The invention discloses a prestress bag type expansion anchor rod and belongs to the technical field of anti-floating anchor rods, the prestress bag type expansion anchor rod comprises an anchor rod body and an anchoring section, a plurality of arc-shaped plates are arranged on the peripheral face of the anchor rod body, a driving ring is arranged on the periphery of the anchor rod body in a sleeving mode, and a plurality of driving rods are hinged to the periphery of the driving ring; the ends, away from the driving rings, of the driving rods are hinged to the inner walls of the arc-shaped plates. First threads are arranged on the peripheral face of the anchor rod body, the periphery of the anchor rod body is sleeved with a driving sleeve, the driving sleeve is rotationally connected with the driving ring, and the driving sleeve is in threaded transmission fit with the anchor rod body through the first threads; an abutting groove is formed in the top face of the anchoring section, an abutting block is installed on the anchoring section in a sliding mode in the vertical direction through the abutting groove, and a limiting groove where the abutting block is inserted is formed in the bottom face of the anchor rod body. The possibility that the inner wall of the anchor hole collapses due to the fact that the arc-shaped plates are in contact with the inner wall of the anchor hole after being opened can be reduced.
本申请公开了一种预应力囊式扩体锚杆，属于抗浮锚杆的技术领域，其，包括锚杆杆体及锚固段，锚杆杆体的外周面设置有若干个弧形板，锚杆杆体的外周套设有驱动环，驱动环的外周铰接有若干个驱动杆，驱动杆远离驱动环的一端与弧形板的内壁相铰接；锚杆杆体的外周面设置有螺纹一，锚杆杆体的外周套设有驱动套筒，驱动套筒与驱动环转动连接，驱动套筒通过螺纹一与锚杆杆体螺纹传动配合；锚固段的顶面开设有抵接槽，锚固段通过抵接槽沿竖向滑移安装有抵接块，锚杆杆体的底面开设有用于插设抵接块的限位槽。本申请能够减少弧形板张开后与锚孔内壁相触碰而导致锚孔内壁发生坍塌的可能性。
