| Abstract: | Prestressed tunnel grouting quality of concrete beams is directly related to the safe use of the bridge,but there is no accurate method to determine the fullness of prestressed grouting tunnel.In this paper,theoretical research and field testing laboratory are combined used to introduce ultrasonic pulse wave detected the fullness of prestressed tunnel.It has discussed the feasibility of ultrasonic detection in metal prestressed grouting quality and present the impact factor affect of the ultrasonic testing quality,which will provide scientific and reliable protection discussed for effective monitoring of prestressed concrete beam construction quality. |
