GEOTECHNICAL MONITORING

An inclinometer is used to monitor horizontal or vertical displacements in soil or structures. It’s used to detect movements in slopes, embankments, walls, retaining structures, or construction pits.

An inclinometer casing tube is installed in a borehole or an embedded structure; in the case of a horizontal inclinometer, it’s placed beneath an embankment. Inside the casing tube, an inclinometer probe (with two precise tilt sensors) measures the inclination of the casing tube at various depths. By taking successive measurements over time, the displacement of the soil or structure can be calculated.

SLP performs inclination measurements with a SISGEO measuring instrument (inclinometer probe), using the B.R.A.IN. system.

For performing measurements and recording data, the B.R.A.IN. APP is used. This application is installed on a smartphone, which communicates with the probe via a Bluetooth connection.

A tiltmeter measures changes in the tilt or rotation of a structure or geotechnical structure. It’s used to monitor movements in embankments, slopes, construction pits, foundations, bridge piers, and buildings.

Tiltmeters detect small changes in inclination (in degrees or milliradians), allowing for early detection of movement and potentially dangerous changes in the structure’s stability.

SLP uses Worldsensing’s LS–G6–TIL90–X digital tiltmeters with remote data acquisition, which enables tilt detection across all axes (3D).

For data recording and access, the LS–G6–GW wireless base station (Gateway – Wi-Fi/GSM Antenna) is used. This provides connectivity to the tiltmeters via the Worldsensing CMT Edge application, accessible online or through a smartphone app.
