As the main instrumentation Lurtek carries out the supervision of the installations and control of the following geotechnical instrumentation:
Installation and measuring to detect horizontal movements in screens, walls, landslides, etc. Accumulated and incremental movements with reference to the two perpendicular axes.
Recording of settlements along a line under embankments, landfills, etc., in areas where settlements are likely to occur. Geometric monitoring of embankments.
Installation and measurement of vibrating wire piezometers to determine hydrostatic pressure in land with groundwater and piezometric levels. In open piezometers the measurement is carried out with a probe that detects fluid levels.
Installation and measurement of pressure cells to determine loads in embankments, tunnels, footings, walls, etc.
Installation and control of continuous measurement systems of loads on studs and anchors by means of hydraulic or vibrating wire methods.
ANCHOR TENSIONING TESTING:
Control and checking of active loads on studs and anchors.
MESUREMENT WITH VIBRATING WIRE INSTRUMENTS:
Measurements with instruments based on vibrating wire systems such as extensometers, crackmeters, thermometers, etc.
LOAD TESTS ON DRIVEN PILES:
Measurement of vertical and horizontal displacements in foundation systems based on metal driven piles, subjected to different specific loads.
Resistance tests on the extraction of metal driven piles placed in different types of terrain or with different driving methods.
