Abstract

A drainage support apparatus and culvert drain inlet adapter. In accordance with one embodiment, the drainage support apparatus includes a substantially rigid conduit support member having bottom and lateral containment surfaces and an open channel slot running the length of the conduit support member. The apparatus further includes water-permeable barriers transversely disposed in relative abutment at each of the open-faced longitudinal ends of the conduit support member such that the water-permeable barriers substantially prevent aggregate material contained within the apparatus from passing through the open longitudinal ends of the conduit support member. In an alternate embodiment, a culvert pipe inlet adapter of the present invention includes a frame member having a raised drain orifice, and further includes sheet members extending in a saddle-like manner from each of the two lateral sides of the frame member. The inlet adapter can be fitted lengthwise onto a suitably apertured culvert pipe section in a manner such that the culvert pipe is backfill buried while the drain inlet orifice remains above ground.
