Recyclable anchor rod and recycling method thereof
The invention relates to a recoverable anchor rod and a recovery method thereof.The recoverable anchor rod comprises an anchor rod body which comprises a free-section anchor rod body and an anchoring-section anchor rod body which are connected with each other through a recovery device; the recovery device comprises a shell, an annular hole used for being connected with the free section anchor rod and allowing the free section anchor rod to move is formed in the top of the shell, a threaded hole used for being connected with the anchoring section anchor rod is formed in the bottom of the shell, and annular teeth and a force bearing table matched with the annular teeth in shape are arranged in the recovery device. When the anchor rod is in a tensioned state, the free section anchor rod is driven to rotate in the first direction, the free section anchor rod rotates and drives the recovery device to generate first torque in the first direction, and the recovery device is driven to rotate in the second direction. And the anchoring section anchor rod generates a second torque which is opposite to the first torque and is in the second direction, so that the free section anchor rod is separated from the anchoring section anchor rod under the action of the first torque and the second torque which are opposite to each other.
本发明涉及一种可回收锚杆及其回收方法，其中，可回收锚杆包括锚杆，其包括通过回收装置彼此相连的自由段锚杆和锚固段锚杆；回收装置，包括壳体，壳体顶部具有用于连接并允许自由段锚杆移动的环形孔，壳体底部具有用于连接锚固段锚杆的螺纹孔，其中，回收装置内设有环形齿和与环形齿形状适配的承力台，且承力台构造为能够随锚杆的张拉位移而与环形齿啮合，其中，在锚杆处于张拉状态之时，驱动自由段锚杆沿第一方向产生转动，自由段锚杆转动并驱动回收装置产生沿第一方向的第一扭矩，锚固段锚杆产生与第一扭矩反向的沿第二方向的第二扭矩，使得自由段锚杆在彼此反向的第一扭矩和第二扭矩作用下与锚固段锚杆脱离。
