Ge-Ku Railway’s first sand control experience has tricks to “protect the green”

Original title: Ge-Ku Railway first experience in sand control and “preservation of the green”

GakurailwayAfter the Xinjiang section was officially opened to traffic, Xinjiang added another railway from Xinjiang. 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.

“Even if we bypass a large area during the route selection process, more than half of the road sections have varying degrees of sandstorm. To this end, we have taken various measures, such as windproof engineering and fixing sand and fixing plants “. China Railway First Survey and Design Institute Group Limitedthe companyDirector of railway project design at GekuengineerFeng Dequan said.

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 primeval Populus euphratica Forest Reserve, the Wild Camel National Nature Reserve and the Lake Taitma Wetland.SuppliesRich font. At the beginning of the route selection, we avoided and stayed away from wild animal activity areas in many places, largely avoiding Populus euphratica forest, public welfare ecological national forest, and windbreak forest belt. Feng Dequan said.

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. “To protect the ecological environment of the lake, we abandonedinvestmentA more economical way of passing through the road bed, the use of viaducts through the lake area,bridgeThe design ranges from the original 7.5 kilometers to 24.5 kilometers.WarrantyThe natural flow of lake water leaves a path for the wild animals that live in the lake area. Feng Dequan introduced.

When the train passed through Xinjiang’s Lop Nur Wild Camel National Nature Reserve, the reporter noticed that this section of the railway mostly passed over bridges. 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.

“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 environmental protection supervision system, achieving mutual benefit in railway construction and ecological protection ”. China Railway Urumqi Bureau Group Co., Ltd.TreasurerTang Qingshan, secretary of the Erle Railway Construction Command Party Committee, said.
