Abstract

The invention discloses an adaptive pressure-relieving grouting bolt, which overcomes the problem in the prior art that the reinforcement ability of the bolt needs to be improved. The invention includes an anchor body, an adaptive locking device, a grouting hole, a grout stopper, a grout stopper backing plate, a fastening nut and a grout stopper, wherein the anchor rod body is a hollow tube, and the anchor rod body is sleeved on In the self-adaptive locking device, there is a grouting hole on the side wall of the bolt body sleeved in the rock, and the side of the bolt body protruding out of the rock passes through the middle part of the grout stopper and the grout stopper backing plate. , after the self-adaptive locking device is socketed, the connection is fixed through the fastening nut, and the end of the anchor rod body is provided with a grout plug. The self-adaptive locking device includes a locking wedge mechanism, an upper sleeve, an isolation rubber ring, a positioning lower sleeve, a grout plug nut, a screw washer and a spring. In this technology, the upper sleeve releases the pressure of the bolt body by cutting the pre-unloading protrusion of the bolt body, effectively controlling the large deformation of the surrounding rock, improving the anchoring efficiency, and meeting the requirements of bolt support technology in deep geotechnical engineering.

Description

Technical field [0001] The present invention relates to the field of reinforcement protection in geotechnical engineering, in particular to an adaptive pressure relief grouting anchor. Background technique [0002] With the continuous increase in the depth of global mineral resources, various engineering geological disasters are increasing, such as mine impact ground pressure and soft rock deformation, such as disasters, the safety and efficiency of deep resources have caused a huge threat. The laneway of the traditional anchor support is far from resisting the instantaneous transformation impact load generated by the rock burst, thereby occurs an anchor break and a damaged roadway. [0003] At present, in the underground engineering support, it is usually suspended in the upper stable rock formation by the anchor, and the anchoring of the anchor end of the anchor end in the project is used to increase the resin anchor. There is a problem when there is a problem, and once the anc...
