1. Three shafts soil mixing rig has to be used to drill the certain depth according to the design, the multi shaft augers can blended the soil and inject the concrete formula into the bore pile.
2. Each unit of bore pile has to be secant, finally the continuous underground wall can be built.
3. Before the cement setting, the H beam need to be inserted into the soil mixing wall to reinforce the wall.
4. After the cement setting, the soil mixing wall will be continuous, high strength, and water tight underground wall.
5. After finish the complete construction, the H beam can be removed from the continuous wall to use again at the next site or either remains there as the continuous wall to be used.
