Inverted wedge type recoverable anchor rod
The invention discloses an inverted wedge type recoverable anchor rod which comprises a threaded rod body with threads on the outer side. One end of the threaded rod body serves as an anchorage section and is provided with a first nut for fastening, and the other end of the threaded rod body serves as an anchor head and is provided with a tray and a second nut; the outer side of the threaded rod body located between the tray and the first nut is connected with a threaded casing pipe system through surface threads, the threaded casing pipe system is composed of multiple threaded casing pipe subsystems, and the threaded casing pipe subsystems are fixedly connected; each threaded casing pipe subsystem comprises a threaded steel pipe and a wedge, the threaded steel pipes are fixedly connected with the wedges, threaded casing pipes and wedges of every two adjacent threaded casing pipe subsystems are connected. After mounting of the anchor rod is completed, a broken rock-soil body is firmly hung on a stable rock-soil body, therefore, the overall strength of rock is increased, the uplift bearing capacity of the anchor rod is improved, and meanwhile the force of the anchor rod is more reasonable. A support effect can be played as soon as possible after mounting, the rod body can be taken out for temporary support, and materials are saved.
