Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an estimation method of strength characteristics of soil cement capable of estimating strength characteristics from particle size of the soil, and an estimation device, a quality management method of a foot protection part when constructing pile, and a quality management unit.SOLUTION: Disclosed method is a method for estimating strength characteristics of a soil cement constituted of a mixture of a cement material, a soil material and water. The method includes: a step S1 in which granularity characteristics of the soil material is calculated; a step S2 in which a correlation relationship between the elastic wave speed of the soil cement and the strength characteristics based on the calculated granularity characteristics of the soil material; a step S3 in which the elastic wave speed of the soil cement is measured; and a step S4 in which the strength characteristics are estimated corresponding to the measured elastic wave speed from the correlation relationship.SELECTED DRAWING: Figure 1
