Soil nail-Earth anchor Hybrid Structure and Method for Slope Reinforcement

摘要

The present invention relates to a ground reinforcement structure which is formed by combining an earth anchor and a soil nailing to one perforated hole and a ground reinforcement method thereof. More specifically, the ground reinforcement structure applies the load onto the ground with the initial tension of a strand of the ground anchor in advance to resist a part of the ground deformation load. Additionally, the present invention resists the remaining ground load with the strand of the ground anchor and the soil nail reinforcing member at the same time. The present invention also presses the grouting and the ground surface by using the recovery force of the elastic damper inserted and installed onto the inlet of the perforated hole to widen the reinforcement range and improve reinforcement effect to widen the perforation space.
