The invention relates to a large and medium ground anchor for lifting and hoisting engineering. At present, the large and medium ground anchor is poured by reinforced concrete. After it is used it is discarded and there is large waste. The invention is the renewable ground anchor with steel structure pile load. Pulling force and horizontal resistance of pile are used to take the place of gravity and displacement resistance of concrete anchor. In using, multiple piles are pushed into pile holes on the anchor seat one by one. After using, piles are pulled out and returned. There is no any discarding object. The invention is adaptable for all general soil and it is set on rocks compatibly. The upward component force of ground anchor is conquered by screw, which inserts into rocks and the horizontal resistance is conquered by rods, which inserts into rocks. |
