Pressure type carbon fiber anchor cable device and anchoring method
The invention discloses a pressure type carbon fiber anchor cable device and an anchoring method, and relates to the technical field of anchor cable supporting, and the pressure type carbon fiber anchor cable device comprises an anchoring section, a free section and a tensioning section. The ground tensioning section carbon fiber bundle is anchored by adopting an anchoring assembly; the underground anchoring section steel strand bundle is anchored in a rock-soil body by adopting a bearing plate; the carbon fiber anchor cable body is provided with the PVC hard sleeve and the heat shrink tube to form an unbonded section; the steel strand anchor cable body forms an unbonded section by installing the plastic sheath and smearing grease; and the carbon fiber bundle is connected with the steel strand bundle through a combined anchorage device. The carbon fiber bundles are adopted to replace steel strand bundles, so that the corrosion resistance and durability of the anchor cable are improved; the carbon fiber bundle and the steel strand bundle are connected through the combined anchorage device, and the problem that the anchorage section of the carbon fiber anchor cable is poor in compressive shear resistance is solved.
本发明公开了一种压力型碳纤维锚索装置及锚固方法，涉及锚索支护技术领域，包括锚固段、自由段和张拉段。地上张拉段碳纤维束采用锚固组件锚固；地下锚固段钢绞线束采用承压板锚固于岩土体中；碳纤维锚索索体通过安装PVC硬套管和热缩管形成无粘结段；钢绞线锚索索体通过安装塑料护套和涂抹油脂形成无粘结段；碳纤维束与钢绞线束通过组合式锚具连接。采用碳纤维束代替钢绞线束提高了锚索的耐腐蚀性和耐久性；通过组合式锚具连接碳纤维束和钢绞线束，解决了碳纤维锚索锚固段抗压剪能力差的问题。
