Construction method of soil slope expanding anchoring body anchor cable reinforcing structure
The invention relates to a construction method of a soil slope expanding anchoring body anchor cable reinforcing structure in order to give full play to the advantages of the anchor cable structure inreinforcing a high slope. The construction method comprises the following steps that (1) positioning marking is carried out, and drilling is carried out to form an anchor cable drilling hole; (2) a prefabricated annular shell is installed on an expanding reinforcing device to form a temporary combination body; (3) the temporary combination body is put into the first subsection of the inner end ofthe anchor cable drilling hole in an anchor cable anchoring section; (4) a pressure chamber of the expanding reinforcing device is pressurized to enlarge the aperture; (5) the pressure is released, and the expanding reinforcing device is taken out; (6) another temporary combination body is put in the next subsection of the anchor cable drilling hole in the anchor cable anchoring section, the steps (4) and (5) are repeated to form reaming of the subsection of the anchor cable drilling hole and implantation of the prefabricated annular shell; (7) the step (6) is repeated to form reaming of allthe subsections of the anchor cables drilling hole and implantation of the prefabricated annular shells; (8) an anchor cable steel strand and a free section casing pipe are put in, and high-pressure grouting is carried out to form an anchor body; (9) and an anchor cable reinforcing frame is constructed on the surface of the side slope, and an anchor cable is tensioned and fixed.
一种土质边坡扩大锚固体锚索加固结构的施工方法，以充分发挥锚索结构在加固高边坡中优势。包括如下步骤：①进行定位标记，钻孔形成锚索钻孔；②把一组预制环形壳体安装在扩大加固装置上形成临时组合体；③向锚索锚固段内锚索钻孔里端的第一分段位置放入临时组合体；④对扩大加固装置的压力舱加压使其孔径扩大；⑤卸压取出扩大加固装置；⑥再次在锚索锚固段内锚索钻孔的下一分段位置放入临时组合体，重复步骤④和步骤⑤，形成对该分段锚索钻孔的扩孔和预制环形壳体的植入；⑦重复步骤⑥，形成对所有分段锚索钻孔的扩孔和预制环形壳体的植入；⑧放入锚索钢绞线和自由段套管高压注浆形成锚固体；⑨在边坡坡面施工锚索加固框架，张拉和锁定锚索。
