The invention discloses an improved hollow grouting anchor rod. The improved hollow grouting anchor rod comprises an anchor rod head, the anchor rod head is fixedly connected with anchor rod head wing plates, open holes are formed in the inner sides of the anchor rod head wing plates, and the outer side of the anchor rod head is rotationally connected with a connecting pipe through a pin shaft. The connecting pipe, a rod body inserting pipe and a through hole are arranged, the rod body inserting pipe is a rod body inserting opening, and a screw thread combined with the threaded surface on the outer side of the rod body is arranged in the connecting pipe; a through hole allowing mortar to flow out is formed in the tail end, so that a mortar pouring opening of the rod body is fixed, the mortar can be poured into a designated position, and deviation is avoided; the anchor rod head wing plates and the open holes are arranged so that mortar bodies on the two sides of the anchor rod head can keep integrity, and the flatness of the surface filled with the mortar can be kept in an auxiliary mode; and the anchor rod head wing plates and the open holes can be matched with a soil body, anchoring force can be increased, and therefore the hollow grouting anchor rod is fixed.
本发明公开了一种改进型中空注浆锚杆,包括锚杆头,所述锚杆头与锚杆头翼板固定连接,所述锚杆头翼板内侧设置有开孔,所述锚杆头外侧与连接管通过销轴转动连接;通过设置连接管、杆体插入管和通孔,而杆体插入管为杆体插入口,且连接管内设置有与杆体外侧的螺纹面结合的丝扣,而最末端开有供砂浆流出的通孔,从而固定住杆体的灌入砂浆的口,使砂浆可灌入指定的位置,避免偏移,通过设置锚杆头翼板和开孔,有助于锚杆头两侧的砂浆体保持整体性,且还可辅助保持灌入砂浆的表面的平整性,还可通过锚杆头翼板、开孔与土体配合,增大锚固力,从而固定住中空注浆锚杆。
