel is covered by a lid with water draining through the lid and then flowing along the channel.
  • the water will contain suspended solids and it is important that the shape of the channel is such as to maximize the carriage of the suspended solids by the flowing water and minimize their deposit as sediment within the channels.
  • drainage channel sections can stand in a stable upright position so that they do not have to be held upright while they are being laid end-to-end. It is also desirable that the drainage channel sections can be stacked compactly for transport so minimizing the amount of dead space during transport.
  • a drainage channel section including an interior flow-confining surface comprising an elongate planar floor having parallel spaced side edges and two spaced side walls, each side wall projecting upwardly from a respective side edge of the floor and being formed by an upper wall portion and a planar lower wall portion, each lower wall portion having spaced first and second side edges extending generally parallel to the plane of the floor with the first side edge joined to the associated side edge of the floor, each first wall portion being inclined away from the floor at an angle ⁇ with a width W between the second side edges of the lower wall portions, the width of the floor being between W/1.5 and W/2.5 and the height of each second side edge above the plane of the floor being W 2 sin ⁇ where ⁇ is between 45° and 75°.
  • the drainage channel section is formed, for example, from fibre reinforced concrete.
  • the drainage channel section comprises a generally U-shaped shell 10 and three reinforcing ribs 11.
  • the shell 10 includes an interior flow-confining surface comprising an elongate planar floor 12 having parallel spaced side edges 13. Two spaced side walls 14 project upwardly from respective side edges 13.
  • Each side wall 14 is formed by an upper wall portion 15 and a lower wall portion 16.
  • Each lower wall portion 16 is planar and has first and second spaced side edges 17,18 extending generally parallel to the plane of the floor 12. The first side edge 17 of each lower wall portion 16 is continuous with an associated side edge 13 of the floor 12.
  • Each lower wall portion 16 is inclined away from the floor 12 at an angle ⁇ to the plane of the floor 12 which in the illustrated case is 60°. If the width between the second side edges 18 of the lower wall portion 16 is W, the width of the floor 12 and of each lower wall portion 16 is W / 2 and the height of the second side edges 18 above the plane of the floor 12 is W 2 sin60°.
  • the width of the floor 12 may be between W / 1.5 and W / 2.5 and the height of each second side edge 18 above the plane of the floor 12 may be between W 2 sin45° and W 2 sin75°.
  • the upper wall portions 15 lie in respective planes normal to the plane of the floor 12. The upper wall portions 15 are thus separated by a constant distance equal to W.
  • Each upper wall portion 16 has an upper edge 19 defining an opening to the drainage channel.
  • Each upper edge 19 is formed by an outwardly projecting flange 20 having an upper surface 21 lying in a plane parallel to the floor 12 and formed with a longitudinally extending groove 22.
  • the thickness of the shell 10 is constant around its periphery and along its length.
  • the shell 10 thus has an exterior floor 23, exterior lower wall portions 24 and exterior upper wall portions 25.
  • These exterior parts 23,24,25 are dimensioned and shaped in correspondence with the associated interior portions 12,15,16.
  • the ribs 11 extend around the exterior of the shell 10.
  • One rib 11a is located adjacent to, but not at, a first end of the shell, a second rib 11b is located intermediate the ends of the shell and the third rib 11c is located at a second end of the shell 10.
  • the first rib 11a and the second rib 11b are identical and will be described together.
  • Each rib 11a,11b has side faces 26 that converge as they extend away from the shell 10 with the ends of the side faces being interconnected by an outer surface 27.
  • this outer surface 27 has first portions 27a that overlie respective upper wall portions 18 and are parallel to the upper wall portions 18.
  • lower portions 27b that extend downwardly from the level of the second side edges 18 and are angled inwardly.
  • the angle made by these portions 27b to the plane of the floor 12 is greater than the angle made to the plane of the floor 12 by the associated lower wall portions 16 so that the width of the flange increases in this region.
  • the third rib 11c is similar in many respects to the first and second ribs 11a,11b. Parts common to the third rib 11c, on the one hand, and to the first and second ribs 11a,11b, on the other hand, are given the same reference numerals and are not described in detail.
  • the third rib 11c projects slightly beyond the associated end of the shelf 10. Rather than being angled, the side face 26a of the third rib 11c that is beyond the end of the shell 10 lies in a plane normal to the side edges 13 of the floor 12. There is thus formed between the end face 28 of the shell 10 and the interior edge 29 of the third rib 11c an L-shaped rebate. As will be immediately apparent, this is for accommodating the first end of a second drainage channel section so that the sections laid end-to-end can form a continuous channel.
  • Each rib 11a,11b,11c includes six holes 30 spaced around the rib 11a,11b,11c. Two holes 30 are adjacent respective upper edges 19 of the upper wall portions 15, two holes are adjacent respective second side edges 18 of the lower wall portion 16 and two holes 30 are adjacent the side edges 13 of the floor 12. Each hole 30 of each rib 11a,11b,11c is in register with a hole in each of the other ribs 11a,11b,11c along a line parallel to the plane of the floor 12. Thus, reinforcing bars (not shown) can be passed through a set of registering holes 30 for a purpose to be described below.
  • the holes 30 adjacent the side edges 13 of the floor 12 are of larger diameter than the remaining holes 30. These holes can be used to lift a drainage channel section by use of a mechanical lifting device (not shown).
  • Typical values of W may be between 0.15 metres and 0.6 metres.
  • the upper edge 19 of the upper wall portions 15 may be spaced from the plane of the floor by a height H which is between 0.38 metres and 1.1 metres.
  • the drainage channel sections described above with reference to the drawings are produced by casting. A number of such drainage channel sections can be transported in pairs with one section of each pair being inverted and a side wall 14 of the inverted section inserted between the side walls 14 of the other section. This is made possible by the interior shape of the sections, as described above. This reduces significantly the volume occupied by such sections during transportation and storage.
  • a plurality of sections of the kind described above with reference to the drawings are laid end-to-end in a suitably excavated trench.
  • the first end of one section fits into the rebate at the second end of a succeeding section due to the arrangement of the third rib 11c.
  • the sections are laid at a suitable gradient which, for example, may be 1:1000.
  • Reinforcing rods are inserted through the sets of holes 30.
  • the channels are closed by suitable lids of known kind which rest on the upper surfaces 21 of the flanges 20 and may be located by engaging in the grooves 22.
  • the installation may be as described in our GB-A-2229212.
  • One form of lid suitable for use with the drainage channel sections described above with reference to the drawings is described in our UK Patent Application No.9621056.
  • the presence of the floor 12 and the correspondingly shaped portion of the ribs 11, provide a flat surface on which the drainage channel section can stand when stored during transport and during installation.
  • the drainage channel section thus has a stable upright position.
  • drainage channel sections described above with reference to the drawings can accommodate high flow rates.
  • the mobilization of suspended solids is also assisted by water falling through the lid and into the channel. Since the upper side wall portions 15 are substantially vertical, they have little or no effect in preventing the conversion of the potential energy of the water into kinetic energy. Water reaching the lower wall portions 16 thus has maximum kinetic energy and this can provide a scouring effect to mobilize suspended solid matter for conveyance by the water. This mechanism has maximum effect when flow is subsiding during the falling limb of a storm.
  • the ribs need not be shaped as described above; they could have any suitable shape.
  • the shell 10 need not be of constant thickness around the periphery; the thickness could vary.
  • the lid need not be formed separately from the shell; it could be formed with the shell 10 or fixed firmly to the shell 10 on manufacture.
