Advanced pre-reinforcement structure for strip mine rock bedding slope treatment
The invention discloses an advanced pre-reinforcing structure for strip mine rock bedding side slope treatment, a pile top groove (1) is positioned right above a subsurface sliding surface (5) at the lower part of a side slope platform, and a concrete plate (2) is poured in the pile top groove (1); 2-4 rows of seamless steel pipes (3) are installed in side slope platform drill holes and penetrate through the subsurface sliding face (5), slurry holes (7) are formed in the pipe walls of the seamless steel pipes (3), and the whole seamless steel pipes (3) are filled with grouting concrete which is filled into the subsurface sliding face (5) through the slurry holes (7) to form interlayer concrete (6). The influence of stress disturbance in the surface mine slope leaning process can be effectively reduced, and meanwhile the stability of a slope leaning side slope can be remarkably improved through the supporting and retaining effect of the pile-rock composite structure and interlayer concrete filled into a weak structural face through the slurry holes of the steel pipe body; and the reinforcing structure embedded under the road surface does not affect normal passing of the step road surface, and the use efficiency of the step road surface can be effectively improved.
本发明公开了一种用于露天矿岩质顺层边坡治理的超前预加固结构，桩顶槽(1)位于边坡平台下部的潜滑面(5)的正上方，桩顶槽(1)内浇筑混凝土板(2)；2～4排无缝钢管(3)安装在边坡平台钻孔内并穿过潜滑面(5)，无缝钢管(3)的管壁上设有浆孔(7)，注浆混凝土充满整个无缝钢管(3)并通过浆孔(7)充填进潜滑面(5)形成层间混凝土(6)。本发明能够有效地减小在露天矿山靠帮过程中的应力扰动的影响，同时其桩‑岩复合结构的支挡作用和通过钢管管身的浆孔充填进软弱结构面的层间混凝土，能够显著地提高靠帮边坡的稳定性，并且本发明嵌于路面之下的加固结构不影响台阶路面的正常通行，能够有效地提高台阶路面使用效率。
