An anchor rod or anchor cable corrosion resistance test device comprises a test box and an anchor test rack arranged in the test box, an insulation and heat-insulation door is arranged at the front side of the test box, the box body and the insulation and heat-insulation door of the test box are made from an insulation and heat-insulation material, electrothermal tubes are arranged at the rear side part and the bottom in the test box, a humidity adjusting sprayer, a temperature sensor and a humidity sensor are arranged in the test box, a corrosion solution injection hole is arranged in the right side of the test box, and an operating console is arranged at the right side of the test box. The invention also discloses a test method of the anchor rod or anchor cable corrosion resistance testdevice. The test device and the test method have the advantages of easiness in control and adjustment of a corrosion test environment, easiness in matching of the simple anchor rod or anchor cable anchoring test rack with the test box, adjustable length of the anchor rod or anchor cable anchoring test rack, easy dismounting and repeated use of the anchor rod or anchor cable, and easiness and fastness in performing various basic tests.
Description
technical field [0001] The invention belongs to the technical field of coal mine roadway support, and in particular relates to an anti-corrosion test device and a test method for an anchor rod or anchor cable. Background technique [0002] At present, anchor rod or anchor cable support has become a safe and efficient main support method for coal mine roadways, and has been widely promoted and applied in coal mine roadways in my country. Anchor rod or anchor cable support is to anchor the anchor rod or anchor cable in the coal rock body, tighten the rod (cable) end nut (lock), apply pre-tightening force to the surrounding rock, and restrain the deformation, separation and fragmentation of the roadway surrounding rock. Swelling and slippage. It is of great significance to study the axial load and axial deformation performance of bolt or cable support in the process of deepening the study of bolt or cable support mechanism, improving the reliability of bolt or cable support, a...
