Rsm-Prt (M) Low Strain Integrity Testing Pile Integrity Tester Foundation Pile Driving Detector

The RSM-PRT (M) performsTwo Channels Low Strain Integrity Testing, which is a widely used measurement method to check the integrity of concrete foundation piles. It is available with two channels of date acquisition. Accessed a top mount accelerometer, it obtains conventionally measurement of single velocity. With two side mount accelerometers, it can read measurement of dual velocity.Principle
The test is based on wave propagationtheory. The name "low strain pile integritytest" stems from the fact that when a light impact is applied to a pile it produces a low strain.
The impact generates a stress wave that travels down the pile. When the downward stress wave encounters a change in cross section or in concrete quality, it generates reflected wave that is later observed at the pile top. By analyzing the propagation time, amplitude and phase of that reflected wave, it has evaluation of pile integrity ultimately.The LSPIT-Testing isconducted in accordance to:
