Grouting anchor rod for layered slope of strip mine and construction method of grouting anchor rod
The invention discloses a grouting anchor rod for a layered side slope of a strip mine and a construction method of the grouting anchor rod, and relates to the technical field of side slope supporting. The grouting anchor rod comprises an anchor head, hollow anchor rod sections and a rubber pipe connecting section, the hollow anchor rod sections and the rubber pipe connecting section are distributed at intervals and communicated, the anchor head is arranged at the end of the hollow anchor rod section located at the head end, grouting is conducted on the end of the hollow anchor rod section located at the tail end, and grouting holes are formed in the side walls of the hollow anchor rod sections. During construction, the surface of the side slope is trimmed, so that the surface of the side slope is smooth; holes are drilled in the slope bottom and the slope surface in the direction perpendicular to the rock stratum, and the hole depth extends to the unexposed bedrock stratum; and a grouting anchor rod is installed in the hole, and grouting is conducted through the end of the hollow anchor rod section at the tail end. The grouting anchor rod is of a sectional type structure, the adjacent hollow anchor rod sections are connected through the rubber pipes, the rubber pipes have certain deformation resistance, and the steel strands or the iron chains are used for connection, so that the rubber pipes are prevented from being broken, small-amplitude slippage occurs on a side slope, pulling force is still provided, and the supporting effect is achieved.
本发明公开了一种用于露天矿层状边坡的注浆锚杆及其施工方法，涉及边坡支护技术领域。注浆锚杆包括锚头、中空锚杆段、胶管连接段，所述中空锚杆段与胶管连接段间隔分布并连通，位于首端的中空锚杆段端部设置有锚头，在位于尾端的中空锚杆段端部注浆，中空锚杆段侧壁上设置有注浆孔。施工时对边坡表面进行修整，使边坡表面平整；在坡底、坡面处垂直于岩层的方向钻孔，孔深度延伸到未揭露的基岩层；在孔内安装注浆锚杆，并通过尾端的中空锚杆段端部注浆。注浆锚杆采用分段式结构，且相邻中空锚杆段间使用胶管连接，胶管有一定的抗变形能力，再辅以钢绞线或铁链连接，避免胶管断裂，在边坡出现小幅滑移，仍提供拉力，起到支护作用。
