The sonic tube is the channel for the probe to enter the pile body when the pile is used for ultrasonic testing. It is an important part of the ultrasonic testing system for cast-in-place pile. The pre embedding method in the pile and the layout of the pile on the cross section of the pile will directly affect the test results. Therefore, the burying arrangement of acoustic tube is particularly important, we must strictly control the burying quality, in order to ensure the smooth completion of the project.
The application of the clamp pressure sonic tube is as follows
