South Jade Railway Lily Yujiang Special Bridge smooth Heilong

On September 20th, the world's largest span speed of 350 kilometers per hour was invested and constructed by Guangxi Transportation Investment Group. A solid foundation, which marks a new breakthrough in the construction of my country's high -speed railway large span cable bridge.

The main bridge of the Lily Yujiang Bridge is a key control project of the South jade railway. It is located near Lily Town, Hengzhou, Nanning City, Guangxi. , The total length is 612 meters. There are two main towers on the east and west main bridges. The tower is 146 meters high, which is equivalent to the height of the 48 -story building. The main tower is a diamond -shaped structure and has the characteristics of large section size and heavy anchor components. During the same period of the world, the maximum span of the high -speed railway at 350 kilometers per hour was 350 kilometers per hour.

Faced with geological rock -soluble development, high tower construction difficulty, large floating crane difficulties, complicated steel mixed combination section, high -tonnage steel box beam installation of high disadvantages, etc. Regulations, continue to optimize the construction plan, focus on difficult cards, coordinate planning, fine management, and overcome difficulties.

Xie Guangyu, the head of the 5-2 Tiber Project Department of the 5-2 Tiber Project Department of the China Railway Guangzhou Engineering Bureau, told reporters: "In order to ensure the smooth construction and subsequent operational safety of the Lily Yujiang Special Bridge, we cooperated with colleges to conduct a series of scientific and technological research, including The static and fatigue test of the main body of the bridge, the study of wind-car-bridge coupling vibration research, etc., and independently develop a large change of bridge cranes to promote the safe and rapid advancement of the project.

Up to now, the base soil of the Southyu Railway Project has completed 91%of the rocks; 92%of the bridge project has been opened; 99%of the tunnel project is accumulated. The two major tunnels (Liangmu Tunnels and Pingyue Tunnel) in the five major control projects have been fulfilled. The three cross -river echo bridge Heilong has been implemented. The remaining two are steadily promoting construction. The construction of no orbit has been constructed one after another.

It is reported that after the completion of the Nanyu high -speed rail, the Nanning to Yulin itinerary was shortened from 2 hours to about 50 minutes, which will significantly shorten the time and space distance between Guangxi and the Guangdong -Hong Kong -Macao Greater Bay Area. Important and important role.
