The Guidan High -speed Railway runs through the northwest of the Guangxi Zhuang Autonomous Region and southeast of Guizhou Province. The total length is 482 kilometers. The main line is 964 kilometers. Among them, 564 kilometers of rails in the Guangxi section. According to the arrangement of the construction organization, the paving rails of the Guangxi section of the Guidan high -speed rail will be carried out in the order from south to north. The tasks are paved from Hechi to Nanning. Complete the Guangxi section.

In order to ensure the construction quality and efficiency of the Guangxi section of the Guangxi section of the Guinan high -speed rail, the Guangxi Railway Guangxi Company and the China Railway 14th Bureau improved the rail labeling process, and used the current advanced multi -line rail paving all -in -one machine and traditional rail paving equipment to make the Gui Nan high -speed railway. The long steel rail laying of the two lines of the uplink and downlinks is carried out simultaneously. There is no need to change the equipment to the device, and the efficiency has been increased by 50%compared to the past. This rail paving process is still used for the first time in the history of the Guangxi Railway. The construction unit also adopts the intelligent driving dispatching command system to monitor and unified dispatch commands of the operating status and operating position of the equipment, long track transport vehicles, and welding vehicles all day to ensure that the cross construction is safe and orderly.

The double -block pillow is an important part of the Guidan high -speed rail no -paine bed, which plays an important role in improving the quality of the rail paving and ensuring the safety of train operation in the future. In order to ensure the quality of the pillow production, the construction unit has built China's first automatic digital simulation dual -block pillow smart factory -the Guinan High -speed River Pond Pillow Pillow Pillow Pillow Pillow Pillow Pillow Pillow Pillow Pillow, and the 889,000 railway pillows required by the Guinan high -speed railway are all computers and Intelligent robotic arm control complete production. The error of the pillow can be controlled within 0.5 mm. After the production of each track pillow is offline, the size, height, laying section and other information will be uploaded to the large database of the background system simultaneously, which will be based on the foundation of the pillow, and provide a basis for the construction operation.

The Gui Nan High Speed ​​Rail is an important part of the central package of the "Eight Eights and Eight Heng" high -speed railway network in China. It is also the first high -speed railway with a design speed of 350 kilometers per hour in Guangxi. The entire line is expected to be opened at the end of 2023. At that time, the passage of Nanning to Guiyang will be shortened from more than 5 hours to about 2 hours, which will be of great significance to promote the transportation, logistics, commerce, and industrial depth of the two provinces and regions of Guizhou and Guizhou.
