Instant anchoring self-locking cone, instant anchoring anchor rod and construction method
The invention provides an instant anchoring self-locking cone which comprises a self-locking cone body installed on an anchor rod body and at least one anchoring part, the anchoring part is flexibly connected to the cone bottom of the self-locking cone body or the anchor rod body close to the cone bottom, and the anchoring part is located on the outer side of the cone face. When the anchor rod body is placed forwards in the anchor hole, the anchoring part synchronously moves forwards along with the self-locking cone body and is located on the outer side of the conical surface of the self-locking cone body. And when the anchor rod body is pulled back backwards, the conical surface of the self-locking cone body laterally extrudes the anchoring part, so that the anchoring part is propped against the hole wall of the anchor hole for quick anchoring. The invention further provides an instant anchoring anchor rod with the instant anchoring self-locking cone and a construction method. The counter force of the conical surface of the self-locking cone body to the anchoring part when the self-locking cone body is driven to synchronously move by the backward pulling force of the anchor rod body is utilized, so that the conical surface of the self-locking cone body laterally extrudes the anchoring part, the anchoring part is forced to abut against the hole wall of the anchor hole, the positive pressure between the anchoring part and the hole wall of the anchor hole is greatly increased, and instant anchoring of the anchor rod is achieved.
本发明提供了一种即时锚固自锁锥，包括安装在锚杆杆体上的自锁锥本体和至少一锚固件，所述锚固件柔性连接于自锁锥本体的锥底或锥底附近的锚杆杆体，使锚固件位于锥面外侧。当锚杆杆体在锚孔内向前置放时，锚固件随自锁锥本体向前同步移动且位于自锁锥本体的锥面外侧；锚杆杆体向后回拉时，自锁锥本体的锥面侧向挤压锚固件，使该锚固件抵紧锚孔孔壁而快速锚固。本发明还提供了具有上述即时锚固自锁锥的即时锚固锚杆及施工方法。本发明利用锚杆杆体后拉的拉力在带动自锁锥本体同步移动时其锥面对锚固件的反力，使自锁锥本体的锥面对锚固件进行侧向挤压，迫使锚固件抵紧锚孔孔壁，以大幅增大锚固件与锚孔孔壁之间的正压力，实现了锚杆的即时锚固。
