METHOD FOR DETERMINATION OF REINFORCED-CONCRETE LINING PLATES OF MELIORATIVE CHANNELS

摘要

Method for determination of micro-cracks of reinforced-concrete plates of lining of meliorative channels includes mounting of measuring installation that consists of voltmeter in which polarization compensator is structurally placed, measuring conductive lines and measuring cooper sulfate comparison electrodes, placement of measuring electrodes at given observation network in places of possible development of fracturity, measurement of potential difference of natural filtration electric field. Measured natural electric field of filtration is brought to existence through wetting places of contacts of cooper-sulfate electrodes and reinforced-concrete lining plates with filtering liquid. As filtering liquid one uses distillated water in amount of about 50 ml per one measurement.
