Anchor rod construction method of rock anchor rod foundation
The invention discloses an anchor rod construction method of a rock anchor rod foundation. The anchor rod construction method comprises the following steps that S1, a foundation pit is excavated; s2, binding construction of upper structural steel bars; s3, a protection pipe is additionally installed and positioned; s4, the reinforcement cage is positioned; s5, foundation pit backfilling is conducted; s6, anchor rod hole forming is completed; s7, a hollow anchor rod is placed in the anchor hole; s8, anchoring body pouring; s9, when an anchoring body is poured, an anchoring agent is injected from the top of the hollow anchor rod through the hollow anchor rod; s10, after construction is finished, the protection pipe is removed, and the foundation shape is restored; the step of installing the protective pipe is added, the construction quality is effectively improved, and long-time exposure of the hole wall is avoided; secondly, the hollow anchor rod is used, pit descending operation during construction can be avoided, blockage can be avoided, and then the operation efficiency and safety are improved; the thread-shaped protective pipe is selected, and the pulling device is additionally arranged, so that more labor is saved when the protective pipe is removed, and poured materials cannot be damaged.
本发明公开一种岩石锚杆基础的锚杆施工方法，包括以下步骤：S1、挖掘基坑；S2、上部结构钢筋的绑扎施工；S3、加装护管并对其进行定位；S4、对钢筋笼进行定位；S5、进行基坑回填；S6、完成锚杆成孔；S7、在锚孔中下放中空锚杆；S8、锚固体浇筑；S9、锚固体浇筑时，锚固剂通过中空锚杆自其顶部注入；S10、施工结束后移除护管，恢复基础形状；增加了安装护管的步骤，有效提高了施工质量，并且避免了孔壁长时间的暴露；其次，使用中空锚杆，可以避免在施工的时候下坑作业，还可以避免堵塞，进而提高了作业效率和安全性；选用了螺纹状的护管并增设起拔装置，更便于在移除护管时更省力且不会破坏已浇筑好的材料。
