Obstacle clearing method for grouting pile
The invention belongs to the field of building construction, and particularly relates to an obstacle clearing method for a grouting pile. The obstacle clearing method comprises the following steps: S1of making preparation of obstacle clearing operation: equipment assembly, hole center measuring, steel plate spreading and full-revolving drilling machine positioning; S2 of utilizing a locking device to lock the grouting pile, twisting the locking device by the full-revolving drilling machine, twisting off the grouting pile in sections, and clearing the grouting pile; and S3 of using an obstacleclearer to clear sediments in a pile hole, crushing the sediments by a diamond drill bit in a rotary process of the obstacle clearer, and transferring out the sediments through a screw inside a protective barrel. The obstacle clearing method for the grouting pile disclosed by the invention is suitable for a condition that a pile is buried deeply, also can clear the sediments on the bottom of thepile hole, is high in clearing efficiency and is wide in range of application.
本发明属于建筑施工领域，尤其涉及一种灌注桩清障方法，S1.清障作业的准备：设备拼装、测定孔位中心、铺设钢板、全回转钻机定位；S2.利用锁紧装置将灌注桩锁紧，全回转钻机扭转锁紧装置，将灌注桩分段拧断，然后清除灌注桩；S3.使用清障器清除桩孔的沉渣，清障器旋转的过程中，金刚钻头将沉渣打碎，通过护筒内部的螺杆将沉渣运送出去；上述灌注桩清障方法，适用于桩埋置较深的情况，同时能够一并清除桩孔底部的沉渣，清除效率高，使用范围广。
