Anti-floating anchor rod rib and anti-floating anchor rod for preventing top anchoring grouting body from cracking
The invention relates to an anti-floating anchor rod rib and an anti-floating anchor rod for preventing a top anchoring grouting body from cracking. The anti-floating anchor rod rib comprises a steelwire cage and an anchor rod body set, wherein the steel wire cage comprises a first centering support, a second centering support and a steel wire mesh, the steel wire mesh is located between the first centering support and the second centering support, the anchor rod body set penetrates through the first centering support and the second centering support. According to the anti-floating anchor rod, the steel wire cage is adopted, connected with the anchor rod body and placed in a anchor rod hole, and the steel wire cage is placed at the designated position, required by design, of the top of the anchor rod, when the anchor rod is grouted, the steel wire cage, cement paste and the like are solidified into a whole and resist damage of external force together with rod body reinforcing steel bars, the anchoring grouting body is prevented from cracking and being damaged, the anti-cracking performance of the anchoring body of the anchor rod can be greatly enhanced, when a protective soil layer and redundant grouting bodies are cleaned, the solidified steel wire cage can control the head of the upper end of the anchor rod body not to crack or damage due to external force.
本发明涉及一种防止顶部锚固注浆体开裂的抗浮锚杆筋、抗浮锚杆，抗浮锚杆筋包括钢丝笼和锚杆杆体组；钢丝笼包括第一对中支架、第二对中支架以及钢丝网，钢丝网位于第一对中支架与第二对中支架之间；锚杆杆体组穿过第一对中支架和第二对中支架。本方案的抗浮锚杆由于采用一种钢丝笼，与锚杆杆体连接在一起，放入锚杆孔中，钢丝笼放置于设计要求的锚杆顶部指定位置；锚杆注浆时，钢丝笼与水泥浆等凝固为一个整体，与杆体钢筋一起抵抗外力的破坏，防止锚固注浆体开裂破损，能够大大增强锚杆锚固体的抗裂性能。清理保护土层和多余注浆体的时候，其凝固的钢丝笼能够控制锚杆体上端头部不受外力产生开裂或破损。
