The sound measuring pipe can be directly fixed on the inside of the reinforcement cage: the fixing method can be welded or tied, and the pipes should be kept basically parallel to each other -- if the test results need to evaluate the strength of concrete at each measuring point, the non-parallelism should be controlled below 1‰.Reinforcement cage should be placed into the pile hole to prevent distortion.[1]

The pipe is generally installed in sections along with the steel cage, and the joint between each section can adopt the anti-thread socket joint or the sleeve welding scheme, as shown in FIG. 8: if the bellows are adopted, the bellows of a larger size can be used for the joint, and the two ends of the sleeve pipe can be wrapped and sealed with adhesive tape.Both the joint scheme must ensure that under high hydrostatic pressure not leak slurry, interface wall should be kept flat, there should be no welding slag, burr and other projections, shift of the freely so as not to interfere with the probe, the sound should be sealed on the bottom of the tube, after the installation should be easy to use cork plug, to avoid falling into a foreign body, when pouring concrete channel congestion.
