Abstract

The invention relates to an anchor rod anchoring quality detector, and belongs to the non-destructive test technical field. The detector comprises a central control module, a guided wave excitation module, a power amplification module, a channel switching module, a signal conditioning module, a data acquisition module, a user interaction module, a rechargeable battery module, a power adapter and a guided wave transceiving transducer. The detector adopts high-frequency and low-frequency guided wave dual-mode detection, and can comprehensively evaluate the anchor rod anchoring quality. The detector has simple operation, can display detection results in real time, can be manufactured into a plurality of modes such as a portable type, a vehicle-borne type, a stationary type and the like, and facilitates working personnel to be capable of rapidly detecting the anchor rod anchoring quality in practical engineering.

Description

technical field [0001] The invention relates to a bolt anchoring quality detector. The instrument uses a method of combining high and low frequency guided waves to carry out non-destructive testing of the anchorage quality of the bolt, and can detect the length of the bolt on site, the effective anchoring length, and the anchoring force. It is suitable for the quality inspection of bolt anchorage in various geotechnical engineering such as coal mine roadways and underground tunnels, and belongs to the field of non-destructive testing. Background technique [0002] As an important part of the support system, bolts are widely used in the reinforcement and support of underground roadways and surrounding rocks of slopes. In engineering practice, the anchorage quality of the anchor is directly related to the safety of the project. Once the anchor fails, it will pose a huge threat to the stability of geotechnical engineering, and even cause catastrophic consequences. [0003] The...
