Avoidance type anti-seepage curtain structure encountering filling soil karst cave in karst region
The invention discloses an avoidance type anti-seepage curtain structure in a karst region encountering a filling soil karst cave, which comprises an upper layer grouting cave, a middle layer grouting cave and a lower layer grouting cave which are arranged in an area outside the filling soil karst cave, and the upper layer grouting cave is drilled and grouted downwards to form a first vertical curtain; the middle-layer grouting hole is used for drilling and grouting upstream to form a first horizontal curtain and drilling and grouting downwards to form a second vertical curtain, the lower-layer grouting hole is used for drilling and grouting around to form a second horizontal curtain or an annular curtain and drilling and grouting downwards to form a third vertical curtain, the first horizontal curtain is in lap joint with the first vertical curtain, and the second horizontal curtain is in lap joint with the second vertical curtain. The second horizontal curtain or the annular curtain is in lap joint with the second vertical curtain. The method is convenient to construct, low in investment, short in construction period and high in construction safety; according to the curtain formed by drilling and grouting in the grouting hole in the rock mass, the anti-seepage material is uniform, the type is single, lap joint of soil mass anti-seepage and rock mass anti-seepage is avoided, and the anti-seepage effect is improved.
本发明公开了一种喀斯特地区遇到充填土溶洞的避让式防渗帷幕结构，包括设置在充填土溶洞之外区域的上层灌浆洞、中层灌浆洞和下层灌浆洞，上层灌浆洞向下钻孔灌浆形成第一竖向帷幕，中层灌浆洞向上游钻孔灌浆形成第一水平帷幕、以及向下钻孔灌浆形成第二竖向帷幕，下层灌浆洞向周围钻孔灌浆形成第二水平帷幕或环形帷幕、以及向下钻孔灌浆形成第三竖向帷幕，其中，第一水平帷幕与第一竖向帷幕搭接，第二水平帷幕或环形帷幕与第二竖向帷幕搭接。本发明施工便利、投资低、工期短，施工安全性高；通过在上述位于岩体中的灌浆洞钻孔灌浆形成的帷幕，防渗材质均匀、型式单一，避免了土体防渗与岩体防渗的搭接，提高了防渗效果。
