Drainage system, apparatus, and method

摘要

Embodiments of the invention provide a drainage system for draining surface liquids from a first surface adjacent to one side of a drainage channel and for providing a transition from the first surface on one side of the drainage channel to a synthetic turf surface or other thick surface material on the other side of the drainage channel.

主权项

1. A drainage apparatus for providing a transition from a first surface to a second surface, the apparatus comprising:
a drainage channel positioned between the first surface and the second surface, wherein the first surface and the second surface are separate from the drainage channel; and a grate for covering said drainage channel, said grate having one or more openings structured to allow a liquid to pass therethrough and into said drainage channel, wherein said grate comprises a first horizontally planar portion and a second horizontally planar portion and a generally vertical third portion extending between said first horizontally planar portion and said second horizontally planar portion, said grate being structured so that said first horizontally planar portion of said grate is positioned at a first level substantially flush with the first surface, and so that said second horizontally planar portion of said grate is positioned at a second level substantially flush with the second surface, and wherein said second level is displaced vertically from and lower than said first level.
