Thanks Otto .. Upon further investigation I found just what I expected ..

I welded together 4" box tubing (six and one half feet tall) to fit snugly over the drain pipe and designed a saddle to fit uniformly over the pipe diameter ..



placed it over the pipe and drove it down with the excavator .. backfilled with clay and placed some large flat rock on top .. it won't come up again .. guaranteed .. Ill take some pics of the finished product on Friday morning .. weather permitting

No such thing as a problem .. just opportunities
