Description

Ultrasonic method concrete defect detection device

Technical Field

The utility model relates to a defect detection technical field, in particular to ultrasonic method concrete defect detection device.

Background

Concrete, or cement concrete, is a composite material formed by binding fine aggregate and coarse aggregate with cement (cement paste) and hardening them over time, and in the past, lime-based cement such as lime paste has been the most common, but hydraulic cement such as calcium aluminate cement or portland cement has also been used in some cases. When the aggregate is mixed with the dried portland cement and water, the mixture forms a slurry that is easily poured and formed. Cement reacts with water and other ingredients to form a hard matrix, which binds the materials together to form a durable rock-like material which has many uses and is widely used in civil engineering. An ultrasonic detector is needed when detecting concrete, and sound waves are propagation forms of mechanical vibration states of objects. Vibration is the back and forth movement of a mass point of a substance around its equilibrium position. The frequency of ultrasonic vibration is more than 20KHz, which exceeds the hearing of human ears, and the inaudible sound wave is called ultrasonic wave. The ultrasonic wave propagates in an elastic medium in a longitudinal wave mode, is a propagation mode of energy, and is characterized by high ultrasonic frequency, short wavelength and good beam emittance and directivity along a straight line within a certain distance.

Need use ultrasonic detector to detect the concrete when detecting the concrete defect, and the most structure of ultrasonic detector for concrete detection that generally uses at present is comparatively simple, need the one hand to hold ultrasonic detector when using, presses the button with the other hand, not only can't guarantee ultrasonic detector's stability, causes detection error easily, has increased staff's work burden moreover, for this reason, we propose an ultrasonic method concrete defect detection device and solve above-mentioned problem.
