Embodiment Construction

[0053] The invention is based on three-dimensional health detection of concrete with steel bar electrodes as antenna arrays.

[0054] see figure 1 . Antenna array A and antenna array B are installed at relative positions up and down in the three-dimensional concrete. All antennas in the antenna array are made of steel bars and installed on the same plane. The number and arrangement of antennas in antenna array A and antenna array B are the same, and The planes are parallel to each other.

[0055] The antennas in antenna array A and antenna array B are arranged in the same way, that is, n rows are evenly distributed on the same horizontal plane, and m columns are antennas made of steel bars, where m and n are integers greater than or equal to 1, and the steel bar antennas are pre-embedded in concrete.

[0056] Such as figure 2 , image 3 As shown, the antenna is made of a steel bar electrode, and its shape is as figure 2 The dual type shown or as image 3 circle shown. ...

Abstract

The invention discloses a three-dimensional concrete health detection method based on a reinforcing steel bar antenna and a detection circuit thereof. An antenna array A and an antenna array B made of reinforcing steel bars are additionally mounted in corresponding positions up and down inside three-dimensional concrete; planes where the antennas of the two antenna arrays are located are parallel to each other; the detection circuit emits and receives electromagnetic waves through the antennas in the antenna arrays and carries out the heath detection on concrete; a microprocessor in the detection circuit is adopted to communicate with a detection server through a communication interface, instructions of the detection server can be received, and then detection control can be performed through the detection circuit; the microprocessor is used for setting signal frequency of a signal generator, electromagnetic valves can be transmitted out through transmission antennas, an in-phase analog-digital converter output data result and an orthogonal analog-digital converter output data result can be obtained through a demodulation circuit, and whether a concrete material has internal defects can be judged. The health situation of three-dimensional concrete can be monitored in real time and a remarkable effect can be achieved.

Description

(1) Technical field [0001] The invention belongs to building material detection and relates to concrete quality detection, in particular to three-dimensional concrete crack detection based on steel bar 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 ZL 2006 1 00200932.8 Chinese patent "Concrete Damage Detection ...
