Structural Monitoring on the Quinto Centenario Bridge

Customer: IT TRIGGERS.

Project: Monitoring of the Pilonos of the Quinto Centenario Bridge at a height of 110 meters.

Project Description:

EASTAV GLOBAL was contracted by ACCIONA to monitor the pylons of the Quinto Centenario Bridge. This project aimed to guarantee the stability and safety of this important structure through the accurate and efficient installation of monitoring prisms.

Challenges

• Complicated Access: The bridge's pillars are difficult and dangerous to access due to their height and design.
• Weather Conditions: Working at high altitude exposes technicians to adverse weather conditions that can change rapidly.
• Need for Speed and Accuracy: The installation of prisms should be quick to minimize exposure time to risks and accurate to ensure the accuracy of the monitoring data.

Implemented Solutions.

• Access via Artificial Climbing:
  • Technique Used: Artificial climbing was used with the placement of removable Pulse anchors, allowing safe and controlled access to the pylons.
  • Anchor Specification: Pulse removable anchors were selected for their reliability and ease of installation and removal, minimizing impact on the bridge structure.

• Rope Rope Installation:
  • From the Upper Area: Rope lines were installed from the top of the pylons, facilitating access to all their faces.
  • Prism location: The prisms were strategically placed a few centimeters from the edge of the pylons to maximize monitoring accuracy.

• Installation with Impact Gun:
  • Speed and Efficiency: The use of an impact gun allowed a quick and safe placement of the anchors that fix the prisms to the structure.

• Additional Security Measures:
  • Temporary Horizontal Lifelines: To increase the safety of technicians, temporary horizontal lifelines were installed.
  • Battery descender: Battery descenders were used, making it easier for technicians to climb safely, quickly and comfortably.

Conclusion

The success of this project reinforces EASTAV GLOBAL's commitment to excellence and safety in all its work. Our ability to adapt to challenging conditions and use advanced technologies positions us as leaders in the field of structural monitoring.
