Abstract: A ground anchor device for securing a building foundation and other structures to a ground surface using the subject anchor device. The anchor device is designed to be self advancing when rotated into the ground surface to depths of 10 to 30 feet and greater and to engage and penetrate an underground rock formation for providing greater anchor stability. The device includes a plurality of external hollow pipe sections and a plurality of internal pipe sections. The external pipe sections are joined together with helix couplings. Each helix coupling includes a helix around the exterior surface of the helix coupling. The helice are used for driving the external pipe sections into the ground. The internal pipe sections are coupled together and have a hollow cross section with a lower end of one of the internal pipe sections attached to a rock bit.
