Definitions

  • the present invention relates to a gully.
  • the gully comprises a hollow body comprising an inlet for receiving a fluid to be drained, and an outlet for being connected to a drain pipe for draining the fluid.
  • Gullies, or storm drains are used to drain fluids such as rainwater from surfaces on streets, parking lots, footpaths, etc.
  • a gully comprises a gully pot that is usually located below surface level when a gully is installed.
  • a gully usually also comprises a grating located approximately on surface level.
  • Rainwater can enter the pot through an inlet covered by the gutter.
  • a liquid such as rainwater may be filtered inside of the gully pot and then discharged from the gully through an outlet port connected to a drain pipe.
  • the drain pipe may, e.g., lead to the sewer system, a retention and/or infiltration facility, a river, or a lake, etc.
  • gullies Due to harsh environmental conditions, such as heavy vehicles (e.g., trucks, lorries, etc.), construction works, heavy rains, etc., gullies experience vibrations and/or pressures that can compromise the function and/or integrity of the gullies (e.g., fracturing or breaking of the gullies), rendering the gullies ineffective.
  • heavy vehicles e.g., trucks, lorries, etc.
  • construction works heavy rains, etc.
  • gullies experience vibrations and/or pressures that can compromise the function and/or integrity of the gullies (e.g., fracturing or breaking of the gullies), rendering the gullies ineffective.
  • gullies need to be cleaned.
  • debris such as sand and leaves filling up the gully may need to be removed from the gully.
  • a part of the gully, and the outlet, in particular, may become blocked. Therefore, a worker performing maintenance may need to open the gully, e.g., opening the gutter grid/cover lid and also take out removable components (if there are any) from the gully, such as a filter.
  • a removable component such as a filter therefore ideally easily fits through the gully inlet.
  • the worker may then, e.g., suck out debris from the gully using negative air pressure and/or may use a hose to eject pressurized water through the gully (e.g., through the outlet) to wash away blocking substances.
  • a large filter pore size is sufficient to ensure that debris does not block a part of the gully and the outlet.
  • a smaller filter pore size is desirable.
  • gullies of different shapes and sizes may be needed.
  • amphibians e.g., frogs, salamanders, caecilians, etc.
  • rodents fall into gullies and get stuck with no means to exit from the gullies. This is undesirable because they may block part of the gully, such as the outlet, they may be carrying numerous bacteria, viruses, parasites etc. that may be hazardous and infect a person, and importantly because the needless animal deaths are undesirable and may cause harm to the ecosystem.
  • gullies that can provide improved integrity (mechanical strength). Furthermore, there is a need for gullies that can provide filters that can be adapted and adjusted for specific situations and/or locations. Furthermore, there is a need for gullies that can provide a safe and reliable method to remove amphibians and/or animals which have fallen therein. Furthermore, there is a need for gullies that can easily be adjusted for specific situations and/or locations, while ensuring the function and/or integrity of the gullies (e.g., water tightness). Furthermore there is a need for gullies that can easily be produced in a cost-efficient manner for different situations and needs, such as sizes or outlet diameters.
  • the present invention provides a gully comprising a hollow body (103; 203) comprising:
  • the body is a substantially cylindrical hollow body, which may taper over at least part of the body.
  • the body extends longitudinally in the vertical direction as seen during normal installation and use of the gully.
  • the rib structure particularly the cross configuration, provides reinforcement to the gully to withstand vibrations and/or pressures transferred to the gully.
  • the cross configuration has a special technical effect of dividing forces caused by the vibrations and/or pressures into two directions, namely the directions of the pair of ribs forming the cross configuration. Thereby, the integrity or mechanical strength of the gully is improved.
  • the rib structure divides or redirects the forces caused by the vibrations and/or pressures onto the surrounding soil, which the present inventors have found to contribute to preventing an amount of force on the bottom section of the gully that would cause failure of the gully in case forces cannot efficiently be distributed to surrounding soil.
  • rib as used herein means a protrusion, e.g. a fin plate.
  • the expression “a plurality of ribs” does not include corrugations.
  • the expression "forming a cross configuration" as used herein means that the ribs of the first pair or the projections of the trajectories of the ribs of the first pair intersect.
  • the pair of first ribs are such that they are substantially parallel in a zone circumferentially adjacent to a zone in which the ribs or the projections of the rib trajectories intersect. It will be understood by the skilled person in the context of the present disclosure that it is sufficient if the projections of the rib trajectories intersect such that a small interruption of the ribs caused by e.g. a joint between adjacent modular gully body parts is still considered a cross configuration.
  • the pair of first ribs together may form a cross-shaped rib or substantial part thereof, e.g. without the center of the cross-shaped rib.
  • Each leg of the cross-shape is formed by one first rib, or multiple aligned sections of the first rib and the aligned interruptions therebetween, wherein the leg of the first rib intersects with the leg of another first rib.
  • the angle between the intersecting legs is not limited to 90 degrees and can range from 1 to 179 degrees, but is preferably within the range of 60 to 120 degrees, more preferably 70 to 110 degrees, most preferably 80 to 100 degrees, for example about 90 degrees.
  • One pair of first ribs may form a cross configuration at one or more, such as two or more zones on the outer surface of the body.
  • the zones being at a different circumferential position but at the same height of the gully.
  • the two or more cross configurations are preferably regularly distributed around the circumference of the gully.
  • the pair of first ribs forms a cross configuration at two zones on the outer surface of the body which are at a different circumferential position but at the same height of the gully, then they are preferably placed at a 180 degree circumferential distance from each other.
  • the pair of first ribs forms a cross configuration at three zones on the outer surface of the body which are at a different circumferential position but at the same height of the gully, then they are preferably placed at a 120 degree circumferential distance from each other.
  • the pair of first ribs forms a cross configuration at four zones on the outer surface of the body which are at a different circumferential position but at the same height of the gully, then they are preferably placed at a 90 degree circumferential distance from each other.
  • the body comprises a plurality of modular body parts.
  • each rib of said pair of first ribs circumferentially extends along two adjacent (i.e., longitudinally adjacent) modular body parts of the plurality of modular body parts.
  • said cross configuration extends along two adjacent modular body parts of the plurality of modular body parts.
  • the gully comprises at least one modular body part which comprises at least two first ribs which each form part of a different cross configuration, preferably comprises at least two first ribs which each form part of a cross configuration extending along two adjacent modular parts.
  • the gully comprises at least 3 modular body parts, but may comprise more modular body parts, such as 4, 5 or 6. It will be understood that the two first ribs which each form part of a different cross configuration will form a complementary diamond-like configuration at one or more first locations on the outer surface of the body in case the cross configurations of each rib are located at the same circumferential position.
  • the inlet and the outlet are comprised in a top half of the body.
  • the inlet and outlet are preferably in the top modular body part.
  • the body comprises a portion in the top half of the body which tapers inwardly towards the inlet, wherein the inlet is preferably a substantially horizontal opening in the top half of the body, preferably in the top modular body part in case of a modular gully as described herein.
  • the substantially horizontal opening is to be understood as being substantially horizontal during normal installation and use of the gully. In other words, it is substantially parallel to the bottom surface of the gulley in case the gully body is substantially cylindrical.
  • the rib structure comprises a pair of joint ribs circumferentially extending between the pair of first ribs forming a cross configuration.
  • the pair of joint ribs are parallel.
  • the pair of joint ribs comprises a bottom joint rib which is the bottom rib comprised in a first modular body part and a top joint rib which is the top rib comprised in a second modular body part, wherein the first and second modular body parts are adjacent body parts and the first modular body part is stacked on the second modular body part, and wherein preferably the pair of first ribs forming a cross configuration intersect the pair of joint ribs.
  • the distance between ribs at a circumferential location should be construed as the smallest distance between adjacent ribs at the circumferential location.
  • the term "circumferential location” as used in the context of the present invention refers to the location on a circle when a top view (e.g. of the body or parts thereof) is projected onto a plane.
  • the outlet is located at the same circumferential location as a cross configuration.
  • the outlet is located at a first circumferential location between a pair of first ribs which are separated by a first distance D1, wherein the first distance D1 is larger at the first circumferential location than at a second circumferential location (circumferentially) adjacent to the first circumferential location.
  • the gully further comprises an insert selected from an odor lock and/or a filter mounted to the hollow body and extending longitudinally inside the body.
  • an insert selected from an odor lock and/or a filter mounted to the hollow body and extending longitudinally inside the body.
  • an insert to function as an odor lock, it should have an enclosing wall which has a closed portion extending beyond the position of the outlet. In normal conditions, the water level will be below the position of the outlet, and the enclosing wall of the odor lock extends sufficiently far into the gully body such as to be submerged and thereby preventing odor (e.g. sewer odor in case the outlet is connected to the sewers) to escape the gully.
  • odor e.g. sewer odor in case the outlet is connected to the sewers
  • the odor lock typically does not extend further than at most half the length of the gully (typically it extends at least 4 cm below the inner diameter of the outlet, such as 4-15 cm) such that during very dry periods, the water level may still drop below the odor lock.
  • An advantage of employing a filter is that aside from limiting entry of debris into the outlet (and e.g. connected sewer system or infiltration facility), cleaning with a vacuum suction hose can be performed with the filter in place as most debris will be contained within the filter interior.
  • the gully further comprises a filter mounted to the hollow body for filtering the fluid before draining, the filter extending longitudinally inside the body.
  • the body comprises a plurality of modular body parts and the filter comprises a plurality of modular filter parts, wherein the bottom of each modular filter part does not extend beyond the bottom of a respective modular body part in which the modular filter part is located.

  • the filter is modular and the enclosing wall of the top modular part is closed (i.e. free of perforation or pores).
  • the enclosing wall of the filter may be perforated in a top part of the filter such that the filter may have the dual function of filter and aerator.
  • This is desirable in some applications where there is no need for an odor lock (e.g. when the outlet is connected to a rainwater storage and/or infiltration facility) and brings the additional advantage that by including perforations in the top filter part, a significant aeration of system connected to the outlet is achieved. This is an important advantage in case of large amounts of rainfall needing to be absorbed by a rainwater storage and/or infiltration field.
