Abstract
An improved system for draining bunkers on golf courses and other sports playing areas, and for draining landscaped areas. A receptacle is positioned below the surface for receiving drain water and for discharging the water through an outlet. A perforated pipe water collection system can be attached to the receptacle to direct water to the receptacle interior space. A receptacle cover is removable to permit access to the receptacle interior space. The cover is sufficiently strong to support the overlying weight of people and equipment, and can have apertures for permitting water entry while resisting entry of sand and other solids into the interior space of the receptacle.
Claims28
A drainage box suitable for use below the surface of a sports field or landscaped area, which drainage box comprises:
- a) a container having a top opening and having a size and shape which can be located below the playing surface a sufficient distance to allow play above the drainage box;
- b) the container having at least one support surface associated with the top opening;
- and
- c) a water permeable cover over the top opening and supported by the support surface, the water permeable cover on the support surface having a strength which permits play above the drainage box but which resists entry of solids into the box;
- d) the box having one or more locations in its sides or bottom which can be associated with an exit pipe for drainage of water from the box.
The box of claim 11 in which the cover has a protective support grate located over the envelope of water permeable mesh.
A water permeable support structure for a drainage box comprising a support grate and a water permeable envelope containing the support grate.
A system for draining water from a sports playing field or landscaped area, which system comprises:
- (a) locating a drainage box under the playing field or landscaped area to accept drainage water a sufficient distance below the surface of the playing field or landscaped area to allow activity above the box, the box having a water permeable cover with playing or landscape material over the cover;
- (b) connecting the drainage box to an outlet which directs water outside of the playing field or landscape area, and
- (c) cleaning the box by removing material overlying the cover and the cover, and removing solids collected within the box;
- and then replacing the cover and the overlying material to reform the playing field or landscape area.
A drainage system for a sports playing field, the drainage system comprising a drainage box located below the playing surface of the playing field to accept drainage water, the box being located a sufficient distance below the surface of the playing field to allow play above the box, the drainage box having a water permeable cover for supporting playing material over the cover;
- a drain outlet associated with the box to direct water from the box and the playing field;
- and a water collection system associated with the box to direct water from the playing field into the box;
- the cover of the box being openable to allow cleaning of the box and being replaceable to allow reforming of the playing surface of the playing field.
A drainage system for a landscaped area, the drainage system comprising a drainage box located below the surface of the landscaped area to accept drainage water, the box being located a sufficient distance below the surface of the landscaped area to allow activity above the box, the drainage box having a water permeable cover for supporting landscape material over the cover;
- a drain outlet associated with the box to direct water from the box and the landscape area;
- and a water collection system associated with the box to direct water from the landscape area into the box;
- the cover of the box being openable to allow cleaning of the box and being replaceable to allow reforming of the surface of the landscaped area.
