Abstract

The invention discloses a size-adjustable anchor rod pull-out test platform, and belongs to the field of mine engineering. The platform comprises a platform main body, and supporting legs and universal wheels are arranged at a bottom of the platform main body; multi-specification similar geologic body forming boxes are arranged on the platform main body; lengths and widths of box bodies of the multi-specification similar geologic body forming boxes can be adjusted according to test requirements so as to pour a similar model; the multi-specification similar geologic body forming boxes are driven by a worm and a worm gear, and a test body is conveyed out of the box bodies of the multi-specification similar geologic body forming boxes; and an anchor rod pull-out test box and a model cleaningdevice are included. The platform belongs to non-electric control equipment and is low in cost; a pure mechanical structure design is adopted, and operation is simple and safe; and anchor rod pull-outtests with different anchorage lengths can be performed by forming similar geologic body blocks with different specifications, and the test body can be conveniently and quickly taken out for the nexttest.

Description

technical field [0001] The invention relates to the technical field of mine engineering, in particular to an adjustable bolt pullout test platform. Background technique [0002] Bolt support technology has the advantages of strengthening rock mass, reducing the weight of structures and saving engineering materials. In recent years, it has gradually developed into the main technical means of geological disaster prevention and treatment. has been widely used. In actual engineering, due to the complexity and concealment of the anchorage system damage, the anchorage strength test technology needs to be further studied. [0003] However, on-site detection is often affected by environmental conditions and uncertain factors, and it is difficult to carry out detection tests, which makes it difficult to accurately grasp the anchorage strength of bolts. The simulation test of similar materials has always been the main method of mine engineering research. Its essence is to use materi...
