ABSTRACT:
A covering element for covering drainage channels on sports fields provides for good surface drainage with a reduction of the danger of accidents for athletes consists of a section plate, made of aluminum, for example, which rests on shoulder surfaces of the drainage channels, and includes side support walls and water drainage slots arranged in the middle. Injury preventing edge elements are mounted with support ribs and the height of support walls and the thickness of edge elements over the support walls are about equal to the height of the upstanding edges of the drainage channels, so that water can consequently flow off well. The edge elements are made of a rubber of Shore hardness A75, so that no danger of injuries to athletes exists, and the edge elements may be colored white for the track side and green or red for the turf side of the sports field.
