Construction method of anchor cable hole
The invention discloses a construction method of an anchor cable hole, the included angle between the axial direction of the anchor cable hole and the horizontal plane is an acute angle, the construction method comprises the following steps: adjusting a drilling machine, positioning according to a design position and drilling for a preset distance, and performing rock coring and hole forming; after the core sample is taken out, a coring track is measured, and coring deviation is obtained; the drilling direction is adjusted according to the coring deviation; continuously drilling, and measuring whether drilling deviation occurs or not after coring and hole forming of the hole entering section are completed; when drilling deviation occurs, an adjusting mechanism is put down, and the drilling direction is corrected; the procedures of drilling, slag removing, measuring and deviation rectifying are circularly conducted till drilling construction is completed; cleaning the hole, mounting the anchor cable steel strand after the anchor cable steel strand is qualified, and then tensioning, pouring concrete and curing the anchor cable steel strand. According to the construction method of the anchor cable hole, the construction precision can be controlled, and the deviation of the anchor cable hole is controlled to be within the design range.
本申请公开一种锚索孔的施工方法，所述锚索孔的轴向与水平面的夹角为锐角，所述施工方法包括以下步骤：调整钻机，按设计位置定位并钻进预定距离，进行岩石取芯成孔；取出芯样后，测量取芯轨迹，得到取芯偏差；根据取芯偏差调整钻进方向；持续钻进，完成入孔段取芯成孔后，测量是否发生钻进偏差；发生钻进偏差时，下入调整机构，对钻进方向进行纠偏；循环进行钻进、清渣、测量、纠偏的工序，直至完成钻孔施工；清孔，复测验收合格后安装锚索钢绞线，之后张拉、浇筑混凝土，养护。本说明书所提供的锚索孔的施工方法，能够控制施工精度，控制锚索孔的偏差在设计范围内。
