小湾水电站堆积体边坡支护与锚索技术应用
Reinforcing of deposit slopes of Xiaowan Hydropower Station and application of prestressed anchorage cables
摘要
Abstract
With regard to the deposit slopes of Xiaowan Hydropower Station, the relevant reinforcing measures were analyzed, and the application of prestressed anchorage cables was highlighted. The results indicate that the slope reinforcements in the study area comprehensively adopt engineering protection and ecological protection techniques. The pre-stressing anchorage cables are the principal part of the engineering, and their drilling and grouting are the difficulty and keystone of the anchorage technology. The technology of concentric drilling and eccentric drilling with pipes can availably solve boring problem. By wrapping geotextile and thin canvas outside the prestressed steel strand, it can make concrete calculi protect steel strand of tensile section and reduce grouting quantity so as to avoid grouting waste.关键词
