Slow-release resistance-increasing yielding anchor rod and method
The invention relates to a slow-release resistance-increasing yielding anchor rod and a method. The slow-release resistance-increasing yielding anchor rod comprises a sleeve, wherein an inner cavity in the axis direction of the sleeve is formed in the sleeve, and one end of the sleeve is blocked; a shaft rod penetrates through the inner cavity of the sleeve, one end of the shaft rod extends into the inner cavity of the sleeve, and a connecting piece is mounted at the other end of the shaft rod and used for being connected with a rock wall. A gas chamber is formed in the inner cavity of the sleeve, and a piston is arranged in a set position of the shaft rod, so that the gas chamber, the shaft rod and the piston define a closed gas space; and compressed gas can be injected into the gas spaceand used for providing resistance when the shaft rod slides in the direction away from the sleeve. The piston can slide in the axis direction of the shaft rod, so that compression or expansion of gasin the compressed space is realized.
本发明涉及一种缓释增阻让压锚杆及方法，包括套筒，所述套筒中具有沿自身轴线方向的内腔，所述套筒的一端封堵；所述套筒的内腔中穿设有轴杆，所述轴杆的一端伸入套筒的内腔中，另一端安装有连接件，所述连接件用于连接岩壁。所述套筒的内腔中设有气体腔室，所述轴杆的设定位置设置有活塞，以使得气体腔室、轴杆、活塞围合形成密闭的气体空间；所述气体空间中能够注入压缩气体，所述压缩气体用于提供轴杆向着远离套筒方向滑动时的阻力。所述活塞能够沿轴杆的轴线方向滑动，以实现压缩空间中气体的压缩或扩张。
