The Digital Twin Analyzes The Status of The Entire Life Cycle and Provides Technical Support for Decision-Making Such As Operation and Maintenance and Emergency Evacuation

The comprehensive pipe gallery has a large height difference, and there are a large number of 10Kv high-voltage power grids and communication pipelines around it. There are many problems such as water pipe cracking, uneven settlement, and horizontal displacement. The Yunlu Digital Twin Platform is used to monitor the structural health of the concrete pipe gallery and auxiliary pipelines to ensure their safe and stable operation. Through real-time parameter monitoring, the internal environment of the pipe gallery and the long-term changes of the water pipeline can be grasped in more detail, to provide timely and effective feedback on the safety status of the pipe gallery.

National Conference Center Phase II Steel Truss Unloading Monitoring Project

The unloading of the truss conversion structure with a total bearing capacity of 46,500 tons in the second phase of the National Convention Center is currently the largest steel truss conversion structure in China. "Crutch" support, to achieve "autonomous standing".

To ensure the structural safety of the steel structure during the unloading process, Yunlu Technology provided a real-time monitoring platform for the entire process of the unloading of the structure and continued to provide high-quality real-time monitoring services during the entire unloading process. When monitoring points and data permit, second-level structural analysis based on monitoring real-time data can be realized. Therefore, the changes in monitoring data can be analyzed in real-time to obtain changes in the internal forces and displacements of the entire structure, and help the project headquarters understand the redistribution of internal forces of the entire roof steel frame caused by the incomplete synchronization of the unloading points during the specific construction process. Find out whether there are abnormally changed components and their locations, and judge whether it is safe or not.

Beijing New Airport "Three Lines and Four Bridges" Construction Swivel Project

At 2 a.m. on December 2, 2018, the "Three Lines and Four Bridges" project, the main throat of Beijing Daxing International Airport Expressway, completed the highly difficult turning movement across the Beijing-Shanghai Railway after 90 minutes of continuous operation at night. The lines are accurately connected. Major news network media such as CCTV and China News Network paid attention to and reported this successful rotation.

As the real-time monitoring party for the rotating construction, Yunlu Technology has overcome several technical problems. Within the sub-millimeter accuracy range, it has ensured the safety and progress of the construction through engineering intelligence, and successfully assisted the rotating construction.
