The invention drilling rod to a drilling apparatus for drilling a ground, passing the drilling force and; As to and to the distal end portion of the drilling rod is pushing rotated by the drilling hammer (Hammer) using air pressure to perform a ground drill, the inner center bit (Central Bit) and drilling bit including a ring bit (Ring Bit) of the outer periphery (drilling bit) as made and, and the drilling bit is to be controlled, and the injection pressure is relaxed towards the drilling bit front of the injection direction of the flushing air, outside of the center bit adjacent the compressed air flushes the air guide hole high pressure to the ring bit within the side and thus the opposite high pressure of the flushing air to be induced to induce be injected between the inner surface of the ring bit toward the outer peripheral part one side of the center bit and to be formed in an oblique direction, through the flushing air guide hole of the ring bit guided to impinge on the side, and further injected sample collide with the inner surface of the ring bit In order to ensure that washing air is injected toward the front surfaces of said central bit, the flushing air injection port is located at the rear than the end portion of the ring bit as formed so as to face the inner surface of the ring bit on the outer periphery side of the center bit so as to provide a soft ground reinforcement front portion of the central bit using a device having features formed to have a level difference so as to position the pocket on the front of the inner side of the ring bit, and this.
