Self-adaptive gradient resistance-increasing yielding anchor rod
The self-adaptive gradient resistance-increasing yielding anchor rod comprises a nut, a tray and a rod body, and the nut and the tray are arranged at one end of the rod body; the device is characterized in that a yielding device is arranged outside the rod body, the yielding device is a hollow cylinder, and the yielding device penetrates through the tray and is in threaded connection with the nut; the pressing device is a hollow cylinder and is mounted in the surrounding rock close to the free side; the nut and the tray are mounted outside the surrounding rock; the self-adaptive yielding device has the advantages that self-adaptive yielding quantity can be generated when the surrounding rock has creep deformation or expansion deformation, the self-adaptive yielding resistance can be realized according to deformation conditions, the yielding resistance can be increased in a graded manner along with graded release of deformation, and a good supporting control effect on a soft rock large-deformation tunnel is achieved.
本发明公开了一种自适应梯度增阻让压锚杆，包括螺母、托盘和杆体，所述的杆体的一端设螺母和托盘；其特点是，所述的杆体外设让压装置，所述的让压装置为空心圆柱体，所述的让压装置穿过托盘与螺母螺纹连接；压装置为空心圆柱体，安装于围岩内部靠近临空侧；螺母和托盘安装于围岩外侧；可以在围岩发生蠕变变形或膨胀变形时发生自适应让压量，并根据变形情况自适应让压阻力，随着变形的分次释放，能够分级增加让压阻力，对软岩大变形隧道具有很好的支护控制作用。
