Self-adaptive yielding anchor rod device and construction method
The self-adaptive yielding anchor rod device comprises an anchor rod body, a tray, a yielding device and a pre-tightening nut, the tray, the yielding device and the pre-tightening nut are arranged on the threaded section of the top of the anchor rod body in a sleeving mode from bottom to top, high-strength base plates are arranged on the upper side and the lower side of the yielding device correspondingly, and the yielding device comprises a replaceable steel pipe with through holes evenly distributed in the circumference; a damping ring is tightly attached to the inner wall of the yielding device, and an anti-corrosion coating is brushed on the outer wall. The invention further provides a self-adaptive anchor rod construction method which comprises the following steps that A, firstly, a hole is drilled through the drilling tool, and the anchor rod body is placed in the drilled hole; b, an anchor rod body is fixed, and then a yielding device is selected according to impact force generated by rock deformation; c, a tray and a yielding device are sequentially installed at the thread position of the anchor rod body from top to bottom; and D, the yielding device is subjected to compression deformation after absorbing impact force to achieve yielding displacement. The method has the advantages of being good in supporting effect, wide in applicability, good in damping effect, simple in construction step, easy to operate and the like.
本发明公开了一种自适应让压锚杆装置，包括锚杆杆体和从下往上套装在锚杆杆体顶部螺纹段的托盘、让压装置、预紧螺母，让压装置的上下两侧均配备有高强垫板，让压装置包括环周均布设有通孔的可更换钢管，让压装置内壁紧贴有减震环、外壁刷有防腐蚀涂层。本发明还提供一种自适应锚杆施工方法，包括以下步骤：步骤A、先通过钻孔工具钻孔，将锚杆杆体置入钻孔内；步骤B、固定锚杆杆体，然后根据岩体变形产生冲击力选取让压装置；步骤C、先后将托盘、让压装置从上往下安装在锚杆杆体的螺纹处；步骤D、让压装置吸收冲击力后发生压缩变形实现让压位移，具有支护效果好、适用性广、减震效果好、施工步骤简单易操作等优点。
