Since the outbreak of the epidemic, the construction of new infrastructure has provided strong support for ensuring the normal operation of people’s production and life. On March 4th, the CPC held a meeting in Standing Committee of the Political Bureau of the Communist Party of China Central Committee, proposing to speed up the construction of new infrastructure such as 5G network and data center. The investment and construction of new infrastructure such as 5G network, UHV and data center in Hebei Province also press the "fast forward button".
Recently, the reporter visited the construction sites of some new infrastructure projects in Hebei Province and saw a scene of fiery construction.

Co-construction and sharing to accelerate the realization of 5G network coverage
Recently, at the site of Shijiazhuang Unicom Botanical Garden, Wu Weijian completed the 5G coverage project of the site in half a day. "The downlink rate is 776.17 trillion per second, the uplink rate is 76.97 trillion per second, and the delay is less than 30 milliseconds, which is up to standard!" After seeing the test results on the mobile phone, Wu Weijian forgot to rest, quickly sorted out the construction site and hurried to the next Red Star Garden station to be built.
Wu Weijian is an employee of Shijiazhuang Unicom’s network department. In the past few days, he went to work at the construction site at 7: 00 a.m. every day, and then went to the construction site at 18: 00, and then went back to the unit to sort out the engineering data and make the construction plan for the next day.
"Although it’s a little harder now, it’s glorious to think that it’s to let people use the 5G network earlier!" Wu Jianwei said.
As the epidemic prevention and control continues to improve, Hebei Unicom actively organizes the resumption of work and production, speeds up and grabs progress, optimizes and adjusts the 5G construction plan, and accelerates the realization of 5G network coverage. According to the joint planning scheme of the province’s 5G base stations determined by Hebei Unicom and Hebei Telecom this year, the two sides will complete 5G network coverage in the urban areas and important counties of the province.
"The prevention and control of the epidemic situation has had a certain impact on our construction progress. Fortunately, China Unicom and China Telecom have launched a 5G network co-construction and sharing mechanism to jointly promote the deployment of 5G networks." The relevant person in charge of Hebei Unicom said that the biggest benefit of co-construction and sharing is to reduce the construction cost and accelerate the construction speed. At present, Hebei Unicom is organizing the construction of a 5G base station in Shijiazhuang, and the network coverage in the urban area will be completed in the first half of the year. The whole province will achieve 5G coverage in the urban area during the National Day.
According to reports, co-construction and sharing need to coordinate the base station site, computer room, transmission and other resources of the two operators, which increases the workload to some extent. "Since the resumption of work, Hebei Unicom and Hebei Telecom have held relevant meetings on this and increased the coordination of specific issues." According to the relevant person in charge of Hebei Unicom, at present, the two sides have completed 30% of the site survey work, and this work will be fully accelerated in the future. It is planned to complete the relevant work in the first half of the year to promote the close cooperation between the two sides.

Optimize the process to ensure the progress of UHV construction
On March 30th, in Huangshan Village, Lingyunce Township, Yixian County, Baoding City, the construction site of the 1000 kV Zhangbei-Xiong ‘an UHV AC project of State Grid Hebei Electric Power Company, from the low-altitude hoisting of 25-ton cranes to the high-altitude operation of 75-ton and 350-ton cranes, cranes with different tonnage alternately operated, and the whole tower assembly work was orderly.
"The most obvious difference between UHV and general engineering is that the tower body is large and the components are heavy. The total height of the base tower is 131.5 meters, and the tower weighs 192.1 tons. The single tower is two tons light and more than seven tons heavy. By using the crane assembly line, a foundation tower can be assembled in 13 days, which saves 5 days compared with the previous tower assembly. " Feng Li, head of Hebei power transmission and transformation site in charge of construction, said.
Zhangbei-Xiong ‘an UHV AC project is an important part of the UHV AC power grid planned and constructed by State Grid Corporation of China, and it is an UHV power transmission channel for Zhangbei new energy delivery. After the completion of the project, it will meet the load development needs of Hebei Southern Power Grid and Beijing-Tianjin-Hebei Power Grid, create conditions for xiong’an new area to achieve 100% clean power supply, and help the coordinated development of Beijing-Tianjin-Hebei. According to the plan, the project will be completed on July 20.
According to reports, because some tower numbers of the project are distributed in mountainous areas, the construction environment is complex and the weather is changeable. At the same time, due to the epidemic situation, it is more difficult to assemble towers. In order to complete the project on schedule, the construction party strictly implemented epidemic prevention and control measures on the one hand, and on the other hand, by optimizing the operation process and cooperating with each working procedure and type of work, the tower assembly and stringing were carried out simultaneously and promoted synchronously.
The overall construction of each process on the construction site brings great pressure to the on-site safety control. How to promote the project efficiently and ensure the construction safety? Feng Li innovatively applied Internet technology to develop a comprehensive monitoring system for tower assembly, which can fully understand the changes of environmental factors such as wind speed, dust and noise at the scene before the system operation desk, and can remotely monitor, command, check and confirm the release, and correct violations in real time, thus realizing the safety and efficiency of power grid construction.
"I am very proud to participate in the project construction and contribute to the construction of xiong’an new area. We must do a good job in on-site control, optimize the operation process, and ensure the safe, high-quality and efficient completion of the project. " Feng Li is full of confidence.
Go all out to ensure the safe and stable operation of the data center
Frequent shuttle between the computer room and the construction site, working nearly 15 hours a day on average … This is the working state of Fu Xulun and his colleagues in the past two months. During the epidemic prevention and control period, as the person in charge of the data center of China Mobile (Baoding, Hebei), Fu Xulun was under great pressure to ensure the normal operation of the data center in the case of shortage of manpower and materials.
China Mobile (Baoding, Hebei) data center was put into operation in October 2017, which is an important part of the strategic layout of China Mobile’s national data center. At present, the data center has settled in Baidu, Ali and other Internet companies.
Affected by the epidemic, schools in Hebei Province have implemented online classes, many enterprises have telecommuted, online shopping has also increased, and the workload of data centers has surged.
In February, in order to meet the online education needs of primary and secondary school students, Hebei Mobile urgently expanded the "cloud video" system. In the case of shortage of facilities and personnel, Fu Xulun and his colleagues mobilized all materials and mobilized all forces to overcome difficulties. They worked continuously for three days and nights, and finally completed the hardware installation and software integration of the "cloud video" system to ensure the smooth online of the system. According to the normal construction progress, it will take at least half a month to complete this work.
Internet companies such as Baidu and Ali, which have settled in data centers, are facing a huge impact on the bandwidth of Internet companies due to the increase in online cloud classrooms and other applications, and the network traffic has increased significantly. In order to ensure the smooth flow of the network, Fu Xulun and his colleagues worked out an emergency plan, and completed the docking of the bandwidth access plan, hardware construction, software debugging and other work of Internet companies in just one day, which met nearly 20% of the traffic demand of Internet companies and ensured the various network application needs of netizens at home.
In the past few days, it has been normal for employees in the data center to call it a day at 10 pm. Fu Xulun said that the construction and operation of the data center involves all aspects of work and has a large workload. During the epidemic prevention and control period, they need to go all out to ensure the safe operation of the data center.
"The work is a little busy, but the inner feelings are more full of sense of accomplishment." Fu Xulun said that new infrastructure is being strongly supported from the national level to the local level. In the future, video communication and driverless driving will all show explosive growth, and people’s lives and work will also usher in great changes. They have also increased their investment in the overall supply of data centers. At present, they are stepping up the construction of the 5G core network, which will be officially put into use in mid-April according to the established plan. Seeing that the project is drawing to a close, they think that they can contribute to the national communication construction. Their hearts are warm and happy.
It is understood that Hebei Mobile actively promotes business transformation, continuously improves the construction of communication information infrastructure, and actively deploys in the fields of mobile Internet, cloud computing, big data and Internet of Things. At present, Baoding Data Center, Langfang Data Center and Shijiazhuang Data Center have been built to effectively support the development of Internet data centers, cloud computing and other businesses. This year, the external power expansion of Baoding data center, Langfang data center and Shijiazhuang data center and the supporting renovation project of computer room will be carried out as needed. At the same time, promote the land acquisition and construction of Zhangjiakou data center. (Reporter Fang Suju)
