On-site concrete structure strength measurement technology is divided into non-destructive methods and partial damage methods according to the degree of impact on the structure. The non-destructive method does not cause damage to the concrete structure, has simple equipment and easy operation, and can conduct repeated tests on concrete structures, which is convenient for large-scale operations. Range checking and other advantages. On the contrary, the partial damage method is subject to various limitations because it causes partial damage to the concrete structure, is difficult to inspect on a large scale, and is expensive. However, the partial damage method represented by drill core sampling is not only direct and reliable, but also indispensable in many cases. It is an effective method. At the same time, when testing the volume of the core sample model, the entire device needs to maintain sufficient stability to prevent core samples and test, so as to achieve the best testing state. However, the conventional device itself has a relatively simple structure. The lack of a stable structure makes the test structure potentially biased.
