Multifunctional testing machine for deep surrounding rock anchoring performance

Abstract

The invention discloses a multifunctional testing machine for deep surrounding rock anchoring performance, which comprises a servo hydraulic control system, an anchoring body vertical pulling and pressing system, a horizontal shearing system and an anchor rod anchor rope shearing system, wherein the servo hydraulic control system is connected with each of the hydraulic oil cylinders of the anchoring body vertical pulling and pressing system, the horizontal shearing system and the anchor rod anchor rope shearing system; the servo hydraulic control system comprises a hydraulic station and a computer control console; a servo hydraulic loading control system is arranged on one side of a base and is connected with the hydraulic oil cylinders of the vertical pulling and pressing system, the horizontal shearing system and the anchor rod anchor rope shearing system; and the computer control console controls the oil feed quantity of the hydraulic station to the oil cylinders of other systems and the oil return quantity. The multifunctional testing machine disclosed by the invention can more truly reflect the deformation rules of the surrounding rock of underground works, more effectively simulate the support under fracture deformation conditions of surrounding rock of underground cavities, and realize the testing of the anchoring performance of an anchor rod, an anchor rope and other support structures.

Description

technical field [0001] The invention relates to a multifunctional testing machine for deep surrounding rock anchorage performance testing and research in deep underground engineering fields such as mining, energy, hydropower, transportation, and national defense. Background technique [0002] With the development of the country's economy and the advancement of basic construction, there are more and more deep underground projects such as mines, energy, hydropower, transportation, and national defense. At present, with the popularization and application of bolt technology, bolt and cable support technology is basically adopted for the support of surrounding rock in deep geotechnical engineering, especially in deep mine engineering, coupling support technology such as anchor, mesh and cable injection is used. The engineering usage of anchor rod and anchor cable is very large, and the anchoring performance of anchor rod and anchor cable is related to the safety of the project. T...

AI Technical Summary

Problems solved by technology

[0011] The purpose of the present invention is to solve the single function of the anchoring performance experimental device in the prior art, without considering the effect of the surrounding rock, especially the coupling effect of the anchor rod, anchor cable and supporting member and the anchoring body of the surrounding rock, which can only be carried out The simple static load anchorage performance test cannot carry out the joint anchorage performance test of anchor rod and anchor cable; a multifunctional test machine for deep surrounding rock anchorage performance is provided; it can more truly reflect the deformation law of underground engineering surrounding rock, and is more effective It is a multifunctional test device that simulates the support under the condition of underground cavern surrounding rock rupture and deformation, and realizes the anchorage performance test of anchor rods, anchor cables and other support structures.
