Simulation verification device of nondestructive testing equipment

Abstract

The invention relates to a simulation verification device of nondestructive testing equipment, which comprises a concrete block, a first main scale square grid and a second main scale square grid are respectively arranged on the first surface and the second surface of the concrete block, the first surface and the second surface are parallel to each other, and the projection of the first main scale square grid on the second surface coincides with the second main scale square grid; the to-be-tested object simulation assembly is pre-embedded in the concrete block and at least comprises two reinforcing meshes, a plastic pipe and a wire arranged in the plastic pipe, the two reinforcing meshes are the first reinforcing mesh and the second reinforcing mesh respectively, the plastic pipe is located between the first reinforcing mesh and the second reinforcing mesh, the first reinforcing mesh and the second reinforcing mesh are arranged in parallel, and the included angle between the first surface and the second surface is less than 5 degrees. Compared with the prior art, the measuring precision of the nondestructive testing equipment in practical application can be improved.

Description

technical field [0001] The invention relates to the field of power transmission and transformation engineering equipment, in particular to a simulation calibration device for non-destructive testing equipment. Background technique [0002] The safety of concrete engineering structure is closely related to the quality of the project, especially in the construction of important power facilities such as substations, concrete detection is particularly important. At present, various non-destructive testing equipment is being updated day by day, and testing technology is constantly improving. How to give full play to the role of non-destructive testing technology in the quality supervision process, especially the application of non-destructive testing technology for the safety performance evaluation of concrete structures is of great significance to engineering practice. . [0003] Common safety hazards in concrete structures include: steel bars are not constructed as required, s...

Problems solved by technology

[0005] According to the principle of non-destructive testing equipment, there are X-rays, infrared imaging, radar waves, electromagnetic inductance, etc. The accuracy of non-destructive testing equipment affects the test results, and inaccurate test results will bring serious safety hazards. However, in the on-site testing environment Complexity, the detection medium is uncertain, and will be affected by the measured object during the detection process. The actual detection scene cannot judge the accuracy of the non-destructive testing equipment. Improper use of the
