NAILING METHOD USING EXPANSION ANCHOR FOR REINFORCEMENT OF UNSTABLE SLOPE

摘要

PURPOSE: A shape of a nail expansion member and a nailing method for reinforcement of unstable soil slope are provided to improve the frictional resistance effect around reinforcements, the tip bearing effect by a tip expansion body, and the anchoring effects by the tension of reinforcements. CONSTITUTION: A nail expansion member for reinforcement of unstable soil slope comprises an expansion body(10), an outer tube(20) and an inner tube(30). The inner tube is formed of a tensile member. A nailing method for reinforcement of unstable soil slope using the nail expansion member comprises steps of inserting a nail and pulling the tensile member to expand the expansion body to be fixed in a bore hole.
