Qinghai **Rong**Reporter Ni Xiaoying.
Starting from Xining all the way to the southeast, the snow-covered mountains are covered in silver, and against the background of the blue sky and white clouds, it is like a magnificent and vast ink painting. The plateau in early spring was cold and windy, however, when the reporter came to the construction site of the 10th section of the Xining-Chengdu Railway contracted by the First Harbor Engineering Bureau of CCCC, he felt another "temperature".
As soon as I arrived at the site, I saw several construction workers wearing blue overalls and red hard hats holding tape measures, flashlights, cameras, etc., seriously conducting safety inspections.
On the 27th of December, more than 40 colleagues in our project department stuck to their posts and insisted on conducting comprehensive safety inspections on the site every day. Liu Bolin, secretary of the Party branch of the Xicheng Railway Project Department of CCCC First Harbor Bureau, saw the reporter, and half-jokingly and half-seriously "stated": many of his colleagues, like him, were ready to stick to the construction of this plateau railway until the "last moment".
I got up at 6:30 in the morning, arrived at the office on time at 7 o'clock, and wrote today's work content and key work in Liu Bailin's work diary. At 7:30, the meeting was held on time to arrange the focus of the day's work and inspection requirements. After inspecting key areas every day and monitoring and rectifying various potential safety hazards, a safety inspection review meeting will be held on time at 18 o'clock on the same day to understand the inspection situation of each site. In the "two points and one line" round trip between the project department and the construction site, not only during the Spring Festival, he has insisted on such a work rhythm for more than 400 days and nights.
The tunnel construction site of CCCC First Harbor Engineering Bureau.
There is no room for sloppiness in the construction of this railway project for the benefit of the local people, and we must devote ourselves wholeheartedly. Liu Bailin said.
The Xicheng Railway has attracted the attention of all parties since the day of the official start of construction. It is a part of China's "eight vertical and eight horizontal" high-speed rail network Lanzhou, Xining to Guangzhou's Lanzhou (West) Guangzhou Channel, along the line and has been opened Lanxin high-speed railway, Xi'an to Chengdu high-speed railway, Chengdu to Guiyang high-speed railway, Chengdu to Chongqing high-speed rail and under construction Lanzhou to cooperative high-speed railway, Chengdu to Lanzhou high-speed railway, Chengdu to Dazhou to Wanzhou high-speed rail and other lines connected, the road network status is very important. After the completion and opening of the whole line, it will further strengthen the urban agglomeration of Lanzhou (Zhou) and West (Ning) and the city of Chengdu and Chongqing, promote the interconnection of the "Silk Road Economic Belt" and the "Yangtze River Economic Belt", promote economic and social development along the route, and help rural revitalization.
Yan Zhongwei, director of the Engineering and Technology Department of the Xicheng Railway Project Department of CCCC First Harbor Bureau, used several data to illustrate the complexity of the on-site construction in the bid section: tunnel construction accounted for 963%, of which the total length of the Dangshun tunnel is 1349 kilometers, equivalent to 33 standard track and field fields, designed as a single line and two holes, has been fully drilled, and all construction and production are advancing in an orderly manner.
Not far from the tunnel exit is the Smart Mixing Center of Section 10 of the Xicheng Railway, which is called "Wisdom" because there are only two workers on duty every day, and they control the production of concrete required for construction through computers. I saw that they skillfully pressed different buttons such as red, yellow, and green, and the monitoring screen displayed a series of operations in the concrete production workshop to "listen to the command", from issuing the production task list to arranging the tanker in place, and then to the inclined belt, the flat belt ringing to start, start the production of mixed concrete, and finally discharge, the whole process, there is no one in the production workshop.
Such an information control center, we have 5 bids, and the raw materials required for the project have basically realized intelligent production, which is not only reliable in quality, but also saves time and effort. Liu Bailin said proudly.
Xia Wucairang, an on-site technician, told reporters that there is a 200-meter-level surrounding rock construction area in the Dangshun tunnel, and in addition to the construction process, it will also involve the construction of the highway and the rock pile, which are great challenges.
The construction of the Xicheng railway project should not only be fast and of high quality, but also ensure production safety. In the construction of the project, we strictly implement the management concept of 'tooling to ensure technology, process quality, quality and safety', and adopt the two-lining intelligent pouring trolley in the next tunnel construction to comprehensively improve the quality of the two-lining pouring. Xia Wucai said that the engineering geology is complex, the construction is difficult, and the construction quality must be strictly controlled.
Subsequently, the reporter followed Liu Bailin to the No. 1 steel structure factory. In the huge workshop, only 10 operators and management personnel are needed, and the steel mesh sheets, small conduits, connecting plates, and steel arches are equipped with fully automated production lines for one-time molding. The information system is used for the management of steel processing and production, which realizes the whole process management of raw material processing, production planning and vehicle distribution, and the whole process of technical disclosure is electronic, and the whole process of drawing reproofing, processing, and vehicle distribution is data-based operation and management.
This steel structure factory with a high degree of informatization has laid a solid foundation for our high-quality construction of Xicheng Railway to a great extent. Liu Bailin said.
At the scene, there were also fog cannon trucks, sprinkler trucks and other vehicles and equipment parked aside. Liu Bailin told reporters that because the construction area is adjacent to the Yellow River Basin, in order to protect the ecological environment, they will consider ecological and environmental protection as an important content in the construction design. The project department adopts a closed structure in the construction of all stations and plants, and establishes sewage treatment stations, hazardous waste rooms and other workshops, and adopts gantry car washing machines, sand and gravel separators, fog cannon trucks, sprinkler trucks and other equipment to avoid large dust during the construction process. Not only that, the project department is also making every effort to do a good job in greening, fully practicing the concept of green environmental protection construction, and striving to build the project into a demonstration project for ecological protection on the Qinghai-Tibet Plateau and the Yellow River Basin.
The Chinese New Year is coming, and we will celebrate the New Year with the workers who are fighting on the front line. On the evening of the 30th day of the Chinese New Year's Eve, the project department will also prepare a sumptuous Chinese New Year's Eve dinner for brothers and sisters who stick to their posts and cannot go home to have a reunion dinner together. Liu Bailin said.
