On the 9th, the reporter took the first train to experience part of the way.
The Ge-Ku Railway is 1,206 kilometers long, part of Golmud City, Qinghai Province, passing through Ruoqiang and Yuli counties in Xinjiang, passing through the Taklimakan Desert and Kumtag Desert and ending in the city of Korla. The Xinjiang section is 734 kilometers long and the windy sand section is 390 kilometers long. Wind sand, Gobi sand flow, and wind erosion are common.

To this end, we have taken various measures, such as windproof engineering and fixing sand and plant fixation “. Said Feng Dequan, chief design engineer for the Geku railway project.
From Yuli County to Ruoqiang County, the Ge-Ku Railway runs through the western edge of the Taklimakan Desert. On the way the reporter saw that the railway bed stood like a thorn in the desert, and the squares of reeds on either side stretched out endlessly. “Using local reed stalks, a windproof and sand-fixing ‘Great Wall’ was built nearly 400 kilometers outside the railway to block most of the sand off the railway,” said Feng Dequan. In addition, to know the sand accumulation situation on the road section in time, the Gekko Railway has also established a real-time monitoring system for sand control. Install cameras along the line to “watch”. the windy and sandy section like a clairvoyant to ensure the safety of the trains.
In addition to overcoming the severe challenges of wind and sand, how to protect the ecological environment along the route is another difficult problem for builders.
“The Ge-Ku railway runs through the Populus euphratica primeval forest reserve, the wild camel national nature reserve and the Lake Taitma wetland, etc. The animal and plant resources along the line are rich. At the beginning of the selection of the route, we avoided and stayed away from wild animal activity areas in many places. The area overlooks the Populus euphratica forest, the national public welfare ecological forest and the windbreak forest belt, etc. “said Feng Dequan .
When the train arrives at Lake Taitma, the scenery outside the window will attract the attention of the passengers. The blue lake began to freeze and the water birds flew in the reeds in the distance, forming a unique image in the desert.
The Lake Taitma Bridge spans the lake area from south to north and is the longest railway bridge in Xinjiang. “In order to protect the ecological environment of the lake, we abandoned the most cost-effective way of passage over the road bed and adopted a viaduct to cross the lake area. The bridge design was extended from the original 7.5 kilometers to 15 miles. Not only does it ensure the natural flow of the lake, but it also provides for the wild animals that live in the lake area. Please leave the crossing passage. ” Feng Dequan introduced.

A total of 31 bridges with a height of more than 5 meters have been built in the reserve to facilitate the passage of animals and try to avoid the impact on the migration of wild animals.
“The Geku Railway is a green and environmentally friendly main artery in and out of Xinjiang, and it is also the first railway project in Xinjiang to introduce an environmental monitoring system, achieving” mutual benefit “in railway construction and ecological protection “. China Railway Urumqi Bureau Group Co., Ltd. Party Secretary Tang Qingshan said. (End up)
