Anchor cable construction method for ultrahigh large slope gravel slope
The invention relates to an anchor cable construction method for an ultrahigh and large slope gravel slope, which comprises the following steps: counting the number of anchor cables and the length of the anchor cables of each grade of slope into a table, and bundling the finished anchor cables; arranging a crane machine after the anchor cable is processed and accepted to be qualified, hoisting the anchor cable to each stage of slope platform by constructors in sections, and customizing a protective sleeve at the tail part of the processed anchor cable; a pre-stressed anchor cable is manually installed after being accepted and accepted, a vertical steel pipe is arranged on each grade of slope top platform to serve as a safety rope hanging point, a drilling machine is used for drilling, a steel pipe of a construction outer frame is vertically placed in a hole, a small transverse rod is erected at an outer frame vertical rod and used for fixedly installing a fixed pulley, the anchor cable is installed through the pulley, and the installed anchor cable is subjected to first-time grouting; concrete grouting is adopted between the steel pipe and the hole wall to ensure firm fixation of the steel pipe; and the anchor cable holes are grouted for the second time, and the frame body is dismantled. The anchor cable construction method is rapid and safe, reduces manual work, is used for anchor cable construction of the ultrahigh large slope gravel slope, and greatly improves the construction efficiency.
本发明涉及一种超高大斜面碎石边坡的锚索施工方法，对各级坡锚索数量及锚索长度统计成表，且将成品锚索进行捆扎；锚索加工完成验收合格后安排吊车机械，施工人员将锚索分段吊至各级坡面平台，对加工好锚索尾部定制保护套；预应力锚索验收合格后采用人工安装，每级坡顶平台均设置竖向钢管作为安全绳寄挂点，钻机钻孔，将施工外架的钢管竖向放置于孔内，外架立杆处搭设一根小横杆，用于固定安装定滑轮，使用滑轮安装锚索，对安装完成锚索进行第一次注浆，钢管与孔壁之间采用混凝土灌浆，保证钢管固定牢靠；对锚索孔进行第二次注浆，并拆除架体。本发明快速安全且减少人工锚索施工方法，用于超高大斜面碎石边坡锚索施工，大大提高了施工效率。
