The importance of non-destructive testing technology in hydraulic engineering
The non-destructive testing technology is characterized by its on-site, practicability, and quickness. It provides advanced scientific means for establishing engineer's engineering quality inspection work. It plays an increasingly important role in the overall quality monitoring of water conservancy projects.
1. Non-destructive testing technology is one of the legal methods for engineering quality accident detection and handling
In the "Concrete Structure Engineering Construction and Acceptance Specifications", it is clearly stipulated that when there is doubt about the representativeness of the strength of concrete specimens, non-destructive inspection methods or methods of drilling core samples from structures and components may be adopted. The strength of the concrete in the component is estimated as the basis for whether or not it should be treated.
2. Non-destructive testing technology is an effective means of project quality pre-control
With the improvement of the reliability of non-destructive testing, the test results are not only a basis for quality treatment, and more and more water conservancy projects have adopted it as a quality control method in the construction process, so that non-destructive testing technology is involved in construction. Under management. For example, the fresh concrete rapid tester can test the cement content and water-cement ratio in the fresh concrete of the tank within a few minutes, and estimate the 28d strength value, which plays a role of pre-monitoring.
3. Non-destructive testing technology is an important basis for quality inspection and evaluation of hydraulic engineering
On the basis of judging the engineering quality based on the measured values of standard test blocks, the comparison of non-destructive test results can not only verify the authenticity of the test blocks, but also reflect the true quality and differences of hydraulic structures. (责任编辑：admin) |
