Gui Nan High -speed Railway Laurea Laureate Chengdu 6 hours to run to Nanning

At 10:18 on August 26th, with the first pair of 500 -meter long rails smoothly laid on the Xin'an Double Line Bridge in Duyun City, Guizhou Province, marking the official entering stage of the Guonan high -speed rail, which is smoothly entering the rail paving stage. The opening of operations laid a solid foundation. After the Guinan high -speed railway was opened to traffic, the railway travel time from Chengdu to Nanning will be theoretically compressed to less than 6 hours.

The Guinan High -speed Railway runs through the southeast of Guizhou Province and the northwest of the Guangxi Zhuang Autonomous Region, with a total length of 482 kilometers, of which the Guizhou section is about 199.6 kilometers long. It started in the early days of December 2016 and started in February 2019. The entire line was about 18.2 kilometers. About 52.9 kilometers and 63 tunnels are about 128.3 kilometers, and the bridge -tunnel ratio is 91%. Two new Du Shandong and Libo Station Rooms are built, and 3 stations in Longli, Guiding County, and Duyun East. At present, the "four power", station building projects, and rail paving after the project station have been fully launched, and various projects are promoting in an orderly manner in order of planning nodes.

In order to accelerate the construction of the Guizhou section of the Guidan high -speed rail and ensure the opening of the project as scheduled, and help the local economy achieve high -quality development, China Railway Chengdu Bureau Group Co., Ltd. and various participating units have always adhered to "the epidemic should be defended, the economy must stabilize, the development must be developed. The overall requirements of safety, formulate detailed construction plans, carefully organize, coordinate and cooperate, and go all out to organize the implementation to ensure that the project construction is safe and orderly. According to professional transportation and management models, the construction unit has invested more than 700 operators and mobile flashing equipment and other automated engineering equipment such as operators and mobile flashing welding machines to overcome the high temperature, large bridge and tunnel, large line slope, and small operating space. Negative Effects.

At the same time, organize and carry out an emergency drill of toxic and harmful gas poisoning of rail engineering internal combustion locomotive tunnel paving operations, with emergency items such as oxygen cylinders, anti -virus masks, and quick -acting savior pills. By adopting ventilation equipment on the construction vehicle The detector measured the tunnel gas for 24 hours to further ensure the safety of the rails in the tunnel.

In addition, the engineering line management scheduling and command center is specially set up, unified command, unified coordination, and unified scheduling, and the operating status and work position of large -scale equipment such as internal combustion locomotives, rail paving units, long steel rail transport vehicles, and mobile flashing welding machines are monitored in real -time monitoring Ensure the construction quality and efficiency of the Guizhou section of the Guizhou section of the Guizhou section.

"We took the lead in investing in a new type of long rail tractor with automatic rails and cross -line transfer. Compared with the traditional construction process, laying one pair of 500 -meter long rail can reduce 2 operators, saving about 20 minutes of operating time. The relevant person in charge of Guizhou Co., Ltd. of the Shanghai -Kunming Railway Passenger Line introduced.

It is understood that the Guonan high -speed rail is an important part of my country's "eight vertical and eight -horizontal" high -speed railway main channel Baotou to Haikou Channel, with a design speed of 350 kilometers per hour. After the entire line is completed and opened to traffic, the running time from Guiyang to Nanning will be shortened from more than 5 hours to about 2 hours, and it will be connected to high -speed railway such as Shanghai -Kunming and Chenggui. The main channel for convenient and fast passenger transport in the west and Hainan region. At present, the fastest travel time of the Chengdu Nanning Railway is 8 hours and 51 minutes, and the fastest to Guiyang from Chengdu to Guiyang is 3 hours and 4 minutes. After the Gui Nan high -speed railway is opened to traffic, the theoretical railway travel time from Chengdu to Nanning will also be further shortened to less than 6 hours.
