PURPOSE: A permanent anchor assembly having press-type rotary wings is provided to generate uniform bearing pressure by allowing rotary wings to uniformly touch the ground. CONSTITUTION: A permanent anchor assembly having press-type rotary wings comprises an anchor body and a tension bar. The anchor body is inserted into a borehole formed on the ground and has multiple rotary wings. The rotary wings have pressing blocks having saw-toothed protrusions and are pressed to the inner wall of the borehole. The tension bar is connected to the anchor body, and the front end is tensed and fixed to the inlet of the borehole. |
