Two-dimensional concrete health monitoring method based on reinforcing steel bar electrodes

Abstract

The invention discloses a two-dimensional concrete health monitoring method based on reinforcing steel bar electrodes. N mutual-parallel reinforcing steel bar electrodes linearly laid on a same horizontal plane in two-dimensional concrete are connected to a concrete parameter measurement circuit, under control of a microprocessor, signals with different frequencies are emitted by a sine signal generator, and through concrete voltage amplification and resistance voltage amplification, different-frequency impedance modulus and phase positions of all the electrodes on the two-dimensional concrete are measured. The same-specification normal two-dimensional concrete impedance modulus and phase position values measured under different frequencies are compared with those of the measured two-dimensional concrete, the health condition of the two-dimensional concrete is determined, and a specific position of an unusual condition of the concrete is found out. The method has the beneficial effects that the two-dimensional concrete health condition is real-timely monitored, quality evaluation of buildings is timely done, and concrete lesions are forecasted and forewarned. The invention provides the two-dimensional concrete parameter measurement circuit convenient and reliable to use and remarkable in detection effect.

Description

(1) Technical field [0001] The invention belongs to building material detection and relates to concrete quality testing, in particular to two-dimensional concrete health monitoring based on reinforced electrodes. (2) Background technology [0002] Concrete is an important engineering material widely used in housing construction, bridge engineering, water conservancy engineering, etc. Concrete health detection and monitoring instruments are technical means to ensure the safe and long-term operation of concrete. Prediction, prediction, and diagnosis of concrete health are one of the main problems urgently needed to be overcome in the world today. Highways, bridges, dams, and other industrial and civil buildings all require regular or real-time health testing and monitoring. However, the existing concrete quality detection methods can not fully meet the needs of construction and development. The patent number is ZL2006100200932.8 Chinese patent "Concrete Damage Detection Meth...
