Title:
METHOD AND DEVICE FOR STEEL MATERIAL POTENTIAL MEASUREMENT
Document Type and Number:
Japanese Patent JP2017125822
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method and a device for efficiently measuring potential of a steel material in a concrete structure embedded with a steel material.SOLUTION: A steel material potential measurement method measures a potential of a steel material 11b embedded in a concrete structure 11 by using a steel material potential measurement device 1. The steel material measurement device 1 includes: a standard contact part 2; a reference electrode unit 3 having a plurality of reference electrodes 31 and a reference electrode holding part 32 for holding the plurality of reference electrodes 31; and a potential difference measurement device 4 for measuring a potential difference between the standard contact part 2 and each of the plurality of the reference electrodes 31. Each of the plurality of reference electrodes 31 is two-dimensionally arranged with intervals, and moves the reference electrode unit 3 along the surface of a concrete structure 11 so as to be arranged in order on a plurality of reference surfaces 11d, thereby measuring a potential difference between the standard contact part 2 and each of the plurality of reference electrodes 31.SELECTED DRAWING: Figure 1
