The construction of Yiliang Tunnel, the control project of Chongqing-Kunming High-speed Railway, will not be suspended during the Spring

The vehicles and drivers for transporting raw materials and waste slag on the construction site should be recruited and rented from the local as far as possible, which not only solves the employment of local surplus labor, but also ensures the normal construction and production at the construction site.

The production needs us to stay and continue to work, not to mention to prepare delicacies and delicacies for everyone, but hot dishes and hot meals are the basic requirements.

Each family prepares several specialty dishes, and the strong flavor of the Spring Festival ripples in the station far away from home.

At the beginning of the new year, the construction tasks and indicators are very heavy.

After the construction of the advance support team, it is the turn of the excavation team.

The tunnel is constructed 24 hours without interruption.

Yiliang Tunnel is the world’s longest high-speed railway tunnel currently under construction with a speed of 350 kilometers per hour.

Near the Spring Festival, in order to build the railway as soon as possible and benefit the local people, many construction sites of the railway do not stop work, and thousands of railway builders choose to celebrate the New Year on the spot.

“We got married in June, 22.

January 21 is New Year’s Eve.

During the Spring Festival, the reporter visited the Yiliang Tunnel of the Chongqing-Kunming High-speed Railway.

More than ten days ago, his wife Xu Lin came to the project site with her 6-year-old son to celebrate the Spring Festival with him.
.

2 inclined shaft is located at the bottom of the valley with a longitudinal height difference of 600 meters.

Due to the geographical environment, the access of mechanical equipment, raw materials and waste slag hauling are all obstacles restricting the progress of the construction period.

Due to the tight construction period, the Yiliang Tunnel did not stop during the Spring Festival.

Hang lanterns and paste Spring Festival couplets.

We give the opportunity to go home for the New Year to colleagues with children and older parents.

“The construction site is located in a remote place, and the conditions are a little poor.

With the entrustment of the Party Central Committee and the expectations of the local people of all ethnic groups, thousands of railway builders moved and gathered here.

In 2019, the construction of the Yunnan section of the Chongqing-Kunming High-speed Railway was started.

From more than 10 days before the festival, he checked the number of people left behind with each work site as soon as he was free, contacted to buy rice and vegetables, and occasionally followed the purchase car to the small town outside the city to purchase.

It has large slope, rich water and obvious signs of surrounding rock compression.

Wang Xutao and them came to the tunnel face to check the night shift operation.

The entrance of the tunnel No.

It will be more memorable to stay at the construction site for the first year of marriage.” Song Yaming, Wang Xutao’s wife, said with a smile.

Foot Eye Anchor

Yiliang Tunnel is the key control project of the whole line, and the time of tunnel connection restricts the time of completion and opening of the whole line.

According to Wang Xutao, this year is the dry year of Chongqing-Kunming High-speed Railway.

During the Spring Festival, there were more than 400 constructors in the second work area of the Yunnan-Guizhou Section of the Chongqing-Kunming High-speed Railway.

For a moment, the wheels rolled, the machinery roared, and the silent landscape boiled.

In fact, we can see each other once a week.

The tunnel is mainly composed of Grade IV and Grade V surrounding rocks, with unfavorable geology such as fault fracture zone and high ground stress.

Many builders have made arduous efforts to this end.

Once the picture is released, the access road built for the construction needs has become a network red punch card place, which is vividly known as “13 turning spots” by netizens.

Wang Xutao, 28, is the on-site technical director of the No.

“Lao Wu, the surrounding rock condition of this section of tunnel face is not very good, so it must be explained well when taking charge of the shift.

At present, each construction site of Yiliang Tunnel has entered the main tunnel construction.

The construction site is also the Spring Festival.

At this time, the technical backbone of the project department turns into a “chef”.

The terrain is extremely steep and prone to earthquakes and landslides.

The depth of the blasthole and the amount of charge must be strictly controlled, and the change of surrounding rock strata should be paid attention to at any time, and pay attention to safety.” In front of the head of the No.

If you look at it on the spot, you can have a comprehensive grasp of the progress, quality and process connection of the night shift, and you will have the confidence to arrange and organize the construction and production of the day.” Wang Xutao explained.

Wang Xutao’s wife, Song Yaming, was the site documenter and was responsible for the collection, summary and compilation of the project data.

It is located in the heart of the Wumeng Mountains, with high mountains and deep valleys.

It is a double-tunnel single-track tunnel with two tunnels, The left line tunnel is 24.78 km long and the right line tunnel is 24.8 km long.

According to statistics, during the normal construction period, more than 300 local workers participated in the construction of Yiliang Tunnel, and more than 60 transport vehicles were rented, which strongly supported the local economic and social development.

It is a control project for the whole line of the Chongqing-Kunming high-speed railway.

He learned that he cannot go home for the Spring Festival.

Yiliang County, Zhaotong City, Yunnan Province, is located in the hinterland of Wumeng Mountain, where mountains are high and valleys are deep, and traffic is the biggest obstacle to the local economic and social development.

In the face of complex geological problems and tight construction period requirements, the builders split the mechanical equipment into parts and transported them to the construction site for assembly.

Although we are in the same project department, he is in the work area and I am in the project department.

After the Spring Festival, the “family kitchen” of the project department is much more lively than before.

Although the couple were on the same project, there were not many opportunities to meet.

It is only one day to buy a dish to go in and out.

Do a good job in logistics, so that everyone can be fully involved in the construction and production, and improve the internal power to speed up the construction.” said Zhang Chenkui, the secretary of the second working area of the Chongqing Kunming Project Department of China Railway Construction and Bridge Bureau, who is helping the kitchen in the canteen.

“Tunnel construction is a continuous cycle of process after process, and each process can’t be sloppy.

He is also one of the left-behind staff this Spring Festival.

The construction access road built according to the mountain has 13 turns.

2 inclined shaft of Yiliang Tunnel, Wang Xutao repeatedly told the foreman Wu Kai.

The deputy manager Yang Jinqiang’s home is far away in Hailin, Heilongjiang Province.

In order to ensure the smooth access of mechanical equipment, raw materials and tunnel waste, a 7.5 km long access road must be built from the top of the mountain.

In order to open the tunnel as soon as possible without affecting subsequent construction.

The problem of construction and production has been solved, but the problem of food for more than 400 left-behind workers has made Zhang Chenkui, the secretary of the work area, a little anxious.

As usual, Wang Xutao got up early and began his busy day.

His company, China Railway Construction and Bridge Bureau Group, is responsible for the construction of the Yunnan-Guizhou section of the Chongqing-Kunming high-speed railway.
