Abstract
A drainage structure having perforated parallel top and bottom plates separated by spacer members. A web joins adjacent spacer members and has a curved profile such that water spilling over the web does so, at a varying velocity profile to increase oxygenation of the water. This drainage structure can also be filled with good drainage soil and planted with grass to filter and retain water that passes therethrough, with a layer of filter medium below and a water permeable drain below the filter medium, to transport water into the substrate and into a reticulation tank where the water can percolate back into the soil.
Claims6
A drainage structure which is generally flat in nature and is for use mainly in a horizontal or substantially horizontal disposition, and comprises top and bottom plate members which are held apart by spacer members so that the structure is cellular in nature with the cells hydraulically interconnected with each other, the plate members having apertures therein which are disposed so that the apertures in the top plate member are offset relative to the apertures in the bottom plate member, and wherein there are web walls extending between adjacent spacer members at the lower plate member, the web walls forming weirs at their top edges, for water retained by the web walls, wherein the top edges of the web wall are curved, to cause the water spilling over these edges into adjacent cells at a varying velocity profile to increase the oxygenation of the water as it splashes on falling from the weir top edges.
A liquid pervious layer support which is generally flat in nature and is for use mainly in a horizontal or substantially horizontal disposition, and comprises top and bottom plate members which are held apart by spacer members so that the structure is cellular in nature with the cells in communication with each other, the plate members having support areas alternating with apertures in a checkerboard arrangement, the apertures are disposed therein so that the apertures in the top plate member are offset relative to the apertures in the bottom plate member, each support area having an opening therein and wherein there are web walls extending between adjacent spacer members at the lower plate member, the web walls forming weirs at their top edges, for water retained by the web walls, wherein the top edges of the web wall are curved, to cause the water spilling over these edges into adjacent cells at a varying velocity profile to increase the oxygenation of the water as it splashes on falling from the weir top edges.
