Pile penetration methods can be classified in either dynamic penetration method or static penetration method. Dynamic penetration method inevitably generates excessive noise and vibration due to their reliance on percussive or vibratory energy. On the other hand, static penetration method won’t generate such construction pollution. If reaction force for penetration is derived only from the weight of the piling rig, the rig needs to be massive. It is not a practicable.
In the Press-in Method, piles are installed with static load generated from hydraulic rams. The reaction for the press-in force is derived from extraction resistance of previously driven piles. That is why a small press-in machine can generate greater force by integrated with the Earth. Such compact machines can work under physically restricted work conditions
