The utility model discloses a hollow basalt fiber anchor rod structure adapting to surrounding rock deformation, which is specifically characterized in that a basalt fiber rod body is hollow and externally provided with threads, an anchor head is arranged at the head of the basalt fiber rod body, and the tail of the basalt fiber rod body sequentially penetrates through a stop-grouting plug, a base plate, a constant-resistance extrusion sleeve and a conical barrel. And finally, nuts are used for fixing. The structure can effectively adapt to deformation of surrounding rocks. 本实用新型公开了一种适应围岩变形的中空玄武岩纤维锚杆结构，中空玄武岩纤维锚杆结构具体为：玄武岩纤维杆体中空外带螺纹，玄武岩纤维杆体头部设有锚头，玄武岩纤维杆体尾部依次穿过止浆塞、垫板、恒阻挤压套筒、锥形桶，最后采用螺母固定。本实用新型结构能有效适应围岩的变形。
