During the National Day holiday, power builders across the country stuck to their posts, seized the construction period to erect towers and wires, and accelerated the construction of key power grid projects.
In Tianquan County, Sichuan Province, on Erlang Mountain, which is 3,058 meters above sea level, the temperature has dropped below 10 degrees Celsius, but it is busy at the construction site of the 1,000 kV UHV AC transmission project in Sichuan and Chongqing. On the nearly 100-meter-high iron tower, the construction personnel are firmly fixing the newly unfolded wires with the tower through the crimping tube. During the National Day, more than 600 workers here stuck to the front line to carry out the work of wire tightening and accessory installation in the portal tower section.
Yu Dong, Chief Engineer of State Grid Sichuan Electric Power Sichuan-Chongqing UHV Sichuan 9 Bid Section: At present, the Sichuan-Chongqing UHV project has entered the construction sprint stage, and more than 10,000 builders are fighting on the site. After the project is put into operation, it can transmit more than 35 billion kilowatt hours of electricity per year, which can greatly improve the power supply capacity of Sichuan and Chongqing.
In Hunan, Ningdian's UHV project in Hunan has also entered the peak period of the tower line. At the construction site of the project, with the help of the visual stretching system, the power workers successively erected 12 wires with a diameter of 42.9 cm to the iron tower, connecting an "electric flyover" in the air.
Zou Tonghua, Chief Engineer of Hunan Power Transmission and Transformation Engineering Co., Ltd.: During the festival, we invested a total of 23 tower teams, 21 sets of landing double rocker arm poles, and 12 cranes of various types to accelerate the tower assembly and line work through mechanized construction. At present, our bid section of the project has completed the formation of 208 towers, and the whole project is expected to be completed before the Spring Festival this year.
In addition, in Suzhou City, Anhui Province, the second phase of the Qianyingzi Power Plant 500 thousand volt transmission project site, nearly 200 construction personnel to set up transmission towers, erect wires, the project will be completed and put into operation by the end of October this year. After it is put into operation, it can provide 800 MW of peak shaving capacity for new energy consumption, adding a new guarantee for stable and reliable power supply in East China.
In Suzhou, Jiangsu Province, during the National Day, nearly 100 power construction workers are carrying out relocation and renovation operations on a power tower along the North Yangtze River Railway. The North Yangtze River high-speed railway is an important part of the mainland's "eight vertical and eight horizontal" high-speed railway network, due to the two 500 thousand volt transmission lines across the railway channel, the safety distance can not meet the requirements of railway construction, in order to "make way" for the construction of the North Yangtze River high-speed railway, the local power supply department took advantage of the National Day electricity load trough period, seized the construction period, and stepped up the demolition of the old tower and the old line, the construction of the new tower and other construction operations.
The festival is not stopped, and the construction period is in full swing
During the National Day holiday, there are still many builders who stick to their posts, grasp the progress, rush the construction period, and ensure the orderly progress of the project.
This holiday, the Wuhuang Expressway reconstruction and expansion project is still a busy scene, with more than 350 workers working on backfill earthwork and steel bar welding. Since the opening of the Wuhan-Huangshi Expressway, the average daily traffic volume has been rising, reaching several times the design capacity during peak periods. After the completion of the reconstruction and expansion, the road will be changed from two-way four-lane to two-way eight-lane, which will greatly alleviate the traffic pressure.
At the construction project site of the College of Pharmacy and Nursing of Hubei University of Medicine in Shiyan, Hubei Province, construction vehicles shuttled back and forth, and workers were busy welding steel bars and pouring concrete. This holiday, more than 1,800 builders at the construction site stuck to their posts and made every effort to promote the progress of the project.
Ding Yi, the person in charge of the construction project: More than 1,000 workers are fighting day and night, grabbing sunny days and cloudy days, all kinds of construction machinery are at full power, and they will not stop working during the National Day holiday to ensure that the task is completed on schedule.
During the National Day, the construction of the Qianping Reservoir Irrigation Area Project in Henan Province continued to advance, and workers were busy with steel pipe installation and concrete construction. The Qianping Reservoir Irrigation Area Project includes the North Trunk Pipe, the South Trunk Canal and its subordinate canal system projects, which can effectively guarantee the safe drinking water of 1.2 million people along the route and the irrigation water of more than 500,000 mu of cultivated land after completion.
Liu Xiaosui, deputy general manager of Henan Qianping Reservoir Irrigation District Engineering Co., Ltd.: During the National Day, we took a non-stop shutdown, reasonably arranged personnel to take rest and shifts, seized the golden period of construction, and laid a solid foundation for the completion of the annual goals and tasks.
