The "Columnar Improvement Method" involves injecting cement milk into stable ground, compacting the soil into columnar shapes using machinery, and then constructing a foundation on top of it. Columns made of a cement-based solidifying agent (soil improvement cement) mixed with soil, referred to as columns, are created within the ground. By selecting the appropriate soil hardening agent, this method can accommodate improvement work for various soil types, including clay and sand. 【Process】 ■ Using specialized construction machinery, excavate to the planned depth while injecting the cement-based solidifying agent. ■ Reverse the construction machinery to mix the soil and cement-based solidifying agent. ■ Raise and lower the pit of the construction machinery to mix the entire area. ■ Completion is achieved once the material is fully solidified. *For more details, please download the PDF or feel free to contact us.
