We too have poor rocky soil. I was able to achieve some success in putting
an 8' copper pipe into the ground. Here's how I did it. I have a 6 foot steel
rod/pry bar that has a point on the end. It has straight smooth sides.
I picked a time after it had been raining for a few days, so the clay was
slightly softer than concrete. I just started lifting it up and jamming it
down back into the same hole again and again. After a little while, I noticed
that I was making pretty good progress. Eventually, I had the thing to the
point that it would only stick out about 6-8". During the process, I would
occasionally add a little water to soften things up.
Once I couldn't use the pry bar, I took a hammer and put a point on the pipe
by flattening the end and then folding over the corners. Then I started
pounding. However, the end quickly mashed down, so I rummaged around and
found a steel shaft with a shoulder that just fit in/over the pipe. This
worked for a while, but was splitting the pipe. I then rummaged around some
more and found a steel sleeve that fit over the pipe. This bolstered up
the copper pipe enough so that I could use a sledge hammer to drive the thing
in to about 6" from the top.
