Yield anchor cable
The yield anchor cable comprises a steel strand, a base plate, an anchorage device, a sleeve, a deformation sleeve, a locking sleeve and a plug, and the locking sleeve is a frustum-shaped locking sleeve with a large end and a small end; the plug is connected with one end of the sleeve to form a closed end; an annular limiting ring is fixed to the other end of the plug, the other end of the steel strand extends into the sleeve from the limiting ring, the section, extending into the sleeve, of the steel strand is sequentially sleeved with a deformation sleeve and a locking sleeve, one end of the deformation sleeve abuts against the limiting ring, the outer side of the conical top of the locking sleeve is inserted into the other end of the deformation sleeve, and the other end of the locking sleeve abuts against the plug. The sleeve, the deformation sleeve, the locking sleeve and the plug are arranged at the front end of the anchor rod, when surrounding rock deforms, the steel strand pulls the locking sleeve to move outwards, the locking sleeve is inserted into the deformation sleeve, the deformation sleeve is propped open to abut against the inner wall of the sleeve, the steel strand is attached to the sleeve through the locking sleeve and the deformation sleeve all the time, and the resistance of the anchor cable to the surrounding rock is constant; the requirement of large deformation of surrounding rock can be met.
本发明公开了一种屈服锚索，包括钢绞线、垫板、锚具、套筒、变形套、锁紧套和堵头，锁紧套为一端大一端小的锥台形锁紧套；堵头与套筒的一端连接，形成封闭端；堵头的另一端固定有环形的限位环，钢绞线的另一端从限位环伸入套筒内，在钢绞线伸入套筒内的一段上依次套设有变形套、锁紧套，变形套的一端与限位环抵接，锁紧套的锥顶外侧插入变形套的另一端内部，锁紧套的另一端与堵头抵接。本发明通过在锚杆前端设置套筒、变形套、锁紧套和堵头，当围岩变形时，钢绞线拉动锁紧套向外移动，锁紧套插入变形套内，将变形套撑开抵接在套筒内壁，钢绞线始终与套筒通过锁紧套和变形套贴紧，锚索给予围岩的阻力恒定，能够满足围岩大变形的需要。
