The "OHO Drain Method" is a simultaneous embedding technique that suppresses the discharge of excavated soil to the surface and allows for the installation of drainage material, which becomes a drainage medium upon completion of the drilling, at a specified depth. By embedding drainage material in ground with a high potential for liquefaction, it dissipates the rise and accumulation of excess pore water pressure that occurs during an earthquake, thereby preventing ground liquefaction. It enables dry drilling without the use of drilling water or additives, allowing for a clean construction process. 【Application Examples】 - Liquefaction countermeasures for foundation ground of buildings and underground structures - Liquefaction countermeasures for manholes *For more details, please feel free to contact us.

The High Grip Grout Method is a grouting technique that enhances the prevention of chemical leakage from drilled holes using ground packers, ensures a large source of chemical penetration with special sealing materials, and improves injection efficiency through a centralized management system for chemical injection. *NETIS Registered Technology: CB-180028-A [Ground Packers] Ground packers are designed with a structure that prevents the leakage of filling materials (a double structure of fabric and rubber), which suppresses shrinkage after the expansion of the ground packer and enhances the adhesion between the drilled hole and the ground packer. This prevents the leakage of chemicals from the drilled hole. [Special Sealing Materials] The sealing materials use a special substance that fluidizes when reacting with chemicals, protecting the hole walls during drilling and ensuring a large penetration area during chemical injection. This allows for a reduction in injection pressure and the creation of a large-diameter modified body with a diameter of 2.5 meters. [Injection Management System] The system used in this method can simultaneously manage multiple chemical injection pumps (16 points). This improves the efficiency of injection and achieves cost reduction through shortened processes. *For more details, please refer to the catalog or feel free to contact us.

The "Super Multi-Point DP Method" enables injection at 16 points with a single unit and allows for approximately 100,000 liters of injection per day with two units (32 points), making it a soil purification method. It employs construction management technology using computers and has developed compact, low-noise, and low-vibration construction equipment, making it versatile for various applications. It is capable of injecting various liquids, including solution types, suspension types, bio (nutrients), and Fenton (catalysts and oxidants). 【Features】 - Variable discharge of 1 to 10 liters per minute per point - Injection management system that monitors and controls flow rate and injection pressure - Usable in narrow spaces around existing residential land and structures - Extremely low-noise equipment (except for the generator) For more details, please feel free to contact us.

The "Expacker Method" is a technique developed with a focus on the ability to achieve extensive solidification with a large discharge volume at low injection pressure by permeating from a large columnar space, in contrast to conventional chemical injection methods. It is an injection method based on the principle of columnar permeation layering. Multiple injection outer pipes with several bags and discharge ports are installed in the designated improvement area, and by injecting into the inner pipe, the bags are expanded and anchored to the ground to form packers. Grout is then discharged from the inner pipe into the columnar space between the upper and lower packers, allowing for wide-range permeation and rapid construction of large volumes of soil. [Features] ■ Rapid construction of large volumes of soil ■ Cost-effective ■ High quality ■ Liquefaction prevention ■ High-strength ground improvement For more details, please feel free to contact us.
