The first mock exam of China’s five railway construction of the China Railway Bureau, the 1 love tunnel in the No
.
1 inclined shaft of the anding tunnel, was completed in February 21, 2021, marking the completion of the first long tunnel ballastless track of the first long tunnel
.
The Land Rover has cleared the entire track and has created favorable conditions for ensuring smooth opening of the old fellow railway line
.
Anding tunnel is the most important and difficult project of Kunming Wanzhou railway between China and Laos, which integrates water gushing, fault, high rock temperature and other unfavorable geology
.
Since the first one belt, one road construction project, the 8822 railway project of the five Railway Bureau of the China Railway Corporation, which has undertaken the construction task of the entrance of the tunnel, has been able to overcome the difficulties of important nodes on the key lines since the first ballastless track construction in September 23, 2020
.
In the construction of railway anding tunnel, we should optimize construction organization, overcome difficulties, carry out labor competition, and launch a sprint to each node goal
.
Ballastless track is the last process of railway construction
.
In order to get through the last blocking point before track laying and to reach the track laying conditions as soon as possible, more than 300 builders who undertake the construction task under the exit line of Anding tunnel “do not close” during the Spring Festival
.
During the Spring Festival, they stick to their jobs and spare no effort to seize the construction
.
Through continuous operation day and night, the builders ensure the smooth completion of the main works under the exit line of Anding tunnel
.
At present, 4.3 km of track has been laid on the right side of Anding tunnel entrance, and the track laying work is progressing at a rate of 5 km per day
.
China and China are China’s first one belt, one road initiative, the first railway line with Chinese investment, the Chinese standard is adopted on the whole, and the international railway is directly connected to China railway network, with a total length of more than 1000 km
.
The project is expected to be open to traffic in 2021
.
After the completion of the project, from Kunming, China to Vientiane, Laos, it is expected to achieve the goal of overnight arrival.
