PURPOSE:To obtain a strong stay anchor by a method in which a housing plate, an upper plate, and a resistance plate are integrally driven into the ground by means of a driving pipe, and the resistance plate is expanded under the ground. CONSTITUTION:A housing plate A, an upper plate B, and a resistance plate C are integrally inserted into a driving pipe 24 having a core metal 26 inside, and they are driven to a predetermined depth by striking the core metal 26 by a bar hammer. Then, the driving pipe 24 is struck to expand each resistance plate 16 toward both sides. After the completion of the driving work, the driving pipe 24 is drawn out, and a stay is connected to a pulling bar 14 exposed to the ground's surface and tensed. |
