自由式单孔多锚头防腐型预应力锚索的施工质量控制

Construction Quality Control of Free Style Single Hole Multi Anchor Head Anticorrosive Pre-stressed Cable

锦屏一级水电站存在复杂的不良地质现象,设计采用了大量的自由式单孔多锚头预应力锚索,对各级边坡进行加强支护处理。针对锚索施工专业性强、施工工艺复杂、质量控制节点多的特点,从此类型锚索的施工工艺入手,全面介绍了各施工环节的质量控制要点。

There is complex and badly geologic condition in Jinping grade 1 bydropower station. Free style single hole multi anchor head pre-stressed cable was used in design to strength the support of different level slope. Based on the characteristics of strong specialty of construction, craftwork complex, and multi points of quality control, the key points of quality control during different construction phases was introduced from construction craftwork of this type of anchor and cable.
