AI Technical Summary
Existing pile-type ground anchors are prone to displacement and looseness under soft soil or poor geological conditions, and unreasonable anchor hole design parameters will also lead to looseness.
A reusable pile-type ground anchor is designed, with multiple limiting rods and adjustment screws in the ground anchor body. The adjustment screw drives the connection ring to lift and lower in the installation groove, and the angle adjustment of the limiting rod is adjusted, so that its bumps are inserted into the soil layer to enhance the anchoring degree of the ground anchor.
Through the angle adjustment of the limit rod and the insertion of the bumps, the ground anchors can be effectively prevented from moving upward, improve their stability in soft soil or poor geological conditions, and the structure can be reused.
