Shocking!The mysterious train through the unmanned area is here!

This railway crosses the Qilian Mountains

Harmony, magnificent scenery

Along the way, there are both mountains, grasslands, and lakes

And the vast desert Gobi

Such rich and diverse landform scenery

It is unique in the world

This is the Dunhuang Railway

On the Dunhuang Railway

There is a special desert train

"1 member of the fixed member" per section

The speed is only 8 to 15 kilometers per hour

"Domineering side leakage"

Xiaobian will reveal the secret today

Poke the video! Shocking flight came

Super Railway Bridge through the desert

Introduction to the Stele Strait Station of the Qinghai -Tibet Railway

The total length of the line is 671 kilometers

When the route crosses the desert, the railway builders cleverly use the beam bridge to avoid wind sand from the infringement of the railway. The total length of 10.6 kilometers and the highest place is 30 meters. The Shatou Special Bridge made of more than 320 pier frames perfectly combines engineering landscape and structural functions. This is also the only special bridge through active desert in my country.

Recently, the Dunhuang workshop of the Jiayu shutdown section of the China Railway Lanzhou Bureau Group Co., Ltd. and the Jiayuguan Working section Aksey Line Workshop jointly replenished some of the Dunhuang Railway routes, including the Shathagou Bridge.

Daoma is a buffer layer between the railway track and soil road base. It not only can evenly pass the gravity of the train to the roadbed, but also controls the vertical and horizontal displacement of the track line to ensure the safe and smooth operation of the train.

The Dunhuang Railway was opened to traffic in 2019. The road base is still in a period of natural settlement. In order to improve the resistance of the lane bed and ensure the stability of the road bed, it is necessary to supplement the lack of the line. At this point, a mysterious train "shined".

"Domineering side leakage" of the wind and the car

Tian Gang was bright, and the operators were ready. They unloaded the tools from the car and entered the bridge in an orderly manner under the command of the person in charge, waiting for the arrival of unloading the car.

The task of the day was to uninstall 420 cubic meters of stone pupa in 120 minutes, covering 3.5 kilometers of lines.

Wind downside vehicle is a dedicated coverless funnel. The inside of the vehicle is "W" type, consisting of the vehicle body, unloading system, brake device and other parts. Essence

Different from ordinary freight trains, in addition to loading the Taoist cars, each vehicle of the wind downswing vehicle has an operation room, equipped with a staff member to control the valve operating rod, and open the bottom of the unloading door according to the timing of the unloading progress.

During the homework, the person in charge of the unloading was united with the person in charge of the scene and the locomotive driver to open the bottom of the wind.

The seemingly simple collaboration tests the driver's driving skills of the train driver. Due to the continuous weight of the vehicle's body weight during the unloading process, the traction of the locomotive must also change accordingly. It has high requirements for the speed control and stable control of the train.

When unloading the operation, the train needs to keep running at a constant speed, so as to avoid the situation of the tunnels or insufficient replenishment, and ensure that the tunnels are evenly fell on the tunnel bed.

Through the observation holes of each compartment, the operators can check the remaining situation of the stone pupa in the compartment. When the stone pupa in the carriage is about to unload, then contact the next car to continue the operation.

After the unloading, the operators also need to organize the appearance of the road bed, rectify the problem of stone 砟 restrictions, and use the side bed to check the car to check the restrictions of the stone 砟 to ensure the normal operation of the train.

The supplement to the Shi Yan's work lasts nearly 20 days

150 kilometers of work mileage

Add 7600 cubic meters

Poor deserted birds do not fly

Iron Dragon Flying Settles

Railway people are like Zagen Gobi

Camel grass usually sticks to the uninhabited area day after day

Ensure that the Dunhuang Railway is safe and smooth
