Ground improvement / lateral injection of ultra-high pressure water for ground cutting 'CJG method'
Using ultra-high pressure water, air, and curing materials, a cylindrical improvement body with a maximum height of 2 meters is created. It can accommodate construction depths of over 25 meters and is applicable to a wide range of soil types.
The CJG method involves cutting the ground by injecting ultra-high-pressure water mixed with air laterally from a rotating triple-pipe rod, while simultaneously filling with hardening material and discharging slime to the surface, thereby creating a cylindrical improved body. 【Applications】 ● Improvement of the base during excavation / Pre-embedded underground beams ● Prevention of subsidence for newly constructed roads ● Shield launch and arrival protection ● Reinforcement of tunnels ● Water stop reinforcement for gaps in earth retention work 【Features】 ● Capable of construction depths of over 25 meters and applicable to a wide range of soil types. ● Can achieve a maximum improvement diameter of 2.0 meters with a small drilling diameter. ● Excellent adhesion to earth retention walls and structures. ● Compact working equipment, offering excellent workability. ● Uses cement-based hardening materials, providing superior durability.
