Construction method "ef column method"
A new method that uses a core steel pipe at the center of soil-cement columns!
The "ef column method" is a construction technique that achieves superior support strength while reducing costs and environmental impact with a smaller diameter than conventional methods. This method includes the removal of the structure after construction and the restoration of the ground. By creating a core steel pipe at the center of the soil cement column and a solidified material milk layer around its periphery, it aims to integrate the improved body and enhance its compressive strength. Additionally, one of its features is that the removal of the columnar improved body can be easily performed. 【Features】 ■ Significant improvement in support strength due to the use of a core steel pipe ■ Small improvement diameter with high support strength ■ Easy removal of soil cement columns ■ Reduced cement usage, lowering costs and environmental impact ■ Smaller diameter reduces residual improved soil *For more details, please refer to the catalog or feel free to contact us.
