GEOSmart In-Place Inclinometer Overview

Geomotion are pleased to present the new GEOSmart in-place inclinometer to complement our comprehensive range of geotechnical instrumentation.

GEOSmart consists of MEMS (Micro-Electro-Mechanical Sensors) spaced 0.5m apart achieving the highest resolution of borehole inclination data on the market.

​The sensor is mounted on a stainless steel tube with a single cable running the length of the string which is connected to a datalogger at the top of the borehole.

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

Product Features
  • Real Time Monitoring
  • Sensors are connected sequentially
  • Borehole displacement in engineering units (mm/m)
  • Nodes pre-loaded with calibration information
  • Modular and robust design
  • Lightweight with joints capable of bending 90°

Product Benefits
  • GEOSmart is ideal for continuous, unattended monitoring and can deliver readings in real time.
  • Only one signal cable per borehole, quicker installation and simplified connection to the data logger.
  • Less post processing in the monitoring software resulting in the reduction of possible calculation errors.
  • Quicker and easier installation as segments can be installed in any order.
  • GEOSmart can be removed at the end of the project and redeployed on new applications.
  • Compact and convenient shipping in a box approximately 60 x 60 x 32cm that can be installed on site by one person.

Operation
The system contains a number of sensor nodes in a vertical string installed in either Schedule 40 PVC or in 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 0.5 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. Changes indicate displacement (movement). The GEOSmart system is connected to a data acquisition system, and readings are
transmitted to processing software that can trigger alarms based on displacements or rate of change.
