Grouting anchor rod drill bit and anti-floating anchor rod construction process
The invention relates to a grouting anchor rod drill bit and an anti-floating anchor rod construction technology, and relates to the technical field of anti-floating anchor rod construction. According to the grouting anchor rod drill bit, a connecting sleeve used for being connected with a drill rod is arranged on the upper surface of a base, and a cutting assembly used for cutting a soil layer or a gravel layer is arranged on the lower surface of the base; the cutting assembly comprises a plurality of cutting protrusions connected with the lower surface of the base, and all the corresponding cutting protrusions are sequentially arranged in the radial direction of the base. A discharging groove is formed in the peripheral wall of the base in the vertical direction in a penetrating mode. A grouting hole is downwards formed in the upper surface, located in the connecting sleeve, of the base, and a grout outlet hole is formed in the inner side wall of the grouting hole in a penetrating mode. In the process that the drill rod and the base are taken out of the anchor rod hole, grouting can be conducted in the anchor rod hole synchronously, so that the time of one-time grouting construction is shortened, and the construction efficiency of anti-floating anchor rod construction can be improved.
本申请涉及一种可注浆锚杆钻头及抗浮锚杆施工工艺，涉及抗浮锚杆施工技术领域。一种可注浆锚杆钻头，所述基座的上表面设置有用于与钻杆连接的连接套管，所述基座的下表面设置有用于切削土层或砂石层的切削组件；所述切削组件包括若干与基座的下表面相连的切削凸起，对应的全部的所述切削凸起沿基座的径向依次设置；所述基座的周壁沿上下方向贯穿设置有卸料槽；所述基座位于连接套管内的上表面向下设置有注浆孔，所述注浆孔的内侧壁贯穿设置有出浆孔。钻杆和基座由锚杆孔内取出的过程中，可同步向锚杆孔内注浆，以缩短一次注浆施工的时间，从而可提高抗浮锚杆施工的施工效率。
