March 31，The main bridge of Liulu Yongjiang River Bridge in Nanyu Section of Nanshen High-speed Railway, which was built by Liugong Ovim Company, was successfully closed.。At this point，Bridge and Tunnel Works of Nanyu Section of Nanshen High-speed Railway Successfully Completed，Lay the foundation for the completion and opening of the project。

Nanyu Section of Nanshen High-speed Railway is the first high-speed railway with a speed of 350 kilometers per hour independently invested and constructed by Guangxi.，The main bridge, Liulu Yongjiang Bridge, is the largest span of the ballastless high-speed railway with a speed of 350 kilometers per hour approved for construction in the same period in China.、Steel box with the largest hole diameter for stay cables-Concrete partial cable-stayed bridge。

Liugong Owim Company provided cables for the bridge.、Cable Saddle、Anti-slip key、Steel beam hydraulic lifting equipment and other key products、Intelligent monitoring system and technical construction services。

In the process of construction，Professional prestressing construction team of Liugong Owim Company，Continuous optimization of construction scheme、Strengthen on-site control，Adopt according to the characteristics of the projectOVMSixth generation anti-slip key technology，And real-time monitor that on-site tensioning construction of the stay cable.，Ensure that the steel strand cable is uniformly stressed and the tensioning force reaches the set value.，While ensuring the safe use of the product，The functions of real-time monitoring and multiple force adjustment are added，The convenience of the later maintenance of the bridge is improved.。

With the successful closure of the Liulu Yongjiang River Bridge，The Last Breakpoint of Nanyu Section of Nanshen High-speed Railway Was Completely Opened，Track laying is fully opened、“Four electricity”And other engineering construction channels，Lay the foundation for the smooth follow-up construction。
