by The “new height” of infrastructure construction under high temperature – the green precast substation makes the park more “call” at 30 ℃, 31 ℃ and 33 ℃…
Since the dog days, the high temperature has swept Lucheng, and the daily maximum temperature is above 33 ℃.
“Today’s task is to lay corrugated steel plates.
Please prepare personal tools and bring enough heatstroke prevention and cooling supplies…” in order to avoid high temperature periods, the construction operation is “early rather than late”.
At the construction site of Fuxing 110kV power transmission and transformation project at 6 a.m., more than 30 construction personnel have been ready for work.
At about 9 a.m., the sun was scorching.
Under the scorching sun, the clothes of operators wearing thick work clothes, safety helmets and thread gloves and hanging various tools have long been soaked with sweat.
“Work clothes and safety helmets are standard for our work.
It’s difficult to wear long sleeved work clothes in hot weather.
Wearing safety helmets is more like a small stove on top of our head, but in order to be safe, we must dress properly.” The construction personnel said while wiping sweat.
It is reported that the steel structure assembly of Fuxing 110kV substation began on June 1.
After more than a month of intense work, the laying of the last roof corrugated steel plate was completed on July 8, the roof concrete pouring was completed on July 11, and the main control building was officially capped.
“First, the underground part shall be poured, and then the building components shall be spliced in according to the reserved position, which is similar to large-sized assembled building blocks.” Project Manager Li Mengchen took the author to the steel beam.
These steel beams are about 6 meters long and half a meter wide.
It takes 5-6 people to cooperate with the crane to fix them.
Li Mengchen said, “this is the first main cast steel structure substation in Baotou.
The construction period is 30% shorter than that of the traditional substation, and the firmness and seismic capacity of the house are better.
At the same time, the assembly operation does not need sand and gravel, and almost all of them are dust-free operations, which can minimize the” Four Wastes Pollution “generated in the process of substation construction, The average amount of construction waste and dust is reduced by 78%, the power consumption is saved by more than 20%, and the water consumption is saved by 50%.
” With the progress and development of science and technology, standardization, simplification and precast modularization have become the new goals of substation construction.
Fuxing substation is designed and constructed according to the positioning requirements of the group company’s responsible power supply, green power supply and digital power supply.
It has the characteristics of high strength, light weight, low cost, green environmental protection and so on.
“In view of the characteristics and difficulties of the project, such as large span and wide high-altitude operation, construction simulation, ground pre assembly and other methods are adopted, and the construction progress is intelligently controlled through advanced technical means such as visualization, informatization and mobile Internet.
Key links such as operation dynamics on the construction site, foundation pit excavation and scaffold erection are tracked in real time to ensure the construction quality of key nodes.” Li Mengchen introduced.
At present, the station has entered the electrical installation stage and is installing two 63 megavolt a main transformers.
It is the first all steel structure indoor intelligent substation of Baotou Power Supply Bureau.
The project investment is 68.63 million yuan.
It is expected to start power transmission before October 30.
After completion, it will provide 110 kV power supply points for Baotou metal deep processing park, meet the load needs of important users such as Meike silicon phase I and II projects in the park and Baotou Steel Rare Earth downstream enterprises, further improve the economy and reliability of regional power grid operation, and play an important role in optimizing the power grid structure and economic development in the west of Baotou city.
