Abstract

Abstract Ramp apparatus conveying water across a thoroughfare includes a pair of ramp elements spaced apart from each other with a liquid carrying element disposed between them. The ramp elements and the liquid carrying element are secured together as an integral unit, and coupling elements are disposed in opposite ends of the ramp for coupling to hoses, etc. The apparatus is designed to be disposed across the thoroughfare, and accordingly has a relatively low profile for ease of traffic problems as traffic moves over the ramp apparatus and at the same time is able to carry a substantial amount of fluid or liquid, such as water, from one side of the thoroughfare to the other side.
