Pore pressure measurements are used in securing piling sites and terraces. Measurements are also used to support foundation planning and for monitoring earth-fill dams, for example. The rapid increase of pore pressure, for example, at a piling site can cause a collapse of ground load-bearing capacity, which can lead to a serious accident.
Measuring device
The typical measuring range of pore pressure sensors is 0-5 bars Several pore pressure heads can be connected to a measuring point at various levels. Pore pressure sensors, that is, piezometers, are inserted into the ground by using threaded steel tubes that are attached to the sensors. The central processing unit of this device transfers the measurement data automatically to FinMeas Online, that provides you with an easy access to up-to-date measurement data from any device.
Benefits
- Real time and exact information of the possible changes in pore pressure
- Measuring sensors detect inside the structure that what cannot be seen from the outside
- The system raises an alarm immediately if the pore water pressure exceeds a permissible value
- Measurements can be used to support foundation planning
- Remote reading reduces unnecessary costs, delays and risk of errors
