The sounding tube is composed of a bottom pipe, a middle pipe, a bottom plug and a sealing rubber ring. The main material of the sounding tube is the thin wall welded pipe, and the material is generally Q195 - Q235 -Q235B. The specifications of commonly used thin-walled welded pipes for acoustic tubes are mainly the following Special thin-walled welded pipe for acoustic tube
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
