Anti-floating anchor rod construction method in karst rock area
The invention discloses a construction method for an anti-floating anchor rod in a karst rock area. The construction method for the anti-floating anchor rod in the karst rock area comprises the following steps that S1, an anchor hole is formed through drilling of a drilling machine according to the preset depth; S2, a built-in steel sleeve with the closed bottom end is placed in the anchor hole, so that the built-in steel sleeve and the anchor hole are coaxially arranged, and a gap is reserved between the outer wall of the built-in steel sleeve and the inner wall of the anchor hole; S3, cement paste is poured between the outer wall of the built-in steel sleeve and the inner wall of the anchor hole, and an air bag layer is inflated to prevent the cement paste from flowing into a karst cave before the cement paste is poured; S4, an anchor rod is manufactured and inserted into the built-in steel sleeve, so that the anchor rod and the built-in steel sleeve are coaxial; and S5, the cement paste is poured into the built-in steel sleeve. When the anchor hole penetrates through the karst cave, the situation that the cement paste flows into the karst cave is prevented, and the normal construction effect of the grouting procedure is guaranteed.
本申请公开了一种溶岩地区的抗浮锚杆施工方法，其包括以下步骤：S1、通过钻机按照预设深度钻进形成锚孔；S2、于锚孔中放置底端封闭的内置钢套管，使内置钢套管与锚孔同轴设置，且内置钢套管的外壁与锚孔的内壁之间留有间隙；S3、向内置钢套管的外壁和锚孔的内壁之间灌注水泥浆，灌注水泥浆前，先对气囊层进行充气防止水泥浆流入于溶洞中；S4、制作锚杆并将锚杆插入于内置钢套管中，使锚杆与内置钢套管同轴；S5、向内置钢套管中灌注水泥浆。本申请具有当锚孔穿越溶洞时，防止水泥浆流入于溶洞中，保证了注浆工序的正常施工的效果。
