Anchoring Quality Monitoring Device and Application Method for Adding Resistance and Deformation Anchor Rod/Anchor Cable

Abstract

The invention relates to an anchor quality monitoring device for increased resistance deformation anchor bolts / ropes and an application method of the anchor quality monitoring device. The device comprises increased resistance deformation anchor bolts / ropes, displacement measurement units, data acquisition equipment, an information transmission device and a central processing system, wherein the displacement measurement units arranged on the anchor bolts / ropes measure displacement of bolt bodies (rope bodies) in the operation process; the data acquisition equipment and the information transmission device collect and transmit data to the central processing system; and the central processing system converts the transmitted displacement data into drawing force data of the anchor bolts / ropes according to tension-displacement curves of the anchor bolts / ropes. The device can monitor and provide anchor forces of the anchor bolts / ropes and wall rock displacement simultaneously, find the failed anchor bolts / ropes timely, AND forecast wall rock collapse and damages, thereby effectively avoiding safety accidents, and greatly lowering the monitoring cost.

Description

technical field [0001] The invention relates to the field of geotechnical engineering anchoring, in particular to an anchor rod / anchor cable anchoring quality monitoring device and an application method thereof. Background technique [0002] With the in-depth development of large-scale geotechnical engineering construction, the geological conditions are becoming more and more complex, and the surrounding rock often shows the characteristics of large deformation. When the deformation of the surrounding rock is large and exceeds the range that the anchor rod / cable can bear, it will lead to the failure and damage of the anchor rod / cable, and then cause the instability and destruction of the underground engineering. [0003] In view of this situation, the applicant has developed corresponding resistance-increasing deformation anchors / cables (201110368935.1, 201110368805.8) to adapt to these situations. The following problems were found during the application of the above-mentio...

AI Technical Summary

Problems solved by technology

The following problems were found during the application of the above-mentioned patented products: In order to grasp the stability of the surrounding rock and the reliability of the anchoring system, it is necessary to monitor the anchoring quality of the bolt / anchor cable (including anchoring force and displacement of the surrounding rock) for a long time. At present, there is no corresponding The equipment can monitor the above two variables at the same time, but the cost of special detection equipment is high, and there are various disadvantages

These measurements will consume a lot of manpower and material resources for on-site measurement and data processing, and may cause measurement errors due to measurement differences between individuals

In addition, this measurement cannot actively measure and predict emergencies that may occur at any time
