OVM Achieves Milestone with First Visualized Smart Monitoring Application for Continuous Pushing System

In recent days, under the power of OVM's hydraulic continuous pushing system, the Ma'anshan-side section of the Chaohu-Ma'anshan Railway Ma'anshan Yangtze River Road and Rail Bridge auxiliary channel, weighing an impressive 13,000 tons, was successfully positioned. This structure, known as the world's largest span for a ballastless track with a three-cable-plane steel truss girder inclined cable-stayed bridge, marks a significant milestone in the construction of the Chaohu-Ma'anshan Intercity Railway, paving the way for the completion of the entire railway line.

To accomplish this remarkable feat, OVM team developed a novel multifunctional hydraulic cluster control system and a visualized monitoring system. This project stands out from previous pushing continuous due to its adoption of a multi-point self-balancing pushing continuous technology coupled with an intelligent monitoring system, marking the first practical application of OVM's intelligent equipment platform. The bridge is outfitted with two main control systems, thirty sub-control systems, and one intelligent continuous pushing system, all of which collect data on displacement, load, and travel via sensors, enabling centralized control and remote visualized smart monitoring.

It has been reported that the auxiliary channel bridge of the Ma'anshan Yangtze River Road and Rail Bridge, contracted by China Railway Fourth Bureau Group, serves as a multi-functional cross-river passage linking both sides of the Yangtze River. It is one of the key projects of the Chaohu-Ma'anshan Intercity Railway. As a double-tower steel truss girder inclined cable-stayed bridge with a main span of 392 meters, the bridge comprises a total of 33 sections, spanning a length of 840 meters, divided between the Ma'anshan side and the Chaohu side. The total weight of the bridge's steel truss girders is approximately 36,000 tons, with a construction environment that is both complex and challenging.

The successful positioning of this section is a testament to OVM's technological advancements in bridge construction, setting a precedent and providing valuable insights and technical support for future projects of a similar scale and complexity.
