Static and dynamic combined intelligent pre-warning anchor rod

The invention relates to a static and dynamic combined intelligent pre-warning anchor rod. The intelligent pre-warning anchor rod consists of a hollow grouting rod body (1) and a solid rod body (3) which are sleeved together through a sleeve (2) and are bonded and anchored to wall rock of a hole wall, wherein the sleeve (2) is not bonded to the wall rock of the hole wall; the solid rod body (3) can penetrate through a large internal diameter section of the sleeve (2), but part of the rod body cannot penetrate through a small internal diameter section of the sleeve (2); a displacement sensor (10) is fixed in the sleeve, and is connected with an intelligent pre-warning device (12) outside an anchor hole by penetrating through a communication wire (11) of the hollow grouting rod body (1); and the displacement sensor (10) can be a mechanical wheel, an ultrasonic range finder or an infrared range finder and the like. On the basis of the original static and dynamic combined anchor rod, the static and dynamic combined intelligent pre-warning anchor rod is provided with functions of intelligent measurement and pre-warning, can realize continuous and reliable supporting, safe monitoring and pre-warning in the field of surrounding rock dynamic disaster monitoring and control, and is suitable for market popularization and application.
