Title: EXPANDABLE GROUND REINFORCEMENT APPARATUS USED IN REMOVABLE SOIL-NAILING METHOD
Abstract:
The present invention relates to an expandable ground reinforcement apparatus used in removable soil-nailing, comprising: a first anchoring member having a plurality of rotatable blade members; and a second anchoring member which is anchored along with the first anchoring member while pushing and spreading the blade members by means of the rotation of steel wires. As the plurality of blade members are unfolded in the ground, the blade members are firmly fixed into the ground, and thus there is an effect in which the first anchoring member and the second anchoring member can be stably anchored into the ground.
