Construction safety monitoring in underground parking
Sensors are regularly used in civil and construction industry engineering to monitor safety during and after construction. Our sensors can be used during the various building phases of an underground parking garage.
- Construction pit monitoring
- Permanent construction
- Predictive maintenance
Construction pit monitoring
A construction pit is a temporary construction during the digging phase of an underground parking. The installation of sturdy sheet pile walls must prevent subsidence. Vibration sensors are very suitable for monitoring the ambient vibrations, for example when piling the foundation. Especially important when digging in urban areas. But also the construction pit itself can also be subject to monitoring, for example by using geotechnical inclinometers to determine the (undesired) slope of a sheet pile wall.
After the placement of the construction pit and the excavation of it, the permanent construction will be installed. Conventional sensors such as potentiometers, pressure sensors and linear position sensors with analog output can be used to ensure that the definitive construction is built according to the regulations. It is also possible to use fiber optic sensors, these sensors have the advantage that they guarantee years of accurate data without intermediate calibrations.
After the construction, vibration sensors are often used to monitor whether the structure remains within specifications. This information is important for determining predictive maintenance. Fiber optical cables are extremely suitable for this, because multiple types of sensors can be connected. This makes it possible to connect the cables to vibration and force sensors during construction and to these with linear sensors and pressure sensors after construction.
