Anti-floating anchor rod for constructional engineering

The utility model relates to an anti-floating anchor rod for constructional engineering. The anti-floating anchor rod comprises a rod body, a grouting cavity is formed in the rod body and penetrates through the top end of the rod body, a plurality of overflow holes are formed in the outer surface of the rod body and communicated with the grouting cavity, a positioning ring is arranged in the middle of the rod body, the inner diameter of the positioning ring is larger than the diameter of the rod body, and the positioning ring is connected with the rod body through a plurality of connecting ribs. Aiming at the defects in the prior art, the utility model aims to provide the anti-floating anchor rod for constructional engineering. The method is used for solving the problem that due to the fact that an anti-floating anchor rod is not located in the center of a drilled hole, grouting is not uniform, and the pile forming stability is reduced. 本实用新型涉及一种建筑工程抗浮锚杆，包括杆体；所述杆体内设有注浆腔，所述注浆腔贯穿杆体顶端，所述杆体外表面设有多个溢流孔，多个溢流孔均连通注浆腔，
