JSG method / CJG method
Core methods of ultra-high pressure jet grouting! Jet grout "JSG method" "CJG method"
The jet grouting method is a technique that uses ultra-high-pressure jet fluids to cut into the ground and improve the soil. There are two types of jet grouting methods: the "JSG method," which applies pressure to the curing material while excavating the soil and simultaneously mixes the soil with the curing material to create a cylindrical solidified body, and the "column jet method," which cuts the soil with ultra-high-pressure water, discharges the slurry to the surface while filling it with curing material, also creating a cylindrical solidified body. These methods can accommodate soil improvement under various geological conditions, depths, and other circumstances. 【Features】 ■ Reliable and certain construction is possible ■ A wide range of improvements that are not affected by the target soil type ■ High adhesion construction is possible ■ Large-diameter soil improvement can be achieved with small holes, allowing for closer construction to buried objects ■ Appropriate improvement strength can be set according to the improvement purpose ■ Economical and safe materials ■ Versatile mechanisms and compact equipment *For more details, please feel free to contact us.
