Borehole extensometer
Solexperts uses different extensometers depending on the requirements:
- For standard applications Solexperts - Modular Extensometer
- M-RHX (Modular-Reverse-Head-Extensometer) for recording the displacements in the tunnel face during the excavation
- Fixed-installation micrometer (FIM) for continuous recording of borehole-axial deformations
Installation
Installation of extensometers is carried out by experienced Solexperts personnel. This includes:
- Coordination with on-site boreholes and injections
- Assembling the extensometer with injection and venting hoses, if necessary with an injection packer or geotextile socks and borehole brackets for overhead installation.
- Installation of the extensometers in a professional way
- Supervision and control of the injection carried out on site
- Installation of the displacement transducers and data loggers
- Zero measurement and start-up of the measuring system with automatic data acquisition and remote data transmission
