Recoverable rotary jet grouting expanded-head anchor cable and construction method
The invention discloses a recoverable rotary jet grouting expanded-head anchor cable and a construction method, the recoverable rotary jet grouting expanded-head anchor cable comprises a rotary jet grouting drill bit, a locking recovery device, a recoverable anchor cable, a drill rod, a protective sleeve and a prestressed steel strand, the rotary jet grouting drill bit and the recoverable anchor cable are installed on the locking recovery device, the locking recovery device is installed on the drill rod, and the prestressed steel strand is installed on the protective sleeve. The recoverable anchor cable is connected with the prestressed steel strand, the locking recovery device is connected with the protective sleeve, and the prestressed steel strand penetrates through the protective sleeve. The locking recovery device and the protective sleeve can form a closed space of the prestressed steel strands, the prestressed steel strands are not affected, the recovery reliability is improved, the unlocking recovery effect is better, and the locking recovery device is simple in structure, large in anchoring force, large in mass production and high in cost performance; locking and releasing of the recoverable anchor cable are simpler and more convenient, and manual recovery is convenient to operate and reliable.
本发明公开了一种可回收式旋喷扩大头锚索及施工方法，包括旋喷钻头、锁固回收装置、可回收锚索、钻杆、防护套管和预应力钢绞线，旋喷钻头和可回收锚索安装在锁固回收装置上，锁固回收装置安装在钻杆上，可回收锚索与预应力钢绞线连接，锁固回收装置与防护套管连接，预应力钢绞线穿过防护套管。本发明可以让锁固回收装置和防护套管形成预应力钢绞线的密闭空间，各股预应力钢绞线之间不受影响，提高回收的可靠性，其解锁回收效果更好，锁固回收装置的结构简单，锚固力大，大规模生产，性价比高；锁固和释放可回收锚索更加简便，人工回收便于操作和可靠。
