Recyclable anchor cable
The recoverable anchor cable comprises a cable body, concrete and a yielding anchorage device, and the cable body comprises two or more prestressed tendons distributed in the circumferential direction; the yielding anchorage device is embedded in concrete and is used for anchoring the prestressed tendons; each prestressed tendon sequentially comprises a bearing section, a transition section and a bonding section; the bearing section is anchored on concrete through a yielding anchorage device; the transition section comprises a sleeve wrapping the outer ring of the prestressed tendon, and the outer wall of the sleeve is fixedly connected with concrete; and the prestressed tendons of the bonding section are directly and fixedly connected with the concrete. According to the recoverable anchor cable, the prestressed tendons can be prevented from being broken or falling off, the instant impact force released by the force value of the prestressed tendons is reduced, the instant impact force released by the cohesive force of the prestressed tendons in the recovery process is reduced, and the instant impact force released by the cohesive force of the prestressed tendons is reduced.
本发明公开了一种可回收型锚索，包括索体、混凝土及让压锚具，索体包括沿圆周方向分布的两根以上预应力筋；让压锚具埋设于混凝土中，用于锚固预应力筋；所述预应力筋依次包括承载段、过渡段和粘结段；所述承载段通过让压锚具锚固于混凝土；所述过渡段包括包裹于预应力筋外环的套管，所述套管的外壁与混凝土固结；所述粘结段的预应力筋直接与混凝土固结。本发明公开的一种可回收型锚索，能够防止预应力筋断裂或脱落，削减预应力筋力值释放的瞬间冲击力，减小回收过程中预应力筋粘结力释放的瞬间冲击力，削减预应力筋粘结力释放的瞬间冲击力。
