| Abstract: | How to detect the defects of manual digging piles accurately and rapidly is one of important engineering problems. The essay introduces the radical theory of detecting pile integrity by ultrasonic transmission method and analyses the relations between the parameters of acoustics and the quality of concrete. With the comparison between the testing results and defective designs of two model piles,ultrasonic transmission method can detect the position,size and destroyed degree of manual digging piles,which dem... |
