The GEOSmart In-Place Inclinometer

GEOSmart is an in-place inclinometer consisting of closely spaced MEMS (Micro-Electro-Mechanical Sensors) approximately 0.6m apart that are mounted on stainless steel tubing with a single cable running the length of the string which reduces the number of cables protruding from the top of the borehole. It is comprised of a biaxial probe, cable reel, and an ultra-rugged Field Tablet supplied with ‘In-Port Pro’ data capture software.

GEOSmart is installed in either Schedule 40 or 70mm casing and is used to monitor displacement in geotechnical applications including;

  • Diaphragm walls
  • Embankments
  • Retaining walls
  • Landslides
  • Potential slope failures.

Due to its lightweight robust construction with joints capable of bending up to 90º, the GEOSmart system is conveniently transported to the site and can be installed by one site technician.

GEOSmart In-place Inclinometer Operation

The GEOSmart system contains several sensor nodes in a vertical string installed in either Schedule 40 PVC or in a 70mm inclinometer casing. The pipe or casing provides access for subsurface measurements. The joints between each sensor are robust, allowing the system to maintain a consistent orientation of all the nodes, regardless of whether it is installed in PVC pipe or ABS inclinometer casing.

The pipe or casing is typically installed in a vertical borehole that passes through a suspected zone of movement. The nodes are spaced 0.6 metres apart and provide a reading resolution similar to a traversing probe. The system spans the zone of movement and when the ground moves, the pipe/casing moves with it, changing the inclination of the nodes inside.

Inclination measurements from the nodes are processed to provide graphs of the casing profile and changes in the profile. A change in profile may indicate displacement or movement. The GEOSmart system is connected to a data acquisition system, and readings are transmitted to processing software triggering alarms based on displacements or rate of change.
