Grouting-free low-retraction anchor cable system
The invention provides a grouting-free low-retraction anchor cable system which comprises an anchorage device, a cable body and a thermal shrinkage sleeve, the anchorage device comprises a tensioning end anchorage device and a fixed end anchorage device, and the cable body comprises a protective sleeve, anti-corrosion grease and a steel strand. One end of the cable body is provided with a tensioning end anchorage device, and the other end of the cable body can be provided with a fixed end anchorage device or a tensioning end anchorage device. The tensioning end anchorage device comprises an anchor head, a force bearing nut and a steel base plate. A first inner hole is drilled in the end face of one end of the anchor head, and the head of the cable body is inserted into the first inner hole and connected with the first inner hole in a fastened mode. The method has the beneficial effects that the problems that the retraction value of a conventional anchorage device is too large and hole channel grouting is not compact are solved, and the problem caused by the fact that a prestressed steel bar is prone to fracture during tensioning is also avoided.
本发明提供了一种免灌浆低回缩锚索系统，包括锚具、索体和热缩套，所述锚具包含张拉端锚具和固定端锚具，所述索体包括保护套、防腐油脂、钢绞线。索体一端安装有张拉端锚具，另一端可安装固定端锚具，也可安装张拉端锚具。所述张拉端锚具包含锚头、承力螺母和钢垫板。所述锚头的一端端面钻有第一内孔，所述索体的头部插入所述第一内孔并实行紧固连接。本发明的有益效果是：解决了常规锚具回缩值过大和孔道灌浆不密实的问题，也避免了使用预应力钢棒张拉易断裂引发的问题。
