Drainage channel and associated method

Abstract

An elongate drainage channel capable of receiving runoff from an athletic surface is provided which includes a bottom wall and a pair of sidewalls extending upwardly from the opposed sides of the bottom wall. The drainage channel also includes a projection extending transversely outwardly from the exterior of at least one of the sidewalls and spaced at a predetermined distance below the open top for defining a height to which a subsurface layer is applied adjacent to the drainage channel. The projection is also fracturable from the sidewall so as to act as a mechanical fuse to prevent vibratory or tamping machinery from damaging the drainage channel. In another embodiment of the invention, an elongate channel section is provided which has a bottom surface which includes end portions which are shaped as generally planar reference surfaces. The shaped reference surfaces are generally coplanar with each other and are spaced at a predetermined distance below the open top of the channel for supporting the opposed ends of the channel section in a properly aligned position. The present invention also includes a mold for making drainage channel sections having aligned reference surfaces and associated methods for molding the drainage channel sections and for installing the drainage channel.
