The Sichuan-Tibet Railway under construction starts from Chengdu to the east through Ya'an, Nyingchi and other cities and finally arrives at Lhasa. It travels long distances, through mountains and ridges, and the snow-capped mountains, forests, grasslands, glaciers, canyons, and large rivers along the line are in the eyes of ordinary people. The magnificent scenery, but for the railway builders, what is more touching is the thrilling and steep terrain. "The road to Shu is difficult, and it is difficult to climb to the sky." The construction of the Sichuan-Tibet Railway, the second snow-covered plateau sky road, is even more difficult.

High-quality high-quality equipment battles the plateau

When the Qinghai-Tibet Railway was built twenty years ago, people had already seen the harsh infrastructure conditions on the Qinghai-Tibet Plateau: permafrost, fragile ecology, high cold and lack of oxygen, etc. These problems still exist in the construction of the Sichuan-Tibet Railway. Due to its location on a plateau with an altitude of 3,300 meters, the construction party has become particularly cautious in the selection of construction equipment, because the traditional oil-fired excavator has a power drop due to insufficient pressure, which leads to a reduction in construction efficiency, which will seriously affect the progress of the project.

In the face of the super project with the most complicated terrain and geological conditions in the history of railway construction in the world, XCMG consciously assumes the responsibility of a major power and dispatched the XE215E and XE270E electro-hydraulic excavators that condense the latest technological innovations to bravely fight. XCMG's top service technical team is also stationed here for a long time, standing by 24 hours a day, only to ensure the normal operation of the equipment, and to provide a strong guarantee for the Sichuan-Tibet railway construction project.

“On the plateau at an altitude of 3,300 meters, many excavators are difficult to construct at all and are prone to various failures.” Hu Ju, the operator of the Kangding Paomashan Tunnel Project, exclaimed, “Fortunately, XCMG’s electric excavators are very easy to use this time. , If you want to score, I want to give five stars!"

What Hu Ju drives is XCMG’s XE215E electric excavator, which is purely electric driven and has undiminished power on the plateau. It is combined with the XE270E electric hydraulic excavator. It has superb battery life and has been working for more than 1,200 hours without any problems. Even in the face of "the most difficult railway to build", it still performed well. In addition, zero emissions, no pollution, and great protection of the ecology.

Aiming at the relatively narrow working space of the tunnel, XCMG technicians specially made improvements to the equipment by shortening the large and small arms and narrowing the counterweight, so as to easily realize flexible operation. And the unique cooling design, without fear of the extreme temperature difference inside and outside the tunnel, greatly guarantees the safety and comfort of the driver.

Before making the decision to purchase XCMG pure electric excavators, Zhang Tianen, the person in charge of the Paomashan Tunnel project with extensive equipment management experience, conducted a comprehensive inspection of the stability, safety, and intelligence of the product. "XCMG is The brand I have always trusted, the performance of XCMG’s new products this time really did not disappoint me.”

Excellent service, fully guarantee no worries

The Sichuan-Tibet Railway has to cross the first and second steps of China, as well as the Hengduan Mountains, the most majestic mountain range in the world. As one of the most important seismic zones in China, it not only has frequent earthquakes, but also the geology is very complex. There are faults in the middle of the mountains, plateau lakes above, and groundwater below, avalanches, streaks, landslides, earthquakes, geothermal, karst caves, underground rivers, According to statistics, there are more than 1,000 geological hazards along the route. How should this road be repaired?

"For the problems that may be encountered, we have made sufficient understanding and preparations before the start of the project." Talking about the difficulties encountered by the project, Zhang Tianen frowned, "But the current problem of groundwater flooding is still a headache."

The problem of groundwater flooding has always been one of the difficulties in tunnel construction. Although advanced geological predictions have been made on the site before construction, it still occurs from time to time. "Every time the groundwater floods, it will cause harm to the construction personnel, construction equipment, and the tunnel itself. However, XCMG's service engineer team always appears on the scene as soon as possible to overhaul the equipment. There has been no delay in the construction period due to equipment failures. Like them for the situation!"

Liu Bin, XCMG's top-notch gold service engineer, is among this list. "I used to stay in the north and suddenly came to the southwest. I was still in a high-altitude area. I was a little uncomfortable, but now it's completely fine." In an understatement, there are countless gritted teeth behind him.

In order to solve the problem that the number of charging piles is not enough to meet the demand, work overtime until late at night to urgently install; in order to ensure the efficient attendance of the equipment for construction, it is on call 24 hours a day; in order to solve the problem more efficiently, seize the work gap to learn new knowledge by yourself... Liu Bin and other service engineers have become accustomed to extreme working environments such as groundwater, high ground temperature tolerance, and high altitude hypoxia.

Chengdaqi XCMG highlights brand responsibility

The Sichuan-Tibet Railway shoulders the collective dream of the three generations of railway builders in China. After completion, it will become another major artery from the roof of the world to the inland after the Qinghai-Tibet Railway. Premier Li Keqiang once said affectionately during the inspection of the construction site of the Lalin section of the Sichuan-Tibet Railway: “The Sichuan-Tibet Railway will not only shorten the space and development distance between Tibet and the inland, but also the psychological distance between each other. The Sichuan-Tibet Railway will contribute to the development and construction of Tibet. Ecological protection is of great significance. It is not only the expectation of the Tibetan people, but also the wish of the people of the whole country."

The construction of the Sichuan-Tibet Railway is a major measure to implement the Party Central Committee’s strategy for governing Tibet. It can itself play a role in strengthening ecological protection and preventing soil erosion. More importantly, this heavenly road has important and direct significance for promoting national unity, consolidating border stability, improving the layout of Tibet's transportation network, and injecting vitality into local economic development.

After the opening of the Sichuan-Tibet Railway, this mysterious land of Tibet will merge from the roof of the plateau, like three parallel rivers, into the Chengdu-Chongqing Shuangcheng Economic Circle and the Yangtze River Economic Belt. Therefore, to a certain extent, Sichuan-Tibet The railway has become a landmark project for the development of the western region in the new era, and has laid a solid foundation for Tibet to realize internal and external connections and integrate into the One Belt One Road.

"Great responsibility, great responsibility, far-reaching road", XCMG assumes the responsibility of the great power of the country, and provides an overall solution to meet the needs of the construction of the Sichuan-Tibet Railway-the electric excavator is firmly in the front, and the service engineer team is guarding side. This is the super project of the super power, and the great responsibility of the great power. Editor/Sang Xiaomei
