Ground improvement / Construction of large-diameter cylindrical improvement bodies using the 'SUPERJET method'

Create large-diameter cylindrical improved bodies. Four types can be set according to construction purposes and conditions, with maximum effective diameters of Ø2.5m, Ø3.5m, Ø5.0m, and Ø6.0m.

The SUPERJET method involves cutting the ground by horizontally injecting ultra-high-pressure solidifying material accompanied by air from a rotating double-pipe rod, while simultaneously discharging slime to the surface and creating large-diameter cylindrical improvement bodies. 【Applications】 ● Improvement of the base during excavation and pre-placed underground beams ● Prevention of subsidence in newly constructed roads ● Shield launch and arrival protection ● Reinforcement of tunnels ● Strengthening of water-stopping in gaps of retaining walls ● Liquefaction countermeasures 【Features】 ● Capable of accommodating a wide range of soil types. Four types can be set with maximum effective diameters of Ø2.5m, Ø3.5m, Ø5.0m, and Ø6.0m to meet construction purposes and conditions. ● Excellent adhesion to retaining walls and structures. ● Achieves high-speed construction by utilizing powerful energy. ● Uses cement-based solidifying materials, providing excellent durability. ● By cutting the same location twice with one rotation, it allows for good mixing and stirring, resulting in high-quality improvement bodies.
