Expanding the scope and lineup! Ground reinforcement work using soil-cement columns.
The "Shinbi Method" is a ground reinforcement technique that constructs soil cement columns by excavating and mixing the ground while discharging a slurry of cement-based solidifying material, and utilizes a thin-walled steel pipe with joints embedded at the center as a ground reinforcement body. The excavation and mixing device of this method is equipped with multiple vertical protrusions on the anti-rotation wings and the upper and lower mixing wings to enhance the mixing performance of the cement-based solidifying material slurry and the ground. By using this excavation and mixing device, it enables construction at low axial rotation speeds and high velocities, while significantly improving the quality of the modified body. 【Features】 ■ Low cost ■ Reduced residual soil ■ High strength ■ High bearing capacity *For more details, please refer to the PDF document or feel free to contact us.
