On the basis of the principle of the pile machine, this paper points out the synchronous problems between the feeding speed and the motor speed are the main problems to ensure the quality of the pile. In this research and development of the synchronous tracking automatic control system of the screen pile machine, a synchronous tracking calculating method, the structure of the system, the principle of the system and the development of a synchronous automatic control system of the single chip microprocessor are presented. The method can be used to solve the displacement match effectively between the pressurized mechanism and the power unit. The practical operations show that the control system is reliable. By using the system, the screw pile loading capacity is strongly increased and the amount of concrete is saved.
