Novel small-dip-angle tension-compression dispersed anchor cable construction process
The invention discloses a novel small-dip-angle tension-compression dispersed anchor cable construction process, and belongs to the technical field of building construction. The construction process comprises the following steps of preparation before construction, site leveling, anchor cable hole position rechecking, drilling machine in-place, pipe-following drilling, anchor cable hole cleaning, steel strand bundle placing, grout stop valve installing, grouting, anchor pier construction, anchor cable tensioning and anchor sealing. A drill bit and a drill rod are withdrawn from a sleeve after the drilling depth is 5m or 10m, residues in the sleeve are cleaned by high-pressure air, a horizontal digital compass inclinometer is placed in the sleeve, and the inclination angle of the sleeve is measured, so that the inclination angle of an anchor cable hole is adjusted, and accurate positioning of an anchor cable is guaranteed.
一种新型小倾角拉压分散型锚索施工工艺，属于建筑施工技术领域。它包括如下步骤：施工前准备，平整场地、复核锚索孔位，钻机就位，跟管钻进，锚索孔清理，安放钢绞线束，安装止浆阀，注浆，施工锚墩，张拉锚索及封锚。通过进尺5m或10m后从套管中退出钻头、钻杆，用高压空气把套管内残渣清理干净，将水平数字罗盘测斜仪放入套管内，测量套管倾角，据此来调整锚索孔倾角，保证锚索精确定位。
