End grouting anchoring recyclable anchor rod
The invention discloses a recyclable anchor rod anchored through grouting at the end. Comprising a nut, an anchor rod support, an anchor rod support anchoring leg, a plum blossom cam shaft, an embedded shaft, a thread, an anchor head, an anchor rod, a grouting pipe, an expansion head, a blade, a drill bit, a spiral rib, an expansion head connecting cylinder, a concave spline locking device push-pull rod, a ball bearing support, a ball bearing, an inner bolt pin, a magnet, a plum blossom cam, a concave spline shaft inner hole, a concave spline shaft and a concave spline locking device. The drill bit has the beneficial effects that the expansion head can continuously drill into the soil body under the condition that the embedded shaft drives the concave head spline shaft to rotate, the spiral rib on the drill bit enables the drill bit to easily drill into the soil body, the blade can rotationally cut the soil body to form a broken zone, the broken zone is reinforced through pressure grouting to form the end expansion head, and the good anchoring effect is achieved; the embedded shaft is separated from the concave-head spline shaft lock through the effect of the plum blossom cam, and the recyclable anchor rod can be conveniently pulled out in the later period.
本发明公开了一种端部注浆锚固可回收锚杆，包括螺母、锚杆支架、锚杆支架锚固腿、梅花凸轮轴、内嵌轴、螺纹、锚头、锚杆、注浆管、扩大头、刀片、钻头、螺旋肋、扩大头连接筒、凹花键锁止器推拉杆、滚珠轴承支架、滚珠轴承、内销栓、磁铁、梅花凸轮、凹头花键轴内开孔、凹头花键轴、凹花键锁止器。本发明的有益效果是：扩大头可在内嵌轴带动凹头花键轴转动下向土体内部继续钻入，钻头上的螺旋肋使得钻头可以轻松地钻入，刀片可以旋转切割土体形成破碎带，压力注浆将破碎带加固形成端部扩大头，实现较好的锚固效果，内嵌轴中通过梅花凸轮作用与凹头花键轴锁分离，便于后期拔出可回收锚杆。
