The invention relates to the technical field of anchor rods, and discloses a recyclable pressure-bearing type anchor rod. The anchor rod comprises an anchor rod body, an isolation cylinder and a firstfixing plate, wherein the first fixing plate is fixed in a soil body; the isolation cylinder is arranged in the soil body; the inner end of the isolation cylinder abuts against the first fixing plate; the outer end of the isolation cylinder is deviated from the first fixing plate, extends towards the outer side of the soil body and is exposed outside the soil body; the anchor rod body is arrangedin the isolation cylinder in a penetrating mode; the position between the anchor rod body and the inner side wall of the isolation cylinder is provided with a gap; an anchor head is arranged at the inner end of the anchor rod body; threads are arranged on the anchor head; the first fixing plate is provided with a first screw hole; the threads on the anchor head are connected to the first screw hole in a threaded mode; the outer end of the anchor rod body is provided with an anchoring head and an anchoring plate; the anchoring plate is pressed against the outer end of the isolation cylinder; and the anchoring head penetrates through the anchoring plate and extends to the outer side of the soil body. According to the anchor rod, the anchor head is connected to the first fixing plate in a threaded mode, the isolation cylinder sleeves the outer side of the anchor rod, when the anchor rod is screwed, the anchor rod cannot be interfered by the external soil body, and therefore the anchor rod can be conveniently mounted and recycled.
Description
technical field [0001] The patent of the present invention relates to the technical field of anchor rods, in particular, it relates to recoverable pressure-bearing anchor rods. Background technique [0002] As one of the main support forms of underground engineering and rock slopes, bolts play an important role in maintaining the stability of civil engineering, especially in jointed and fissured rock masses, the reinforcement effect of bolts on rock masses is very obvious. [0003] At present, the whole bolt is divided into a free section and an anchor section. The free section refers to transmitting the tension at the head of the anchor to the anchor area, and its function is to apply prestress to the anchor; the anchor section refers to the cement slurry will prestress The function of the area where the stress tendon is bonded to the soil layer is to increase the bonding friction between the anchor body and the soil layer, increase the pressure bearing effect of the anchor...
