Arc-shaped anchor rod construction method
The invention discloses an arc-shaped anchor rod construction method and belongs to the technical field of building construction. The method comprises the following steps: determining a drilling position around an obstacle according to design requirements; driving an arc-shaped anchor rod by a drill bit to drill into a drill hole; washing the residual soil debris in the drill hole by using pressurized water; installing an anchor cable in the drill hole; conducting grouting on the drill hole; and tensioning and locking the anchor cable on a waist beam. According to the arc-shaped anchor rod construction method provided by the invention, the detectable direction-variable drill bit can automatically bypass the obstacle for drilling, the designed working line is restored after the obstacle isbypassed, the arc-shaped drill hole is formed to avoid the obstacle, and the arc-shaped anchor rod is formed. The arc-shaped anchor rod can avoid obstacles and overcome adverse effects of complex geology, stress of the arc-shaped anchor rod is greatly increased, construction quality of the anchor rod is guaranteed, and safety and reliability of foundation pit supports and surrounding buildings areguaranteed.
一种弧线形锚杆施工方法，属于建筑施工技术领域，所述方法包括步骤：根据设计要求在障碍物周围确定钻孔位置；通过钻头带动弧线形锚杆钻进所述钻孔中；压水冲洗残留在所述钻孔中的土屑；向所述钻孔中安装锚索；向所述钻孔中注浆；在腰梁上张拉与锁定所述锚索。本申请提供的一种弧线形锚杆施工方法，采用可探测可变向钻头即可自行绕开障碍物进行钻进，绕开障碍物后又恢复到之前设计工作线路，并形成弧线型钻孔避开障碍物，形成弧线型的锚杆；该弧线型锚杆不仅能避开障碍物，克服复杂地质的不利影响，而且其受力大大增加，确保了锚杆施工质量，保证了基坑支护和周围建筑物安全可靠。
