2024-07-04 11:32:00

 Nanji Gate Rail Bridge is the first large-scale use of steel spring floating plate ballast in China. When the train passes over the bridge at high speed, the integral ballast of the steel spring floating plate can not only reduce the noise of the train, but also reduce the vibration of the bridge floor. The monitoring system monitors the vibration, main beam stress and environmental load of the bridge in real time.
