Anchor rod suitable for swelling-shrinkage deformation of expansive soil
The invention discloses an anchor rod suitable for swelling-shrinkage deformation of expansive soil. The anchor rod comprises an anchorage device, a free section and an anchoring section from top to bottom, wherein the anchorage device comprises a supporting plate support, an anchor head piston sleeve, a magnetic sliding anchor head, springs, a piston sleeve top magnet, a piston sleeve bottom magnet, an upper end portion of a rod body and a nut, the free section comprises a middle portion of the rod body, a plastic sleeve and a stop-grouting plug, and the anchoring section comprises a lower end portion of the rod body, a cement mortar portion and a bearing body; and the magnetic sliding anchor head capable of sliding up and down is arranged inside the anchor head piston sleeve, the pistonsleeve top magnet and the piston sleeve bottom magnet are further arranged above and below the magnetic sliding anchor head, and repulsive force exists between the lower end face of the piston sleevetop magnet and the upper end face of the magnetic sliding anchor head and between the lower end face of the magnetic sliding anchor head and the upper end face of the piston sleeve bottom magnet. Theanchor rod uses the design of the magnets and the springs ingeniously, and achieves the effects of capable of anchoring the expansive soil and capable of adapting to swelling-shrinkage deformation ofthe expansive soil.
一种适用于膨胀土胀缩变形的锚杆，包括从上至下的锚具、自由段和锚固段，锚具包括托板支座、锚头活塞套管、磁性滑动锚头、弹簧、活塞套顶部磁铁、活塞套底部磁铁、杆体的上端部分、螺母，自由段包括杆体的中间部分、塑性套管和止浆塞，锚固段包括杆体的下端部分、水泥砂浆部分和承载体；锚头活塞套管内部设有能上下滑动的磁性滑动锚头，磁性滑动锚头的上方和下方还分别设置有活塞套顶部磁铁和活塞套底部磁铁，活塞套顶部磁铁的下端面和磁性滑动锚头的上端面之间以及磁性滑动锚头的下端面和活塞套底部磁铁的上端面之间均存在斥力；本发明巧妙利用了磁铁及弹簧的设计，起到了既能完成对膨胀土的锚固又能适应膨胀土胀缩变形的作用。
