The invention discloses a self-adaptive large-deformation pre-stressed anchor rod. The self-adaptive large-deformation pre-stressed anchor rod comprises a first hollow rod body, a first baffle, a spring, a second baffle and a second hollow rod body, wherein the first hollow rod body and the second hollow rod body extend out of a sleeve, the first baffle, the spring and the second baffle are arranged in the sleeve, one end of the spring is connected with the first hollow rod body through the first baffle, and the other end of the spring is connected with the second hollow rod body through the second baffle; a pipeline penetrates through the inside of the spring, the pipeline communicates with the first hollow rod body and the second hollow rod body, and the second hollow rod body communicates with an air bag. According to the self-adaptive large-deformation pre-stressed anchor rod, the requirement for supporting strength can be met; under the condition of large deformation of surrounding rock, the supporting quality can be continuously guaranteed, the elongation of the anchor rod is improved, the length extension of the anchor rod is increased, the effective buffering and treatment effects can be achieved, and the safety of the supporting environment can be guaranteed; when a large impact load happens to the surrounding rock, the spring is gradually pulled open under the action of pulling force, a resin material keeps energy absorption, it is guaranteed that the anchor rod deforms slowly, a complete force transmission area is kept, and high efficiency and safety of the anchor rod are guaranteed.
本发明公开了一种自适应大变形预应力锚杆，包括中空杆体一、挡板一、弹簧、挡板二和中空杆体二，中空杆体一、中空杆体二伸出套筒，挡板一、弹簧、挡板二设置在套筒内，弹簧的一端通过挡板一与中空杆体一相连，另一端通过挡板二与中空杆体二相连，弹簧内穿过管道，管道与中空杆体一、中空杆体二相联通，中空杆体二与气囊相联通。本发明能够满足支护强度的要求，在围岩大变形情况下继续保证支护质量，提高锚杆延伸率，增大锚杆伸长量，能够起到有效的缓冲和治理作用，能够保障支护环境安全；当围岩发生较大冲击荷载时，在拉力的作用下，在弹簧将逐渐被拉开，树脂材料保持吸能，保证锚杆缓慢地变形，保持完整传力区域，确保锚杆的高效及安全。
