Case Study: Monitoring of Existing Bridges and Temporary Bridges During Construction Work
In a challenging infrastructure project, monitoring of an existing bridge and adjacent temporary bridges was required to ensure safety during extensive construction work. The project involved drilling and pile-driving operations as well as the renewal of an underlying railway embankment. The deployed technologies and monitoring concept provided precise real-time data to ensure structural stability throughout the construction process.
Monitoring of the Existing Bridge
To monitor the existing bridge, state-of-the-art tilt sensors with integrated laser distance measurement were deployed. These sensors were installed on the bridge abutment and operated on battery power to ensure maximum flexibility. The monitoring covered both non-uniform and uniform settlements:
- Non-uniform settlements: Detected by the tilt sensors, which measured even the smallest changes in the structural stability of the bridge.
- Uniform settlements: Monitored using the integrated distance lasers, which precisely tracked vertical movements.
The sensor data was transmitted in real-time via a gateway installed near the structure. This enabled continuous monitoring of the bridge throughout the construction process and provided engineers with valuable insights for assessing structural safety.
Monitoring of Temporary Bridges in Compliance with DB Guideline 804.4111
During the renewal of the embankment, temporary bridges were installed in front of and behind the existing bridge. These were continuously monitored in compliance with railway guideline 804.4111. Distance lasers were deployed, mounted at fixed static positions, to monitor even the smallest shifts or settlements using target plates attached to the temporary bridges.
- Precise Measurements: The distance lasers performed multiple measurements per second, enabling the detection of even minute changes in real time.
- Long-Term Monitoring: Continuous data acquisition ensured permanent monitoring, safeguarding the stability of the temporary bridges throughout the construction process.
Result
By utilizing tilt sensors with laser distance measurements and ensuring continuous monitoring of the temporary bridges, the project was successfully and safely executed. Seamless real-time data acquisition enabled rapid decision-making in response to structural changes, effectively minimizing potential risks.
This case study clearly demonstrates how Infrasolute’s innovative monitoring technologies contribute to the safe and efficient execution of even the most complex construction projects.
- The sensors detected even the smallest angular changes in the railway sleepers.
- Using an integrated data platform, elevations, torsions, and deformations were calculated based on the tilt data.
- If predefined thresholds were exceeded, automatic and proactive alerts were triggered.
Case Study: Monitoring of Railway Sleepers
As part of a complex infrastructure project, temporary bridges were installed to maintain traffic flow during construction work.
In compliance with DB Guideline 804.4111, continuous monitoring of the railway sleepers in the backfill area of these bridges was required to ensure their deformation control and structural stability.
Deployed Technology: Tilt Monitoring with Integrated Distance Lasers
Innovative tilt sensors with integrated distance lasers were used for monitoring. These sensors enabled multidimensional monitoring of the railway sleepers:
Tilt Sensor Technology:
- The sensors detected even the smallest angular changes in the railway sleepers.
- Using an integrated data platform, elevations, torsions, and deformations were calculated based on the tilt data.
- If predefined thresholds were exceeded, automatic and proactive alerts were triggered.
Laser-Distance Measurement:
- The integrated distance laser monitored the horizontal movements of the railway sleepers.
- To ensure precise reference measurements against fixed static points, stakes with target plates were anchored into the ground next to the railway track, creating an accurate reference.
Real-Time Monitoring and Alerting
The sensors were directly connected to a digital data platform, which analyzed and stored real-time data. This platform enabled continuous monitoring and immediate response to threshold exceedances, ensuring the safety of the railway sleepers and temporary bridge structures.
Proactive Maintenance and Risk Minimization
By combining high-precision measurements with automated alerts, proactive maintenance was enabled. Risks were detected and mitigated early, preventing critical damage before it could occur.
Result
The use of tilt sensors with integrated distance measurement ensured that the railway sleepers met the high standards of DB Guideline 804.4111. The seamless monitoring not only guaranteed the safety of the temporary bridges but also provided a foundation for efficient maintenance measures and long-term operational reliability.
This project demonstrates how Infrasolute’s advanced monitoring technologies contribute to the safe and compliant execution of complex construction projects.
