When practicing for cyclocross you can make your own barriers or use some logs dragged out of the woods. Or pick up a portable set from Cross Propz, a small outfit that sells quick setup barriers made of PVC pipe. The company's Lightweight CycloCross Barriers are 17 inches tall and 67 inches wide—an approximate hurdle seen on many races. They set up automatically and pop back into place if run over on a missed leap.
