How deep can that go? Can you fit yourself and shovel in the ring to go deeper? Is there any danger of collapse?

- schobi 3y agoI went to 4.5m - the rings did not slide easily any more as we paused for a year. If you work on it right away, you can go much further I went with an inner diameter of 1m, this is fine for a small shovel, a pump, a small jackhammer. Concrete rings are used all the time in road construction work. I don't see a risk of collapse with those when stacking carefully. Even if one ring were to get a crack, where should it go? I felt safe in this regard
