Pressure type basalt fiber anchor rod
The invention discloses a pressure type basalt fiber anchor rod which comprises an anchor rod rib body. The anchor rod rib body comprises a free section and a fixed section; the fixed section extends into the grouting body; the bearing plate is arranged at the tail end, extending into the grouting body, of the fixed section, and the bearing plate is used for converting tensile force borne by the anchor rod rib body into pressure towards the free section to act on the grouting body; the sleeve is arranged outside the fixed section in a sleeving manner and is poured in the grouting body; the fixed section is movably arranged in the sleeve; the plugging piece is arranged on the fixed section in a sleeving manner and is used for preventing the grouting body from flowing into the sleeve; the bearing plate is mounted on the plugging piece; the stop piece is fixedly installed on the fixing section and used for limiting the bearing plate. The contact coupling relation between the anchor rod rib body and the grouting body is improved, and the stress mode of the grouting body is optimized; the method is simple in principle, convenient to operate and high in practicability, is mainly applied to permanent projects such as slope reinforcement and tunnel protection, and plays a role in effectively reducing potential safety hazards of the projects.
本发明公开一种压力型玄武岩纤维锚杆，包括锚杆筋体；锚杆筋体包括自由段和固定段；固定段伸入注浆体内；承载板设置于固定段伸入注浆体的末端，承载板用于将锚杆筋体的所受拉力转换成朝向自由段的压力而作用于注浆体上；套管套设于固定段外部且浇筑在注浆体内；固定段在套管内活动设置；封堵件套设于固定段上，用于防止注浆体流入到套管内；且承载板安装在封堵件上；止挡件固定安装在固定段，用于将承载板限位。本发明改善了锚杆筋体与注浆体间的接触耦合关系，优化了注浆体的受力方式；且本发明专利原理简单、操作方便，且实用性强，主要应用于边坡加固、隧道防护等永久性工程中，起到有效降低工程安全隐患的作用。
