[0002] In the field of engineering construction technology, anchor rods are widely used in highway engineering slope protection, tunnel construction and other projects due to their simple process and low cost. As a means of judging the quality of anchor rods, anchor rod pull-out test plays a role in evaluating the performance and anchoring force of anchor rod anchoring system.

[0003] The pull-out test device for anti-floating anchor rods is divided into laboratory test device and field test device. The laboratory test device has a high degree of automation and complete functions, but is limited to indoor pull-out tests. The field test device must meet the requirements of being able to be assembled quickly and adapt to various test conditions.

[0004] In actual construction sites, in order to conduct tests quickly, the existing technology usually uses a steel beam to freely place the test device on two jacks. Since the steel beam is directly placed on the two jacks, it has a large degree of freedom and is prone to misalignment during the test, which affects the test results on the one hand and poses a safety hazard on the other. In order to avoid the above problems, the existing technology also proposes an integrated pull-out test reaction support, in which the components are welded and fixed. Although it does not need to be installed when used, the entire device is large in size, and it is time-consuming and labor-intensive to carry and position, and cannot achieve the desired effect.

[0005] Therefore, it is necessary to propose a detachable anti-floating anchor pull-out test reaction support to solve this problem. Utility Model Content
