摘要
Abstract
The non-destructive testing technology of bolt is to use the principle of acoustic reflection to detect the grouting fullness and buried length of the grouting anchor,which has been widely used in various support projects.However,when the exposed length of the bolt is too long,the detection error obtained is larger,and the anchorage quality of the bolt can not be accurately reflected,the exposed length of the anchor rod of the rock wall crane beam of the underground powerhouse of the Yingliangbao Hydropower Project is more than 1 m,the number of bolts is large,and the requirements for the drilling grouting results are high.How to accu-rately and quickly implement the detection for research and analysis and discussion are expounded in this pa-per,and the results obtained can be used for reference for similar projects.关键词
