The invention provides an anchoring structure pullout test device comprising a loading frame, a reaction frame and an anchoring structure model. The loading frame and the reaction frame are slidably connected. The anchoring structure model is detachably connected with the loading frame and the reaction frame respectively. The loading frame is fixedly connected with a loading chassis. The reaction frame is provided with a pressure sensor. The beneficial effects of the anchoring structure pullout test device are that an indoor test used for anchoring structure pullout force is realized by the anchoring structure pullout test device on the basis of a pressure tester so that the pullout test of mechanical property of the anchoring structure model can be conveniently realized, and the pullout test is stable in load and great in test effect; and an anchoring structure pullout test method is easy, stable and reliable in test operation and can be used for the indoor test of anchoring structure pullout force on the basis of the pressure tester so that the pullout test of mechanical property of the anchoring structure model can be accurately realized.
Description
technical field [0001] The invention relates to the technical field of pull-out load application tests, in particular to an anchoring structure pull-out test device and a test method. Background technique [0002] Anchoring technology is an effective means of rock and soil reinforcement, and its anchoring effect is generally evaluated by a pull-out force test. Indoor anchoring structure pullout test is a commonly used method for testing the pullout force. It can consider a variety of different rock and soil conditions to analyze the deformation and failure process of the anchorage structure, interface stress distribution, rheological instability and other mechanical properties. The research results It has important guiding significance for the design of on-site anchoring and support. The pull-out test of the anchorage structure requires the use of the testing machine to provide a certain pull-out load on the anchor rod, and the pressure testing machine commonly used in the ...
