Research on the Technology of Defects Detection in Prestressed Pipe Grouting

Nondestructive testing technology on prestressed pipe grouting is an important issue in recent years. Some research methods including Radar Method, Ray Method, and Impact Echo Method were contrasted and verified in this paper. The applicable scope and the defect detectable effect of these methods mentioned above was studied exploringly. The achievements obtained this paper were certain to be significant for the detection on pipeling grouting quality and defect inside concrete.
