The main project of the Fuxia High -speed Railway is through the entire line!

The last hole prefabricated box beams of the Fugia High -speed Railway Xiamen Jimei Bridge are completed.

Yesterday afternoon, as the last hole prefabricated box beam was smoothly located in the bridge pier 193-194, Xiamen Jimei Bridge, the first domestic high-speed rail high-speed rail high-speed railway main project in the sea announced that it was one step closer to the entire line.

The Fuxia High -speed Railway starts from Fuzhou South Station in the north and Zhangzhou Station in the south, with a total length of 277.42 kilometers. Overlooking from the air, the main body of the Fuxia high -speed rail is like a white dragon flying across the mountains and winding. According to the construction unit of the Sixth Bureau of China Railway, the prefabricated box beams were 32.7 meters long, 11.6 meters wide, and 3.03 meters high. The weight reached 900 tons, which belonged to the "big block" in the prefabricated box beam.

It is reported that the construction of the upper structure of the Fuxia high -speed railway is expected to be completed by the end of the year, and the entire project is expected to be officially operated in the second half of next year.

The prefabricated box beams of the Fudia High -speed Railway were stored in the Fukui Liangchang 20 kilometers away from the construction site, transported long -distance transportation, and went through the tunnel four times. Usually the design width of the high -speed rail tunnel is 12 meters, that is, when the box beams with 11.6 meters wide cross the tunnel, the left and right sides are only 40 cm.

Li Jianxue, manager of the project department of the Sixth Bureau of the China Railway Bureau, introduced the difficulty of the project. The construction adopts the most advanced 1,000 -ton separation grid equipment in China. In conjunction with the precise positioning of the Beidou navigation satellite "". Under the guidance of satellites, the driverless system can control the vehicle to turn the vehicle to correct the deviation in real time. During the operation, the body can maintain the range of 8 cm in the central line, ensure safe transportation, and effectively improve the efficiency of beams crossing tunnel.
