SOIL PROPERTY MANAGEMENT DEVICE AND SOIL PROPERTY MANAGEMENT METHOD

Japanese Patent JP2023009828

A

To provide a soil property management device and a soil property management method for evaluating properties of soil on a ground while reducing influence of dryness and unevenness of the ground.SOLUTION: A soil property management device 1A of soil E of a ground S compacted in a construction process of earth work includes: a capacitor electrode device 20A which measures a potential between a pair of potential electrodes 22 by bringing a pair of capacitor electrodes 20 as a pair of potential electrodes 21 close to the soil E of the ground S and by bringing the pair of capacitor electrodes 20 as the pair of potential electrodes 22 close to the soil E of the ground S while AC current is flowed through the soil E of the ground S by applying AC voltage between the pair of current electrodes 21; a measurement section 31 which measures electric resistance of the soil E based on the AC current flowed to the soil E by the current electrodes 21 and the potential measured by the potential electrodes 22; and a soil evaluation section 32 which evaluates properties of the soil E of the ground S in which the electric resistance is measured. The capacitor electrodes 20 can be measured only by being brought close to the ground S, and the properties of the soil E of the ground S can be evaluated while reducing influence of dryness and unevenness of the ground S.SELECTED DRAWING: Figure 1
