Ground improvement / A consistent cylindrical diameter is expected for any type of soil with the "X-JET Method."

Cutting with two intersecting jets allows for excellent mixing and stirring, enabling the creation of high-quality modified bodies. It also exhibits excellent adhesion to retaining walls and structures.

The X-JET method involves cutting the ground by horizontally injecting ultra-high-pressure water mixed with air from a rotating triple-pipe rod, while simultaneously filling it with hardening material and discharging slime to the surface, thereby creating a cylindrical improved body of a certain diameter. 【Applications】 ● Improvement of the base during excavation / Pre-embedded underground beams ● Prevention of subsidence in newly constructed roads ● Shield launch and arrival protection ● Reinforcement of tunnels ● Water stop reinforcement for gaps in retaining walls ● Liquefaction countermeasures 【Features】 ● A consistent cylindrical diameter can be expected for any type of soil. ● Three types are set to accommodate construction purposes and conditions: Ø1.5m, Ø2.0m, and Ø2.5m. ● Excellent adhesion to retaining walls and structures. ● Cutting is performed with two intersecting jets, allowing for superior mixing and the creation of high-quality improved bodies. ● Using cement-based hardening materials ensures excellent durability.
