Abstract (en)
[origin: WO2018122561A1] The present invention provides a moveable insert (204) that blocks the entrance of the drain (200) to prevent any debris or sediment from entering the drain when there is no rainfall or surface water. Any sediment that does settle on top of the drain will be regularly swept up away, either naturally by the surrounding environment or intentionally, for example, by a road sweeper. As such, there will never be a build-up of sand or dust large enough to move the insert. When there is rainfall or surface water, the weight of any water sitting on top of the insert (204) causes the insert to move to thereby create an opening (207,232) through which the water can flow.
