I would clamp a steel bar on the outside and use a heavy duty forged clamp and tighten until straight. you may need some heat. Maybe a 2" square tube with 1/4" wall long enough to go from top of bucket to the bottom of bucket.
I removed a large concrete patio and could not find a reasonable way to get rid of the concrete. My pile was only 40 cubic yards. I hired a guy to dig a hole in a low area on my 5 acres and I buried it. The low spot in my yard is gone the concrete is gone and no more standig water in that...
