Problems solved by technology

However, the indoor single test only reflects the single mechanical index of the bolt and supporting materials, and cannot reflect the actual effect and the most suitable construction technology that the bolt support material can achieve when it is applied to a specific condition, nor can it obtain the bolt work. The mechanical properties of the process when it is subjected to the superposition of multiple external forces

Abstract

The invention relates to the technical field of mine support, and particularly relates to a test bed for testing integrated mechanical properties of an anchor rod and a test method. The test bed comprises a pushing and mixing test mechanism, an installation pretension test mechanism, a bending load test mechanism, an axial load test mechanism, a shearing load test mechanism and an impact load test mechanism, wherein the pushing and mixing test mechanism and the installation pretension test mechanism are arranged on an installation test bed, and the bending load test mechanism, the axial load test mechanism, the shearing load test mechanism and the impact load test mechanism are arranged on a work test bed. By using the test bed, the installing and working process of the anchor rod can be simulated in a laboratory, and one or multiple combined external forces such as torsion, stretching, bending, shearing and impact are applied to the anchor rod; and mutually independent loading systems are adopted to apply corresponding loads to the anchor rod, so as to carry out independent experiments of various loads in the installing and working process of the anchor rod or a combined loading test of a plurality of any working stresses such as stretching, shearing and impact caused by installation stress and surrounding rock deformation, thereby effectively testing the integrated mechanical properties of the anchor rod under the combined action of various different external forces.

Description

technical field [0001] The invention relates to the technical field of mine support, in particular to a test bench and a test method for testing the comprehensive mechanical properties of bolts. Background technique [0002] Bolt 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. Bolt support is to anchor the bolt in the coal and rock body, tighten the nut at the end of the rod to apply prestress to the surrounding rock, and restrain the deformation, separation, swelling and slippage of the surrounding rock of the roadway. [0003] After the bolt support construction is completed, the stress on the bolt in the actual working state is very complicated, including the installation force of the support construction and the force on the bolt caused by the deformation and failure of the surrounding rock during the working process. [0004] During the construction of bolt...
