On July 16, the railway climbed to the western Sichuan Plateau for the first time. At 10:18 that day, in the Chengdu -Lanzhou Railway Chengdu to Chuanzhu Temple (Huang Shengguan) (hereinafter referred to as the Chenglan Railway Chengchuan section), the first group of 500 -meter long steel rails fell steadily, marking Chenglan Lanlan The railway Chengchuan section began the plateau section of the plateau section, and the construction of the entire line entered the tackling stage.

The rail traction vehicle leads the long track through the Chenglan Railway Gaichuan Station

The Chenglan Railway is an important part of the national "eight vertical and eight horizontal" high -speed rail network. It is another "sky road" built in my country after the Qinghai -Tibet Railway. The Chengchuan section, which was first built in the test section, started in Qingbaijiang, Chengdu. It passed the main Temple of Sichuan, from Shiro, Mianzhu, Anzhou, Maoxian to Songpan, and climbed from 600 meters to 3200 meters. Essence At present, the paving rails of the Chengdu Plain area have been completed and are promoted to the Plateau western Sichuan.

At 8 am on the morning, the long -track special ranks carried 9 pairs of long tracks with a total length of 4.5 kilometers. "General long tracks carry 14 pairs and 7 kilometers long track." Zhang Hua, executive deputy commander of the Chenglan Railway Engineering Headquarters of China Railway Eighth Bureau, introduced that the plateau segment entered this rail pavement, the largest line of the line was 17.8 ‰ It is equivalent to a mileage altitude of 17.8 meters in a mileage altitude. The rail label vehicle will always be climbing. The long -track special line has to "lose weight" to "climb" to the plateau.

Under the traction of the rail traction vehicle, the steel long track is like soft noodles, gently falling on the no -rails, sliding forward with the traction, rubbing with the steel rail buckle, making a crisp "哐哐" sound.

After the Gaochuan Station and entering the Yuelongmen Tunnel, the first group of 500 meters long track fell steadily. At this time, the tail of the long track was still in the persimmon garden tunnel. A long track spans the "two tunnels and one station"! Chenglan Railway Corporation Chenglan Commander Xiao Xialin said that from Gaochuan Station to Songpan Station, it will enter the tunnel group of the Chenglan Railway. The mileage of 145 kilometers, the tunnel accounts for 96%.

Construction staff tightened the rails just paved

The growing tunnel group brings a lot of challenges to the rails: the operation space in the tunnel is narrow and the operating environment is poor. It is necessary to overcome many difficulties such as tunnel communication, ventilation, and long -sized road transportation. For example, the Yuelongmen Tunnel still exists after the penetration of the "seasonal wind", which will lead to a sharp increase in harmful gases in the cave in a short period of time. The internal combustion locomotive used by the rail vehicle will produce a large amount of carbon monoxide. Come to harm.

Wang Hailiang, commander of the Chenglan Railway Engineering Headquarters of China Railway Nineteenth Bureau, introduced that the Yuelongmen Tunnel has formulated a special ventilation plan through on -site trials to form a toxic and harmful gas generated during the discharge of rails. At the same time, the rail paving vehicles are equipped with toxic and harmful gas purification devices, ventilation equipment, monitoring equipment, etc., and are equipped with anti -virus masks and oxygen masks for construction workers.

The railway has been paved with the Chenglan Railway Gaochuan Station. The station is located between the Persima Garden Tunnel and the Yuelongmen Tunnel. Chenglan Railway Company Photo Conferry

According to Xiao Xialin, the Chenglan Railway is currently across the line. The Disheng Tunnel in Songpan is not yet connected. In order to accelerate the construction progress, the pavement of the plateau section will be carried out at the same time at both ends of the Disheng Tunnel. In other paragraphs, it is expected to be opened to traffic in 2023.
