Definitions

  • This invention relates to drain constructions of the kind generally used for collecting surface water from roadways, paths or other hard paved surfaces on which water or other liquids tend to collect.
  • open gutters formed by an open channel in the surface to be drained.
  • the channel is often formed in a series of blocks, precast or cast in situ, arranged end-to-end.
  • installation of conventional drainage channels of the above- mentioned kind is expensive, and the use of gratings is also expensive, due to the cost of the actual grating itself and also the cost of seatings or other fixtures in which the grating is located.
  • Patent Specification GB-A-1 441 023 discloses an alternative form of assembly for use in drain construction and of the kind comprising an elongate, generally tubular conduit having, extending along the complete length thereof, an elongate opening which is narrower than the conduit and faces upwardly in use of the assembly, two spaced elongate wall members disposed along opposite sides of the opening and extending away from the opening so as to define between them a slot communicating, through the opening, with the interior of the conduit, and spacing means interconnecting the wall members to maintain them apart.
  • Such an assembly may be installed, in a drain construction, by forming a trench in the ground, locating the assembly within the trench with the slot defined by the wall members facing upwardly and the upper edges of the wall members substantially level with the surface of the ground, and then filling the trench up to ground level around the assembly with a material, e.g. a settable material such as concrete, which is such as to embed and support the assembly.
  • a material e.g. a settable material such as concrete, which is such as to embed and support the assembly.
  • the conduit and wall members are formed from rigid metal and the lower edges of the wall members are permanently secured, for example by bolting or welding, to the edges of the conduit along each side of the elongate opening in the conduit.
  • the permanent attachment of the conduit to the wall members means that the depth of the conduit below the surface of the ground is fixed and determined by the depth of the wall members and cannot be adjusted.
  • the present invention sets out to provide an improved drain assembly of the kind referred to above which is easier and cheaper to manufacture and where the conduit is not permanently secured to the wall members so that the position of the conduit in relation to the wall members, and hence the depth of the conduit below the ground surface, can be adjusted if required.
  • an assembly for use in drain construction and of the kind referred to above is characterised in that the conduit is formed of resiliently flexible material and is attached to the wall members by virtue of the two edges of the conduit, which define the opening therebetween, being engaged with parts of the respective wall members by the resilience of the conduit.
  • Adjustable spacing means may be provided between the elongate wall members.
  • the adjustable spacing means may include spring means, such as a helical compression spring, interconnecting the wall members in a manner tending to urge the wall members apart.
  • the adjustable spacing means may comprise a temperature responsive device connected between the wall members in a manner to adjust the spacing between the wall members in accordance with the ambient temperature.
  • the adjustable spacing means are enclosed in a protective sleeve extending between the wall members.
  • the protective sleeve may comprise two telescoping parts between slide relatively to one another to accommodate relative movement between said wall members.
  • the generally tubular conduit is formed of flexible material, adjustment of the spacing between the wall members is accompanied by corresponding adjustment of the width of the opening in the conduit, said adjustment being permitted by flexure of the walls of the conduit.
  • each wall member may be provided on each wall member a plurality of alternative locations for attachment of the conduit thereto, whereby the depth of the slot provided between the wall members, relative to the conduit, may be adjusted.
  • a location for attachment of the conduit to each wall member may be provided by at least one longitudinally extending groove along the outer surface of the wall member into which grooves are engageable the two edges of the conduit which define the aforesaid opening therein.
  • the conduit may be formed of resiliently flexible plastics material, said edges of the conduit being retained in said grooves by the resilience of the conduit.
  • the conduit may be generally circular in cross-section.
  • the width of the slot defined by said wall members preferably increases as it extends towards the conduit.
  • each wall member remote from the conduit may be provided with an outwardly extending flange, and each outwardly extending flange may be formed, on the surface thereof facing away from the conduit, with spaced grooves extending transversely to, and opening into, the slot defined by the wall members.
  • the bottom walls of said groves are inclined towards the conduit as they extend towards the slot defined between the wall members.
  • a number of the assemblies may be placed end-to-end so that the slots and internal drainage conduits are in communication.
  • Figure 1 is a perspective view of a drain construction arranged in accordance with the present invention
  • Figure 2 is a cross-sectional view of a spring spacer used in the drain construction.
  • the drain construction shown in the drawings includes an assembly comprising two generally angle section wall members 10 and 11 and a resilient conduit tube 12.
  • the members 10 and 11 are preferably made from cast iron or plastics material and are of similar section. Each is provided along its upper edge with a tapering, shorter outwardly extending flange which is formed on its upper surface with spaced tapering grooves 13 to give a castellated effect at the upper edge of a slot defined between the members. This arrangement tends to dissipate energy in the flow of water across the assembly, thus encouraging the water to flow into the slot.
  • the grooves taper outwardly so as to provide, in the base of each groove, a downward sloping surface leading into the slot.
  • each wall member 10 and 11 extend downwardly but slot away from one another towards the lower ends so that the slot is of increasing width.
  • the conduit tube 12 which is made from a resilient material such as, for example, plastics material, is of generally circular configuration but with an upwardly presented longitudinal opening.
  • the edges of the tube which define the opening are engaged in one of the grooves 15 in the respective wall members 10 and 11.
  • the capacity of the drain is adjustable by regulating the depth of the slot and the cross-sectional area of the conduit 12 in relation to the width of the slot between the two members 10 and 11.
  • the tube 12 is conveniently made initially as a complete tube which is split and the two sides separated in order to engage in the grooves 15 in the members 10 and 11 as shown.
  • each spacer comprises a helical compression spring 21, opposite ends of which abut plates 18, 19 on the inner surfaces of the wall members 10, 11 respectively.
  • the spring is located by screws 22, 23 which project through the wall members and into the ends of the spring. It is protected against dirt and debris by two telescopically slidable tubes 16, 17 which surround the spring 21, the ends of the tubes being closed by the plates 18, 19.
  • the spring 21 permits the members 10 and 11 to move towards and away from one another as a result of movement or expansion of the material surrounding the assembly.
  • the spacers may be temperature responsive piston and cylinder units containing fluid which is responsive to temperature change to tend to expand the unit, so as to keep the members 10, 11 apart while allowing some relative movement thereof.
  • the assembly in use is embedded in a body of material, indicated at 24, such as concrete or tarmc or construction material including polymer structures.
  • the material is settable and provides a flat top surface. Any expansion or concentration of this material results in movement of the members 10 and 11 towards or away from one another and this is accommodated by the spring spacers.
  • Keying elements 25 are provided on the sides of the members 10 and 11 to lock them into the settable material 24.
  • the method of making the drain construction comprises assembling the members 10 and 11 and the tube 12 in correct relationship, as shown, the spring spacers being inserted at intervals along the length of the assembly. Further similar assemblies are placed end-to-end to provide a continuous drain. Typically, each assembly may have a length of one metre or longer. Connecting members (not shown) in the form of sleeves surrounding the tube 12 may be fitted to provide a water-tight or substantially water-tight seal beween adjacent lengths of the drain. In this way a complete drain, wich a continuous open slot and a continuous drainage conduit may be simply formed in minimum time.
  • the assemblies are placed in a prepared trench and are suspended by hooks 28 from battens 27 which are long enough to reach datum levels in the surrounding surface.
  • the hooks 28 are adjustable in length, having adjustment nuts engaging threads on the upper ends thereof.
  • the hooked lower ends engage the spring spacers already described.
  • the trench is back-filled with settable material to the required level corresponding to the top surfaces of the flanges of the members 10 and 11.
  • the assembly may be initially below the required level, and the placing of the settable material may be such as to lift the assembly into the correct position so that its top surface lies level with that of the settable material itself.
  • this may be filled with boards or other components which are afterwards removed.
  • bridge pieces are inserted at spaced positions along the length of the slot.
  • This assembly provides a continuous drain which may have a fall from one end to another. Longitudinal and transverse levels are taken into account. Any expansion or contraction of the settable material or its surrounding material as a result of changes in temperature, or other movement, is readily accommodated by movement of the members 10 and 11 under the influence of the spring spacers.
  • the spring or equivalent spacers may be used in other circumstances in bridge or road engineering where expansion is to be accommodated.
