Expanded-head uplift anchor rod and use method thereof
The invention discloses an expanded-head uplift anchor rod and a use method thereof, and is applied in the technical field of anchor rod piles. According to the technical scheme, the uplift anchor rodis characterized by comprising an anchor rod body and a variable-diameter reinforcement cage arranged at the bottom end of the anchor rod body; a fixing block is arranged on one side of the lower endof the anchor rod body; a sliding groove is formed in one side, deviated from the anchor rod body, of the fixing block in the horizontal direction; two sliding blocks are glidingly arranged in the sliding groove; two arc-shaped clamping plates opposite in openings are fixedly arranged on the two sliding blocks; a space for clamping a grouting pipe is formed between the two arc-shaped clamping plates; a driving device for driving the two arc-shaped clamping plates to get close to each other or get away from each other is arranged on the fixing block; and the driving device extends to the top end of the anchor rod body. The anchor rod and the use method have the technical effects as follows: a construction person can pull the grouting pipe out of a drilled hole easily and conveniently, andthe great convenience is brought to the construction process.
本发明公开了一种扩大头抗拔锚杆及其使用方法，应用在锚杆桩技术领域，其技术方案要点是：包括锚杆杆体和设置在锚杆杆体底端的变直径钢筋笼，所述锚杆杆体下端的一侧设置有固定块，所述固定块背离锚杆杆体的一侧沿水平方向开设有滑槽，所述滑槽内滑移设置有两个滑块，两个所述滑块上固定设置有开口相对的两个弧形夹板，两个所述弧形夹板之间形成有对注浆管夹持的空间，所述固定块上设置有驱动两个弧形夹板相互靠近或相互远离的驱动装置，所述驱动装置延伸至锚杆杆体的顶端。本发明具有的技术效果是：施工人员能够轻松便捷地将注浆管从钻孔内拔出，给施工过程带来极大的便利。
