The Wuhan production base of AVIC Lithium Battery of China Construction Second Engineering Bureau is located in Hannan District, Wuhan. The first bid section of this project has a total construction area of 146,000 square meters and a planned production capacity of 20GWh. As the production and sales base of power batteries and energy storage batteries, it will drive the upstream and downstream industrial chain enterprises to settle down. The products mainly support domestic and foreign application fields such as new energy vehicles and energy storage markets, and it is expected to be completed and put into operation next year.

'The volume of the project is huge, with a single floor area of 47,000 square meters. According to the area of 600 square meters per building, it is equivalent to 80 commercial buildings starting at the same time. The required weight of fastening materials alone is as high as 16,000 tons and the volume is 1.1 million cubic meters.' Liang Zhengyu, chief engineer of the project, introduced that all the projects are ultra-high and over-limit formwork projects and support systems, which have extremely high construction risks. In order to ensure the construction speed and safety, the project has selected 60 series of heavy-duty buckle systems, with adjustable supporting bearing capacity of 140KN, which can be used for rapid construction on the premise of ensuring the construction safety.

Since entering the site in December 2021, the project has started the 'racing' mode. Nearly1,000 workers and dozens of tower cranes, from day to night, from traffic to silence, the construction site is always a hot scene. According to the site conditions, the project team held several special meetings to prepare winter construction materials and overcome many unfavorable factors, such as strict epidemic control, rainy and cold weather, difficult horizontal transportation and so on. Nearly a thousand people participated in the comprehensive tiling operation, and completed the casting of 47,000 square meters of floor slab, about 30,000 cubic meters of concrete and the erection of 200,000 cubic meters of ultra-high and over-limit formwork support system in 25 days. The foundation construction was completed 8 days ahead of schedule, and the roof capping stage was entered 20 days ahead of schedule. The project team made progress again and again, and became more and more brave.

After careful planning and organization, the project team reduced the main capping time agreed in the contract by 20% through the labor input of more than 1,400 people per day, and completed the full capping ahead of schedule on March 5th. This is the 89th day of the sprint of the project team, and the first day that the first new energy automobile battery factory in Wuhan has entered a new stage. After the completion of the project, it will fully promote the extension of Wuhan's new energy industry chain, enterprise agglomeration, scale improvement and demonstration application, and make significant contributions to the building of new energy industry clusters and the high-quality development of regional economy in Wuhan.
