Pile integrity test

The pile integrity test ( PIT) is a method for materials testing.

In practice, all drilled concrete are tested in a construction site on integrity. Before the pile is tested, the concrete must have completely set. Are pried at least the first 10 cm of the pile head, in order to ensure a homogeneous quality of the concrete. The pile integrity test ( PIT Sheet Pile Integrity Test) is a post - test method in which with the help of the sound wave speed, the duration of the pile head is measured to pile base. The stake auditor fails with a hammer on the previously prepared Bohrpfahlkopf and triggers a sound pulse. The sound wave propagates through the Bohrpfahllänge and is reflected at the base. A sensor measures the pulses at the pile head and transmits the signals to a computer on. Consequently, calculated from this measurement, the pile length. If the level is " disturbed " pile with constrictions of the sound wave pulse is reflected earlier. The recorded sound waveform can now be interpreted by Bohrpfahlprüfer.
