RJP method
It is also possible to create a fan-shaped improvement body (90° to 270°) using a shaking method!
The "RJP Method" is a ground improvement technique that creates cylindrical improved bodies with a diameter of 2.0 to 3.5 meters in the ground by injecting ultra-high-pressure water jet fluid (Aqua Jet) and air jet fluid, as well as ultra-high-pressure curing material jet fluid (Abrasive Jet) and air jet fluid, through a two-stage injection system using a merging method from a monitor attached to the tip of a multi-pipe rod, while rotating and pulling up. 【Features】 ■ By using a new type of ultra-high-pressure slurry pump that discharges 100 L/min of curing material at a regular pressure of 40 MPa, large cross-section improvements can be made across all ground types. ■ The improvement cross-section can be freely selected due to the oscillation mechanism. ■ Strength adjustments can be made according to the improvement purpose. ■ High quality. ■ Cost-effective. *For more details, please feel free to contact us.
