Abstract

The invention belongs to the technical field of testing of the corrosion degree of a steel bundle, and particularly discloses a device and a method for testing the corrosion degree of a steel bundle. The device for testing the corrosion degree of the steel bundle comprises a power supply source, a data processing system, a tester, a temperature sensor, a tested steel bundle, a 1-milliohm standard resistor, and a 10-milliohm standard resistor, wherein the power supply source supplies power for a tester; the tester collects data measured by the temperature sensor, the tested steel bundle, the 1-milliohm standard resistor and the 10-milliohm standard resistor; and the data processing system receives the data of the tester for processing through a communication interface, calculates a corrosion degree value of the tested steel bundle, outputs and displays the value. The device can intuitively reflect the corrosion degree of the steel bundle, can remove the effect of a temperature coefficient of the steel bundle, measures thermoelectric force, and measures the self temperature drift and the self initial error. Therefore, the measurement accuracy, speed and sensitivity are greatly improved, and the test stability and reliability are enhanced.

Description

technical field [0001] The invention relates to the technical field of steel beam corrosion degree testing, in particular to a steel beam corrosion degree testing device and a testing method thereof. Background technique [0002] At present, the monitoring / detection of the corrosion state of the tension / sling cables in the anchorage area of ​​the bridge cable girder and cable tower of the cable support system is a big problem in the engineering field. In engineering practice at home and abroad, there are many methods for steel cable detection, including ultrasonic, magnetic, ray, etc., each method applied to different detection objects has its own defects, such as magnetic leakage, electromagnetic and other aspects of testing at both ends of the cable There will be end effects. Although the test accuracy of the ray method is high and the test effect is good, its disadvantage is that the test time is too long, and the use safety risk is great. Ultrasonic testing requires th...
