Abstract

The invention provides an anchor rod (cable) supporting structure test and anchoring system performance integration test device and method and relates to the anchoring test technology field. The device comprises a frame, a loading mechanism, a test mechanism and a test piece. The frame comprises a pedestal and an operation bench. The loading mechanism includes a loading frame, a chuck, a surrounding rock stress loading oil cylinder, and a drawing hollow oil cylinder. The test mechanism includes monitoring mechanisms of a load, displacement, acoustic emission and the like. The test piece includes a rock test piece, an anchor rod (cable), an anchor net and the like. The loading mechanism and the drawing hollow oil cylinder are arranged above the pedestal, and a torsion motor and an anchor rod drilling machine are arranged on the operation bench. The rock test piece is placed between bearing plates, and one end of the anchor rod (cable) is fixed or anchored in the rock test piece through the chuck, and the other end passes through the drawing hollow oil cylinder. The device can test mechanical performance of the anchor rod (cable) and an anchoring component, can realize stress environment simulation of ''five-sided loading and one side empty'', and can carry out surrounding rock drilling response or anchoring system performance integration testing.

Description

technical field

[0001] The invention relates to the technical field of anchor rod testing, and in particular provides an anchor rod (cable) support structure test and an anchoring system performance comprehensive test device, and a method for using the device for testing. Background technique

[0002] At this stage, anchor support technology is widely used in engineering fields such as deep roadway and large-span underground cavern support, dam foundation and abutment reinforcement, rock and soil slope reinforcement, deep foundation pit support, water delivery and traffic tunnels, etc. On the one hand, the scientific support scheme can effectively guarantee the safety of project construction and production, and on the other hand, it can reduce costs to obtain maximum economic benefits. Experiments and engineering studies have shown that the essential function of bolts is to effectively reinforce the surrounding rock, prevent new cracks from opening in the surrounding rock an...
