AI Technical Summary
Existing technologies lack a testing device that can simulate different stress environments in anchor pull-out tests, is applicable to various types of rock and soil materials, observe the effects of different pull-out rates, and achieve real-time monitoring of strain across the entire range.
A visualized indoor pull-out test device for anchor bolts is provided, including a confining pressure loading system, an anchor bolt pull-out system, and a strain monitoring system. Utilizing a three-dimensional frame, loading jacks, a transparent loading plate, stress monitors, strain monitors, and a non-contact full-field strain monitor, it simulates the actual engineering environment and monitors the strain changes of the anchor bolts and rock mass in real time.
It enables dynamic monitoring of anchor bolts under different stress environments, observes the impact of different pull-out rates on the anchoring system, is suitable for studying the action mechanism of various types of anchor bolts, and has a simple structure and is easy to operate.
