Construction method for treating steep slope of karst area through grouting
The invention discloses a construction method for treating a steep inclined slope in a karst area through grouting, and belongs to the field of karst area construction methods. S2, drilling is conducted; s3, a grouting pipe is installed; s4, preparing slurry; s5, performing grouting operation; and S6, hole sealing. According to the geological characteristics of a karst development area, the position of the engineering pile located on the abrupt slope surface is determined by combining a one-pile-one-exploration and karst survey report, then grouting holes are buried in the periphery of the engineering pile, the karst area is reinforced through grouting, the hidden karst cave abrupt slope surface is eliminated, the stability and perpendicularity of drilling holes are ensured, and the stability and perpendicularity of the drilling holes are improved. And the possibility of inclined drilling and drill rod breakage caused by uneven stress of the drill bit is reduced.
本申请公开了一种注浆处理岩溶区陡倾斜坡施工方法，属于岩溶区施工方法领域，其包括以下步骤：S1、预处理区放样；S2、钻孔；S3、安设注浆管；S4、浆液制备；S5、注浆作业；S6、封孔。本申请根据岩溶发育区的地质特点，并结合一桩一探和岩溶调查报告，确定位于陡坡面的工程桩位置，然后在工程桩周边埋设注浆孔，通过注浆加固岩溶区，消除隐伏溶洞陡坡面，确保钻孔的稳定性和垂直度，减小由于钻头不均匀受力而导致斜钻、钻杆断裂的可能性。
