Facing the soil and utilizing it! The V-JET method enables large diameter construction and high-speed execution.
The "V-JET Method" is a high-pressure injection mixing technique that cuts the ground using ultra-high-pressure spraying of cement-based hardening materials, creating cylindrical improved bodies at high speed. By using a special dedicated monitor with a step counter-injection mechanism, more efficient cutting is possible, achieving faster construction and larger diameter improved bodies. The entire process from drilling to construction is carried out continuously with a single construction machine, allowing for efficient construction with compact equipment. 【Features】 ■ High-speed construction of large-diameter improved bodies ■ Adoption of direct drilling method ■ Reduction of sludge discharge ■ Measures against ground liquefaction ■ Excellent cost-effectiveness For more details, please refer to the catalog or feel free to contact us.
