How does a cement pile driver work?
That's the gravity of the object itself
It's like the principle that we hammer a nail. Use gravity to press down.
The pile driver has hydraulic and stampingThe hydraulic type is to clamp the pile with the clamp, use the weight of the weight of the counterweight block to push down the pile through the push of the hydraulic piston, press down a certain distance, the clamp loosens the piston, retract again, clamp again, press down againThe ramjet is on the top of the pile by blasting to oil burning up the pile under heavy piston reaction force
