Shearing unlocking type recoverable pre-stressed anchor cable and construction technology thereof
The invention discloses a shear unlocking type recoverable pre-stressed anchor cable and a construction technology thereof.The shear unlocking type recoverable pre-stressed anchor cable comprises a protective side shell, a protective bottom shell and a shear unlocking device, the protective side shell is of a circular tube structure, the bottom end of the protective side shell and the protective bottom shell are installed, a limiting groove is formed in the protective bottom shell, the top end of the limiting groove is flush with the bottom end of a positioning plate, and the positioning plate is fixed through three positioning bolts; a bearing table in the protection side shell and a limiting plate are installed in the vertical direction, a conical clamp with a circular truncated cone groove in the bearing table and arranged at equal intervals in an annular mode provides stable installation, the circular truncated cone groove of the bearing table is matched with a limiting ring to contract the conical clamp, and the conical clamp is of a three-petal structure so that steel strands of different diameters can be collected conveniently. The invention further provides a construction technology of the rotary unlocking type recoverable pre-stressed anchor cable. The rotary unlocking type recoverable pre-stressed anchor cable has the advantages that the structure is simple, installation on a construction site is convenient and fast, a plurality of steel strands can be recovered at the same time, and the rotary unlocking type recoverable pre-stressed anchor cable has high economical efficiency, operability and environmental friendliness.
本发明公开了一种剪切解锁式可回收预应力锚索及其施工工艺，包括：保护侧壳，其设置为圆管状结构，所述保护侧壳底端与保护底壳安装，且保护底壳内部设置有限位槽，所述限位槽顶端与定位板底端平齐，且定位板由3个定位螺栓进行固定；保护侧壳内部的承载台与限位板呈垂直方向安装，位于承载台内部的圆台凹槽呈环形等距设置的锥形夹具提供稳定安装，承载台的圆台凹槽与限位环配合对锥形夹具收缩，锥形夹具为三瓣结构便于对不同直径的钢绞线进行收束。本发明还提出了上述旋转解锁式可回收预应力锚索的施工工艺，具有结构简单、施工现场安装便捷、可实现多根钢绞线同时回收，具有较大的经济性，可操作性、环保性。
