With a big hydraulically operated drive... Think giant portable drill

Which is why they use a machine to install them.
It takes a LOT of torque to drive them in, when the soil is hard.
Consider this.. a 5 HP hydraulic motor (which is about the size of a
softball) can push harder for longer than you can hanging on a big
piece of pipe. (Humans being a sort of 1/4HP driver)
