The intelligent discrimination method for pile foundation pore-forming quality according to claim 7, characterized in that: the detection terminal also comprises a pressure sensor arranged at the bottom of the ultrasonic detector, and the position of the pressure sensor is lower than that of the ultrasonic sensor arranged at the bottom of the ultrasonic detector;
in step S1, the main control unit uses the received pressure signal sent by the pressure sensor as a signal for the ultrasonic detector to reach the pile foundation hole, and then performs the next operation.
