Problems solved by technology

Due to the influence of the high ground stress in the deep tunnel, the surrounding rock will have a large amount of deformation. When the surrounding rock undergoes large deformation, the traditional rigid anchor is easy to be broken, thus losing the anchoring effect. Therefore, the deformation can be effectively buffered It is necessary to give pressure to the anchor rod
[0003] In order to solve the above-mentioned technical problems, the patent No.: 201520177865.5 discloses a large-deformation yielding anchor rod, which can allow the surrounding rock to generate large deformation and buffer large deformation pressure. However, the above-mentioned anchor In the process of rod yielding, it is impossible to monitor the yielding amount of the yielding anchor rod in real time, so that the support effect of the anchor rod cannot be effectively judged, which is not conducive to grasping the real-time support status of the anchor rod

Abstract

The invention relates to a yielding anchor rod capable of monitoring the yielding amount in real-time, which comprises a main rod body, wherein a main anchor body is arranged on the front end of the main rod body, and is inserted into an insertion chamber at the front end of the main rod body; the main anchor body is connected with the main rod body through a spring; a pull rope is arranged on the main anchor body; one end of the pull rope stretches out of the main rod body and is connected with a displacement reading unit; the displacement reading unit is used for displaying the displacement amount of the pull rope. The yielding anchor rod is ingenious in design, compact in structure, large in anchor rod yielding amount, capable of monitoring the yielding amount of the anchor rod in real-time and timely judging the support quality, realizes a circulation support process of primary support-yielding support-re-reinforced support, and is good in support effect.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a yield anchor with real-time monitoring yield. Background technique [0002] As a supporting tool, bolts are widely used in deep tunnels. Due to the influence of the high ground stress in the deep tunnel, the surrounding rock will have a large amount of deformation. When the surrounding rock undergoes large deformation, the traditional rigid anchor is easy to be broken, thus losing the anchoring effect. Therefore, it can effectively buffer the deformation. It is necessary to let the pressure out of the anchor rod. [0003] In order to solve the above-mentioned technical problems, the patent No.: 201520177865.5 discloses a large-deformation yielding bolt, which can allow the surrounding rock to undergo large deformation and buffer large deformation pressure. However, the above-mentioned anchor In the process of rod yielding, it is impossible to monitor the yielding ...
