Composite anchoring system for fiber reinforced composite inhaul cable and preparation method
The invention discloses a composite anchoring system for a fiber reinforced composite inhaul cable and a preparation method, and belongs to the technical field of cable anchoring structures of civil engineering. The method comprises the following steps that firstly, a fiber reinforced composite parallel rod cable and a high-temperature-resistant bonding medium are prefabricated into a cylindrical stress whole through a silica gel mold; and clamping the cylindrical stressed whole body by using a clamping piece, and inserting into a steel anchor cylinder to complete anchoring, and applying longitudinal pre-pressure to the clamping piece from the free end of the anchorage device, so that a static load test can be carried out. The problems that according to a traditional friction type anchorage device, a traditional bonding type anchorage device and a traditional combined anchorage device, local shear fracture occurs, the cable anchor slippage amount is large, a cable body fails to be pulled out, and the heat stability of the anchorage device is poor are solved. The device has the advantages of being high in anchoring efficiency, small in cable anchor slippage amount and small in size.
本发明公开一种用于纤维增强复材拉索的复合型锚固系统及制备方法，属于土木工程索锚结构技术领域，方法如下：首先通过硅胶模具将纤维增强复合材料平行杆索与耐高温黏结介质预制成圆柱状受力整体，再用夹片夹持圆柱状受力整体后插入钢锚筒完成锚固，从锚具自由端向夹片施加纵向预压力即可进行静载测试。本发明解决了传统的摩擦型锚具、粘结型锚具及组合型锚具存在的局部剪切断裂、索锚滑移量大、索体拔出失效、锚具热稳定性差的问题；具有锚固效率高、索锚滑移量小且尺寸较小的优点。
