Abstract
An anchor 20 is disclosed for supporting an open top drainage channel 40 within a trench. Anchor 20 permits accurate placement and easy adjustment of channel 40 and thereafter permits the entire channel 40 to be embedded in concrete in a single pour. The anchor 20 is embedded within the earth defining the trench and counteracts the natural buoyancy so that channel 40 does not float upwardly in the unhardened concrete.
