The invention discloses an anti-floating anchor rod with telescopic heads and a construction method, and belongs to the field of building foundation engineering. An anchor rod main body structure comprises a steel pipe with the outer surface engraved with grains, anchoring steel bars welded on the end part of the steel pipe and a round steel plate with holes for plugging the steel pipe, a cross rod with a fixing function is welded on a central rod, the central rod penetrates through a hole for plugging the round steel plate and is connected with inclined supporting rods through hinged devices,the inclined supporting rods are connected with the telescopic heads through the hinged devices, the telescopic heads are placed in holes of an anchor rod body, and a sleeve is arranged on the central rod in a sleeving mode and connected with the inclined supporting rods through springs. The center rod is pushed downwards, the center rod drives the inclined supporting rods to push the telescopicheads to the periphery through the hinged devices, and the telescopic heads are inserted into the soil body outwards through the holes of the anchor rod body, so that the friction contact area betweenthe anti-floating anchor rod and the soil body can be increased, the anti-floating anchor rod has a certain pressure contact surface with the soil body, and the anti-pulling capacity of the anti-floating anchor rod can be greatly improved.
发明公开了一种具有伸缩头的抗浮锚杆及施工方法，属于建筑基础工程领域。本发明的锚杆主体结构为外表面刻有纹路的钢管，焊在钢管端部的锚固钢筋，封堵钢管的带孔圆钢板，中心杆焊有起固定作用的十字杆，中心杆穿过封堵圆钢板的孔洞通过铰接装置与斜撑杆相连接，斜撑杆利用铰接装置与伸缩头相接，伸缩头放置在锚杆体的孔洞中，套管套在中心杆上，并用弹簧与斜撑杆相连接。向下推动中心杆，中心杆则通过铰接装置带动斜撑杆向四周推动伸缩头，伸缩头通过锚杆体的孔洞向外插入土体，从而可以增大抗浮锚杆与土体的摩擦力接触面积，并且与土体有一定的压力接触面，可以极大的提高抗浮锚杆的抗拔能力。
