A Pain in the Drain hurts my Brain!

On the weekend my uncle David was helping dig the pond out line and he found a lump of concrete. He decided that the right thing to do was to hit it with a pickaxe. Now under that lump of concrete was a drain pipe and the pickaxe smashed it into smithereens. Now we have a broken drain pipe and we need to fix it. I got a foil tray, three rock's and one big bag of sand to protect the drain pipe and let the water still run through the drain pipe.
