Foundation pit inrush karst cave path approaching searching drilling positioning method
The invention belongs to the technical field of civil engineering and traffic engineering, and particularly relates to a foundation pit inrush karst cave path approaching searching drilling positioning method. The method comprises the following steps that S01, a drilling arrangement plane grid chart is drawn, specifically, detailed exploration karst cave drill holes, detailed exploration non-karst cave drill holes and the positions of inrush points are marked differently; s02, locally densifying a drilling grid: taking the midpoint of the detailed exploration karst cave drilling hole and the adjacent detailed exploration non-karst cave drilling hole as the center, and enabling a locally densifying drilling line to be parallel to the original drilling grid; meanwhile, by taking the inrush point as the center, locally densifying the drilling grid parallel to the original drilling grid; s03, searching the karst cave around the detailed exploration karst cave drill hole and the gushing point in an approaching manner; s04, determining a karst cave boundary line; s05, determining a karst cave path trend line; s06, determining the range of the karst cave outside the waterproof curtain of the foundation pit; s07, determining karst cave distribution in the depth direction; and S08, the karst cave channel is cut off outside the waterproof curtain of the foundation pit for water plugging. Compared with the prior art, the method can shorten the water plugging rescue time and save the grouting material for plugging the karst cave.
本发明属于土木与交通工程技术领域，具体为一种基坑突涌溶洞路径逼近搜索钻探定位方法。其包括如下步骤：S01、绘制钻探布置平面网格图：区别标注详勘溶洞钻孔、详勘非溶洞钻孔与突涌点位置；S02、局部加密钻探网格：以所述详勘溶洞钻孔与相邻所述详勘非溶洞钻孔的中点为中心，与原钻探网格平行局部加密钻探线；同时，以突涌点为中心，与原钻探网格平行局部加密钻探网格；S03、在详勘溶洞钻孔和突涌点四周逼近搜索溶洞；S04、确定溶洞边界线；S05、确定溶洞路径走向线；S06、确定基坑止水帷幕外溶洞范围；S07、确定深度方向溶洞分布；S08、在基坑止水帷幕外截断溶洞通道堵水。与现有技术相比，该方法可缩短堵水抢险时间，节省封堵溶洞注浆材料。
