360° CALIBRATION
Sisgeo is proud to introduce an innovative inclinometer based on a 3-axis Micro Electro Mechanical (MEMS) accelerometer.The selected MEMS has optimal thermal and long-term stability characteristics itself. Sisgeo tested it carefully to guarantee the final performances. However, the accelerometer itself is not capable to provide accelerations with enough accuracy and linearity to make inclination measurement, […]
BRAIN tutorial
This video shows how simple and intuitive is to use the new BRAIN inclinometer system. The system, composed by the BRAIN APP, bluetooth cable reel and MEMS inclinometer probe, is completed with the accessories (dummy/test probe and pulley cable stop). The technician in the video simply described the basic operations for an inclinometer survey. Detailed […]
Rome Metro C project – Historical heritages monitoring
Along its route, Line C interacts with historical heritages that are unique in the world and protected by UNESCO. Thousands of Sisgeo instruments are installed along Metro C line to protect civil structures, buildings and monuments. With this video, Sisgeo would like to focus the attention to the monitoring of Rome most famous historical buildings: […]
Tunnel monitoring – chapter 5 – Buildings above tunnel excavation
In this set of video (Tunnel monitoring) we would like to present some monitoring solutions that could be used during tunnel excavation. The chapter 5 is dedicated to the monitoring solutions for the buildings above excavation zone and will close the set of video with simple description of data acquisition systems and WMS web monitoring […]
Tunnel monitoring – chapter 4 – Underground stations
In this set of video (Tunnel monitoring) we would like to present some monitoring solutions that could be used during tunnel excavation. The chapter 4 is dedicated to the underground stations monitoring, usually excavated with the cut and cover method. The instruments proposed are vibrating wire strain gauges and load cells to monitor stress and […]
Tunnel monitoring – chapter 3 – Ground above tunnel excavation
In this set of video (Tunnel monitoring) we would like to present some monitoring solutions that could be used during tunnel excavation. The chapter 3 presents some possible solutions to monitor displacements, settlements and pressures in the zone around the excavation for tunnels with small coverage, typical in metro tunnel excavation. Main applied instruments are […]
Tunnel monitoring – chapter 2 – TBM concrete lining
In this set of video (Tunnel monitoring) we would like to present some monitoring solution and suggestion that could be used during tunnel excavation. The chapter 2 is dedicated to TBM excavation method and concrete line monitoring solution. Main applied instruments are vibrating wire strain gauges embedded into the concrete lining to monitor the stress […]
Tunnel monitoring – chapter 1 – Philosofy, entrance, cross sections and excavation face
In this set of video (Tunnel monitoring) we would like to present some monitoring solutions that could be used during tunnel excavation. The chapter 5 is dedicated to the monitoring solutions for the buildings above excavation zone and will close the set of video with simple description of data acquisition systems and WMS web monitoring […]
What is a piezometer, how it works, available technologies and models
With this presentation, we would like to introduce the meaning of « piezometers », their classification (open and close circuit piezometer), method of reading (deep meter or electrical piezometers), available technologies (piezo resistive or vibrating wire sensor) and the main models available. Electrical piezometers include common vibrating wire piezometers, heavy duty piezometers, multipoint piezometers, removable transducers for […]
Mining monitoring instrumentation
Mine monitoring system shall be designed starting from the mine-typology: open pit mine or underground mine (cavern). In open pit mine is really important to monitor the stability of rock/soil walls with inclinometers, incremental extensometers, piezometers and wire extensometers. In underground mining become critical to monitor the stress and displacements of the excavated rock and […]
Landslide monitoring instrumentation
Landslides are monitored following different parameters like landslide type, layers type, displacement speed, etc… The most utilized geotechnical instruments for this purpose are the inclinometer casings (or inclinometer tubes) able to control horizontal movement into the ground. Inclinometer casing can be read with portable inclinometer system or with IPI / BH Profile probes (automatic Inclinometer […]
Dam safety and monitoring
Planning a performance monitoring program is an essential component of successful dam construction and operation. Dam monitoring is recommended to ensure the safety of a dam. Geotechnical instrumentation and structural instruments are used to determine the initial conditions at dam site, monitoring during construction, initial filling and drawdown; and assist long-term monitoring. One of the […]
