Summary:PURPOSE: A dismantling/eliminating type soil nailing method is provided to remove and recover a steel bar for reinforcement easily. CONSTITUTION: The dismantling/eliminating type soil nailing method comprises the steps of: pre-manufacturing a soil nailing device attached with a plastic pipe for inputting a detonating cord along an anchor steel bar(10) for reinforcement; sheeting the excavation wall surface by installing an earth anchor completed by interposing the soil nailing device to a hole bored on the excavation wall surface, forming hardened grout(12) unified with the soil nailing device by grouting into the hole, then fixing an end of the anchor steel bar(10) exposed outward; at the point of refilling around the excavated wall surface, inputting a detonating cord into the plastic pipe, then deflagrating the detonating cord to crush the hardened grout(12) for separation and breakaway of the hardened grout(12) and the anchor steel bar(10), and drawing and recovering the anchor steel bar(10) to the ground.
