Load dispersing type anti-floating anchor rod
The invention discloses a load dispersing type anti-floating anchor rod which comprises a pressure rib, a steel sleeve, a spiral rib, an anchoring body and a bearing plate, the pressure rib, the steel sleeve and the spiral rib are located on the same side of the bearing plate, the pressure rib and the steel sleeve are perpendicularly and fixedly connected with the bearing plate, the spiral rib is fixedly connected with the bearing plate, and the anchoring body is fixedly connected with the bearing plate. The central axis of a spiral body formed by the spiral ribs is perpendicular to the bearing plate. The steel sleeve is arranged on the outer side of the pressure rib, and the spiral rib is sleeved on the outer side of the steel sleeve; the anchoring body is poured on the outer side of the steel sleeve, and wrapping of the spiral rib and the bearing plate is completed. Under the simultaneous action of the pressure rib and the spiral rib, the stress distribution of the anti-floating anchor rod is more reasonable, the problem of local stress concentration at the load acting end of the anti-floating anchor rod is effectively solved, meanwhile, the friction force of an anchoring body of the anti-floating anchor rod and a soil body is secondarily distributed, the friction force transmission mode is changed, the anti-floating anchor rod is more uniform, and the anti-floating anchor rod is more stable. Therefore, the ultimate bearing capacity of the anti-floating anchor rod is improved.
本发明公开了一种荷载分散型抗浮锚杆，包括：压力筋、钢套管、螺旋筋、锚固体和承载板，所述压力筋、钢套管、螺旋筋位于承载板的同一侧，所述压力筋、钢套管与承载板垂直固定连接，所述螺旋筋与承载板固定连接，且所述螺旋筋形成的螺旋体的中轴线与所述承载板垂直设置；所述钢套管在压力筋外侧，螺旋筋套于钢套管外侧；所述锚固体浇筑于钢套管外侧，并完成螺旋筋和承载板包裹。本发明在压力筋和螺旋筋的同时作用下，使抗浮锚杆受力分布更加合理，有效解决抗浮锚杆荷载作用端出现局部应力集中的问题，同时对抗浮锚杆锚固体与土体的摩擦力进行了二次分配，改变摩擦力传递模式，使其更加均匀，从而提高抗浮锚杆的极限承载力。
