DEVICE AND METHOD FOR MANUFACTURING HYDRAULIC SOLIDIFICATION MATERIAL LIQUID-SUBSTITUTED COLUMN, AND HYDRAULIC SOLIDIFICATION MATERIAL LIQUID-SUBSTITUTED COLUMN

摘要

PROBLEM TO BE SOLVED: To enhance vertical bearing capacity of a hydraulic solidification material liquid-substituted column and realize a high-strength and high-quality hydraulic solidification material liquid-substituted column, without significantly changing manufacturing processes thereof.SOLUTION: A discharge port 4 having a diameter from 3 mm to 10 mm is disposed on a drilling rod 1a or a conical head 2, the discharge port being for discharging hydraulic solidification material liquid at a discharge pressure sufficient for drilling or infiltrating into a ground around a hole drilled by the drilling rod 1a.SELECTED DRAWING: Figure 1
