Definitions

  • This invention relates to a gully arrangement which may form, for example, part of a drainage system.
  • the drainage system includes a plurality of gullies which are conventionally provided at the side of a road or in another convenient location to receive rain water and transfer the same to the sewer. Such gullies are generally referred to as road gullies.
  • a gully arrangement comprising: a housing having an inlet at an upper end thereof, a reservoir in a lower region thereof, and an outlet in a side of the housing at a level between the reservoir and the inlet; and a valve provided in an upper region of the housing and adapted to close the inlet in the event liquid in the housing rises substantially to the level of the valve.
  • the housing may be provided with a continuous inwardly-extending lip for sealing with the valve.
  • the valve may be adapted to seal with a lower surface of the lip.
  • a peripheral region of the valve may engage with the lip.
  • the valve may comprise a flap valve pivotably mounted along one edge thereof.
  • the specific gravity of the valve may be less than 1. That is, the valve may be made of a material having a specific gravity less than 1 and/or the valve may be provided with a float, for example along a free edge thereof.
  • the valve may be provided with reinforcing ribs, for example extending in two transverse directions.
  • the valve In an open configuration of the inlet, the valve may be received in a recess provided in a wall of the housing.
  • the outlet may extend in use in an upwardly inclined direction to form a trap.
  • Figure 1 is a cross-sectional view of one embodiment of a gully according to the present invention in a first configuration
  • Figure 2 is a cross-sectional view of the gully of Figure 1 in a second
  • the gully shown in Figures 1 and 2 is similar to a conventional road gully, but includes non-return valve means to prevent backflow in the event of flood conditions. Excess water and/or sewage can then be directed to a location set aside to receive the overflow in flood conditions.
  • the illustrated gully according to the present invention includes a housing 1 which is conveniently of substantially square or rectangular
  • the housing is formed with a reservoir 3 in a lower region thereof and with a conduit system in an upper region thereof.
  • An upper outlet conduit 5 is normally closed by a removable stopper (not shown), while a lower outlet conduit 7 exits the housing at a lower level than the upper conduit 5 and extends in an upwardly inclined direction to communicate with the upper conduit 5 in a lateral protrusion 9 of the housing 1 , the removable stopper and the rising conduit 7 giving rise to a baffle forming a trap between the reservoir and the conduits.
  • the trap prevents the escape of odours from the remainder of the drainage system (not shown). Not all gullies require a trap.
  • the housing 1 may be made, for example, of cast concrete or glass-filled polypropylene or polyethylene.
  • the housing is formed with a continuous inwardly-extending lip 15 around the region of the upper edge thereof so as to form an inlet opening 17, the lower surface of the lip providing a sealing surface.
  • the lip may have a width of, for example, about 25 mm.
  • a flap valve 19 is pivotably mounted along an edge thereof, for example by means of a suitable pivot pin and is movable between first and second positions.
  • the flap valve 19 is configured to close the opening 17 in the first position and is configured substantially not to obstruct the opening in the second position. To this end, in the second position the flap valve 19 is in a substantially vertical position and is received in a lateral recess formed in a side of the housing 1.
  • the flap valve 19 engages with the lower sealing surface of the lip 15 so as to prevent flow out of the opening 17 of the housing.
  • the flap valve 19 may be made of a plastics material, such as acrylonitrile-butadiene-styrene (ABS) or polypropylene.
  • the flap valve 19 has an overall specific gravity less than 1 such that it floats on the liquid as it rises within the housing 1. That is, the flap valve may be made of a material, such as a plastics material, having a specific gravity less than 1 and/or the flap valve may be provided with a float 23, for example along a free edge thereof, in order to cause the valve to rise as the liquid level within the housing rises.
  • the flap valve may be provided with reinforcing ribs, for example in two transverse directions in order to reinforce the valve and to reduce flexing thereof.

Abstract

Dispositif de bouche d'égout comportant une enceinte (1) dotée d'une entrée (17) à son extrémité supérieure, d'un réservoir (3) dans sa région inférieure et d'une sortie (7) dans un côté de l'enceinte à un niveau situé entre le réservoir et l'entrée. Une vanne (19) est placée dans une région supérieure de l'enceinte et est prévue pour fermer l'entrée dans le cas où le liquide présent dans l'enceinte s'élèverait sensiblement jusqu'au niveau de la vanne.
