Automatic centering rotary jet grouting expanded-head anchor cable
The invention provides an automatic centering rotary jet grouting expanded head anchor cable, and relates to the technical field of geotechnical engineering anchoring. The automatic centering rotary spraying expanded-head anchor cable comprises an anchor cable body and a first positioning assembly, a plurality of evenly-distributed fixing cylinders are arranged on the outer side of a positioning plate, springs are connected into the fixing cylinders, one ends of the springs are connected with movable plugs, one sides of the movable plugs are fixedly connected with movable rods, and the movable rods are fixedly connected with the first positioning assembly. And a sliding hole is formed in one end of the fixed cylinder. A plurality of anchor cables can be installed by installing the first positioning assembly outside the anchor cables and forming a plurality of positioning holes in the positioning plate, the movable rod can stretch out and draw back in the fixing cylinder through the spring, in the process of pushing the anchor cables, the movable rod can smoothly enter the bottom expanding body, the anchor cables are prevented from deviating from the anchoring holes, and the anchor cables are automatically aligned to the bottoms of the anchoring holes; and meanwhile, the anchoring force can be increased, and the overall pulling resistance can be improved.
本发明提供一种自动对中的旋喷扩大头锚索，涉及岩土工程锚固技术领域。该自动对中的旋喷扩大头锚索，包括锚索和第一定位组件，所述定位板的外侧设置有多个均匀分布的所述固定筒，所述固定筒的内部连接有弹簧，所述弹簧的一端连接有活动塞，所述活动塞的一侧固定连接有所述活动杆，所述固定筒的一端设置有滑孔。通过在锚索外安装第一定位组件，通过定位板上设置多个定位孔可以安装多个锚索，通过弹簧可以使活动杆在固定筒内进行伸缩，在推进锚索的过程中，活动杆可以顺利进入底部扩大体内，防止锚索偏离锚固孔，自动对准锚固孔底部，始终保持均匀分布，受力均衡，同时可以增加锚固力，提高整体抗拔能力。
