non-destructive testing >pile and borehole inclination testing
Use in wells:
Once the required borehole depth is reached, the inclinometer is rigidly attached to the drill bit (bucket or auger) and the depth encoder hung from the rig. The drilling point is then lowered (with minimal turning) into the hole. During descent, at predetermined depths, the management software requests a stop for the amount of time necessary for inclination reading. The deviation is calculated in real time by integrating the inclination over depth. The procedure must be repeated also when pulling the bucket upwards to the surface to distribute the resulting error over the whole depth.
Use on existing piles:
The BIT sensor with relative centering device is lowered into the standard access tube. Manual descent is controlled by the software by means of the encoder and is stopped every so often to make measurements. The procedure must be repeated also when pulling the bucket upwards to the surface to distribute the resulting error over the whole depth.
