Recyclable anchor rod
The invention provides a recoverable anchor rod. The recoverable anchor rod comprises a hollow outer rod, a sliding inner rod is arranged on the outer rod, a plurality of telescopic anchoring heads are arranged on the outer rod, an inclined pushing mechanism is arranged at one end of each anchoring head and located between the inner rod and the outer rod, a vertical pushing mechanism is arranged on one side of each inclined pushing mechanism, and a pushing seat is arranged between each vertical pushing mechanism and the corresponding anchoring head. When the inner rod continues to move downwards, the anchoring head is driven by the inclined pushing mechanism to move upwards in an inclined mode, and the phenomenon that the anchoring head cannot be inserted when encountering a firm part in a rock-soil body is avoided. And the outer rod is provided with a plurality of anchoring heads capable of extending out, so that the whole body formed after the anchor rod and concrete are solidified can be tightly combined with a soft rock-soil body, and the phenomena that materials are wasted and the construction cost is increased due to the fact that the anchor rods are arranged densely are avoided. The anchoring head of the whole device can not be recycled, all other structures can be recycled, and the phenomena that a large amount of underground space is occupied, underground garbage is formed, and underground environment pollution is caused are avoided.
本发明提供一种可回收锚杆，包括中空的外杆，外杆上设有滑动的内杆，外杆上设有多个伸缩的锚固头，锚固头一端设有斜推机构，斜推机构位于内杆与外杆之间，斜推机构一侧设有竖推机构，竖推机构与锚固头之间设有推进座。当内杆继续向下运动，锚固头在斜推机构的驱动下倾斜向上运动，避免锚固头遇到岩土体中坚固部分不能插入的现象发生。外杆上设置有多个能够伸出的锚固头，以使锚杆和混凝土固结后的整体与松软岩土体能够紧密结合，避免布置相对密集的锚杆，导致材料浪费、施工成本增加的现象发生。整个装置除了锚固头不能够回收利用外，其它所有结构都能够回收利用，不会占用了大量地下空间，形成地下垃圾，造成地下环境污染的现象发生。
