This is a high-pressure jet mixing method in which a large flow of cement slurry is injected at high pressure from multiple nozzles positioned at the tip of the mixing blades. The direction of injection can be controlled in order to form fan-shaped or rectangular improvement columns. Greater freedom in forming improvement bodies allows improvement directly under existing structures and improvement that can be limited in scale as required, for more effective and more economical groundwork.
