Rock anchor foundation
The invention relates to a rock anchor foundation. The rock anchor foundation comprises a rock layer; a plurality of deep holes are formed in the rock layer; an anchor rod is embedded in each deep hole; tapered hole bottoms are arranged at the bottoms of the deep holes; anchor rod expansion heads are positioned at the bottoms of the anchor rods, and are positioned at the tapered hole bottoms; thesurface of the rock layer is the ground plane; a foundation platform is arranged on the ground plane; a plurality of round holes are formed in the foundation platform; the upper ends of the anchor rods penetrate through the round holes; a plurality of barbed edges are arranged on the side wall of each anchor rod; the inclined angles between the barbed edges and the central axes of the anchor rodsare 22 degrees; and wave lines are also arranged on the side walls of the anchor rods, which is suitable for enhancing the tensile strength of the anchor rods. When the barbed edges are subjected to an upward pulling force, an upward pushing force is applied to concrete, and the concrete applies a downward reaction force on the barbed edges, so that the anchor rod is kept stable. When the wave line is subjected to vertical tension or a radial rotation force, the concrete gives a corresponding reaction force on the wave line to be kept stable. The rock anchor foundation has high resistance to tension and high stable structure.
本发明涉及一种岩石锚杆基础，包括岩石层，岩石层上设置有多个深孔，深孔的内部嵌入有锚杆，深孔的底部设置有锥形孔底，锚杆的底部设置有锚杆扩张头，锚杆扩张头位于锥形孔底处，岩石层的表面为地平面，地平面上设置有基础平台，基础平台上设置有多个圆孔，锚杆的上端穿过圆孔的内部，锚杆的侧壁上设置有若干倒刺棱，倒刺棱与锚杆的中轴线的夹角为22°。锚杆的侧壁上还设置有波浪线，适于增强锚杆的抗拉能力。倒刺棱在受到向上拉力时，会对混凝土施加一个向上的推力，混凝土给其一个向下的反作用力，促使锚杆保持稳固。波浪线在受到垂直拉力或者径向旋转力时混凝土会给其一个相应的反作用力使其保持稳定。该岩石锚杆基础抗拉能力强、结构稳定。
