On June 16th, with the opening of the He Ruo Railway, the world's first ring desert railway line was closed. During the construction process of more than 3 years, it extended with the railway with nearly 300 kilometers of windproof sandwiches. The deserted desert has grown a green promenade, protecting the Taklama Ganan Desert, known as the "Sea of ​​Death".

The total length of 825 kilometers and the Ruo Railway, about three -quarters of the roads cross the desert and Gobi, the distribution length of the wind and sand section exceeds 500 kilometers.

On the afternoon of June 13th, in the end of the county and the Ruo Railway Road base, the China Railway First Hospital Group Xinjiang Railway Survey and Design Institute Co., Ltd. and the head of Ruo Railway design Zhao Jiahai pointed to the sand dunes not far away and told reporters: "The flowing sand dune is right The line is most harmful. The sand grains enter the road, filling the gap between the roads, causing the Taoist plate to lose shock absorption effect. Therefore, the footsteps of the dune must be blocked. "

The desert is repaired by the railway. The most long -term effect of sand control is that a large number of trees and shrubs are planted outside the line.

How can we prevent pervasive fine sand? The builders moved their brains, and the designer adopted a sandproof mode of "external resistance inner and internal high and low inside". The reed sand barrier and reeds are set up from the outside to the inside in turn on both sides of the railway. The vegetation strip composed of shrubs ranges from 110 meters to 400 meters. Before the plant grows up, a 1.5 -meter -high vertical sand barrier is blocked by the outer side. The inner side is set to a reed square grid with a height of 0.3 meters high and a total area of ​​50 million square meters. system.

Between the obstacles and the grass grid, nearly 13 million trees such as shrubs and euphratica that are easy to grow in the desert, and the forest belt covers an area of ​​more than 110,000 mu.

With the erosion of the wind and sand, the sand barrier and the grid will gradually fail after a few years, but the longer the plants will be higher and higher, it can play the role of sand prevention. Fixed flow sand.

The most important thing about plant sand prevention is water. Without water, the protective forest cannot be planted successfully. "During the survey, we found that in fact, there are more groundwater in the Taklimanan desert, and the water quality is also suitable for plant irrigation." Zhao Jiahai said.

The builders hit a total of 131 water sources, with a maximum depth of 280 meters and an area of ​​1135,000 acres. It solved the problem of water shortage in plant growth in the desert.

When I walked to a water source well, Zhao Jiahai said: "After the groundwater is pumped, enter the drip irrigation system. After the intelligent control of the administrator, drip it into the root of the plant to let the plant drink enough water."

After more than 3 years of hard work, today, the wind -proof sandwiches of nearly 300 kilometers are green and vibrant, like the Great Great Wall, protecting the railway safely.
