Experimental Research on Detection of Duct Grouting Quality of Prestressed Corrugated Pipe with Ultrasonic

WANG Feng;ZHANG Feng;Shaanxi Transportation Construction Group Co.Ltd.;Research Center for Geotechnical and Structure Engineering,Shandong University;  
Aimed at the problems that happen when detecting the quality of duct grouting of prestressed corrugated pipe with ultrasonic,defects were set in the pipes on purpose,and detection was conducted with ultrasonic when the corrugated pipe was empty,1/4stuffed,half stuffed,3/4stuffed and fully stuffed and was buried in the concrete slab.The results show that with ultrasonic detection the quality of duct grouting can be effectively evaluated.
