Self-tapping grouting counter-force anchor
The invention provides a self-tapping grouting counter-force anchor. The self-tapping grouting counter-force anchor comprises an anchor head, a thrust device and an injection pipe; the injection pipe is a full-length hollow pipe; the anchor head comprises a drill bit and a sliding groove linkage mechanism, the drill bit sleeves at the front end of the injection pipe, a sliding way is arranged on the side wall of a sleeve of the drill bit, and the sliding groove linkage mechanism is arranged in the sliding way and can slide in the sliding way in a retractable mode; the thrust device comprises a thrust rod and an adjusting nut, the thrust rod sleeves the middle of the injection pipe, the front end of the thrust rod abuts against the tail end of the sliding groove linkage mechanism, the adjusting nut is connected to the injection pipe in a threaded mode, and the front end of the adjusting nut abuts against the rear side of the thrust rod. The self-tapping grouting counter-force anchor can automatically drive discharging of mud scraps to complete drilling and filling agent injection, so that the counter-force anchor is rapidly built, large-scale machinery cooperation is not needed, and the self-tapping grouting counter-force anchor is simple and practical.
本发明提供一种自攻灌浆反力锚，包括：锚头、推力装置和注入管；所述注入管为通长的空心管；所述锚头包括钻头、和滑槽联动机构，所述钻头套设在所述注入管前端，所述钻头的套管侧壁设有滑道，所述滑槽联动机构安置在滑道内并可在滑道内伸缩滑动；所述推力装置包括推力杆和调整螺母，所述推力杆套设在所述注入管中部，推力杆的前端抵接在所述滑槽联动机构尾端，所述调整螺母螺纹连接在所述注入管上，调整螺母的前端抵接在所述推力杆的后侧。本申请的反力锚可自行带动泥屑的排出完成钻孔及填充剂注入，从而快速建立反力锚，无需大型机械配合，简单实用。
