1. Ray the rod with multiple wings under the ground to create the anchoring force
2. When using the 29mm high-intensity reinforcing bars, the tensile force is 20 tons at maximum anchoring force.
3. Depending on the nature of the soil , it could be economic to make a small punching length.
4. Expect the tie back effect
5. Increase the friction force with the pressurized grouting
