Title:
構造物の腐食環境測定方法、腐食環境測定システム、及び腐食環境測定結果を利用した補修計画策定方法と点検計画策定方法
Document Type and Number:
Japanese Patent JP6944092
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a corrosive environment measurement method and a corrosive environment measurement system which allow a corrosion rate of a structure installed outdoors to be quantitatively and continuously recognized, and to provide a repair plan formulation method, the repair plan allowing repair to be performed at optimal timing in accordance with a degree of deterioration and an inspection plan formulation method, the inspection plan allowing a structure to be inspected at optimal timing in accordance with the progress of corrosion and deterioration.SOLUTION: A sensor is arranged on a measurement object structure, the sensor having an inspection surface on which a pair of electrodes made of a material correlated to the measurement object structure with respect to corrosion resistance are spaced, and the change over time of impedance is measured at an arbitrary frequency within a frequency range allowing separation of resistance relating to ion conductivity of moisture stuck to the inspection surface and resistance of charge migration on surfaces of the electrodes.SELECTED DRAWING: Figure 1
