Drilling, bolting and grouting integrated self-adaptive anchor rod and open pit coal mine slope reinforcing method
The invention discloses a drilling, bolting and grouting integrated self-adaptive anchor rod and an open pit coal mine slope reinforcing method, and relates to the field of mining equipment of open pit coal mines. The device is simple in structure, convenient to operate and good in anchoring effect, rapid drilling and grouting are achieved, and construction efficiency and anchoring quality are improved. The self-adaptive anchor rod comprises a plurality of anchor rod units which are connected end to end and internally communicated, each anchor rod unit comprises a grouting section and a control section, each control section is provided with a center hole with the inner diameter smaller than that of the corresponding grouting section, the grouting sections in the adjacent anchor rod units are communicated through the center holes, and therefore a Venturi tube structure is formed. Power can be improved for the grouting section; a plurality of grouting holes are formed in the circumferential direction of the side wall of the grouting section; a control valve is arranged in the control section and used for controlling grouting of the grouting section in the anchor rod unit to be finished. When a plurality of anchor rod units are implanted into a drill hole, a bead-string-shaped anchoring body is formed through grouting, and the anchoring effect can be remarkably improved.
本发明公开了一种钻锚注一体化的自适应锚杆与露天煤矿边坡加固方法，涉及露天煤矿的开采设备领域。其结构简单、操作方便且锚固效果好，实现了快速钻进和注浆，提高了施工效率和锚固质量。所述自适应锚杆包括首尾相接且内部保持连通的多个锚杆单元，每个锚杆单元则包括注浆段以及控制段，所述控制段具有内径小于注浆段内径的中心孔，相邻锚杆单元中的注浆段通过该中心孔保持连通，从而形成文丘里管结构，可为注浆段提高动力；在所述注浆段的侧壁的周向上开设有多个注浆孔；控制段的内部则设有控制阀，用于控制该锚杆单元中注浆段的注浆结束。本发明中多个锚杆单元植入钻孔时，通过注浆形成串珠状锚固体，可以显著提高锚固效果。
