Non-destructive testing technology for quality inspection of hydraulic engineering

1. Technically, the accuracy of its testing and estimation needs to be further improved
The wave speed is greatly affected by external humidity, temperature, and media. In comparative tests at several construction sites, the measured values ​​of the test blocks often differ greatly; the standard parameter curves provided randomly are different in each region, so they are also different. Relative error.

2. The detection performance is relatively single, and comprehensive quality identification needs to be improved
With the application of new technology and new materials in water conservancy projects, in the quality appraisal, not only the quality status of concrete must be estimated, but also such as the quality of steel bars, the quality of steel structures, and the interaction of concrete and steel bars. Only then can the whole project be approved comprehensively and comprehensively.

Non-destructive testing technology is an effective way for quality prevention and control of water conservancy projects. With the continuous improvement of the level of non-destructive testing technology, the reliability of non-destructive testing is getting higher and higher. At present in most of the water conservancy projects I have been through, non-destructive testing has become the basis for quality treatment of hydraulic structures. However, non-destructive testing technology also has its own shortcomings. In the actual application process, we should take measures to avoid it, choose the correct testing method, and try to ensure the accuracy of the test results.
