Construction method of foundation pit slope pre-stressed anchor cable
The invention relates to a construction method of a foundation pit slope pre-stressed anchor cable, which belongs to the technical field of building construction, and comprises the following steps: S1, drilling: positioning a geological drilling machine on a first row of anchor cable operating platform by using a crane, adjusting and measuring the drilling position and the inclination angle of the drilling machine, fixing the drilling machine on the operating platform and a rock surface by using a fastener, and constructing from bottom to top, an upper layer of operation platform is erected in time along with the drilling progress; s2, anchor cable installation is conducted, specifically, a plurality of reinforced anchor cable structures are installed on the slope structure at equal intervals, a baffle is erected near each reinforced anchor cable structure, and the reinforced anchor cable structures are protected; hole bottom grouting construction is adopted for anchor cable grouting, mortar is injected from the hole bottom, air is exhausted from an exhaust hole, and a mortar position indicator is adopted for controlling the grouting position; and S4, anchor cable tensioning is conducted, specifically, anchor cable tensioning is conducted after grouting and anchor beam concrete reach 70% of the design strength, tensioning equipment is calibrated before anchor cable tensioning, and stress errors are avoided. The effect of improving the structural stability of the anchor cable is achieved.
本申请涉及一种基坑边坡预应力锚索的施工方法，属于建筑施工的技术领域，其包括以下步骤：S1、钻孔：利用吊车将地质钻机就位于第一排锚索操作平台，调整测量钻孔位置及钻机倾角，利用紧固件固定于操作平台及岩面上，自下而上施工，随钻孔的进度，及时架立上一层操作平台；S2、安装锚索：将多个加强型锚索结构等间距安装在边坡结构上，每个加强型锚索结构附近搭设挡板，对加强型锚索结构进行保护；S3、注浆：锚索注浆采用孔底注浆施工，砂浆由孔底注入，空气由排气孔排出，采用砂浆位置指示器控制注浆位置；S4、锚索的张拉：锚索张拉在注浆及锚梁砼达到设计强度70%后进行，张拉锚索前对张拉设备进标定，避免出现应力误差。本申请具有提高锚索结构稳定的效果。
