A multipurpose nailing anchor is provided to increase the pullout resistance of a nail and the shear resistance of the ground by a nail by locating a nail to the center of a perforated hole, and to have a space adjusting function and a nail fixing function for locating a nail to the center of a perforated hole using a space adjustment support. A multipurpose nailing anchor used for a nailing method for slope stabilization includes a space adjustment support(30) inserted to a nail(20) having a male thread at the outer circumferential surface to make the nail located in the center of a perforated hole of the ground without eccentricity and equipped with a nut coupled with each nail, a ring having the inside diameter enough to move smoothly, a fixing member attached to the side where the nut and the ring face each other to hinge on one end of an arm member whose another end is hinged on the other end of another arm member to be folded or unfolded correspondingly to the inside diameter of the perforated hole, and a ring attachment nut formed on the side of the ring to couple a full thread bolt(40) to be parallel to the longitudinal direction of the nail, so that many space adjustment supports are unified to be folded or unfolded simultaneously. |
