PURPOSE: A nailing device is provided to prevent soil and water contamination by forming a cap, a rod, a coupler, and a spacer member using a wood material. CONSTITUTION: A nailing device comprises an anchorage, rods(13), spacer members(14), and couplers(15). The anchorage is inserted into a borehole and is composed of a front end part and a cap. The front end part is coupled to a screw(13a) formed on the end of the rod. The cap presses the inner wall of the borehole. The rods supply shearing force to a cut slope. The spacer members are inserted into the rods to locate the rods at the center of the borehole. The couplers connect the rods to each other. |
