Abstract

The invention discloses a mechanical property testing device under the impact load of an anchor body and a method of use thereof. The testing device includes: a gas booster device, which drives a piston to inflate gas; an air pressure adjustment device, which is arranged on the gas booster device, and The gas booster device is connected to set the initial value of the air pressure; the through-type pneumatic jack device is connected to the air pressure adjustment device; it receives the high-pressure gas output by the air pressure adjustment device and generates impact load on the anchor rod specimen to be tested; the universal testing machine The device is used to connect the two ends of the anchor specimen to be tested, receive the mechanical property change signal generated by the anchor specimen to be tested under the impact load, analyze and obtain the experimental results of the anchor specimen to be tested . The test device is easy to operate in the laboratory, has low cost and high accuracy, and can obtain multiple impact loads of different sizes, realizing the accurate measurement of the mechanical property change data of the anchor body under the impact load in the laboratory.

Description

technical field [0001] The invention relates to the technical field of mechanical performance testing, in particular to a mechanical performance testing device under the action of an anchor body impact load and a method for using the same. Background technique [0002] Bolts are the most basic component of roadway support in contemporary coal mines, and are also widely used in geotechnical engineering technology to reinforce the main body of slopes, tunnels (roadways), and dams. The bolt is a tension member that goes deep into the stratum. One end of the bolt is connected to the engineering structure, and the other end is deep into the stratum. The whole bolt is divided into a free section and an anchoring section. The function is to apply prestress to the anchor; the anchoring section refers to the area where the cement paste bonds the prestressed tendons to the soil layer, and its function is to increase the bonding friction between the anchor and the soil layer, increasin...
