Accelerating the Promotion of a Series of Major Engineering Projects to Assist China's High Quality Economic and Social Development
Recently, a series of major engineering projects in China have accelerated, helping to promote high-quality economic and social development.
The largest span sea crossing bridge in China has officially entered the construction phase of offshore main towers
On November 19th, the construction of the offshore pier foundation of Shuangyumen Bridge in Ningbo, Zhejiang Province was completed, marking the official entry of the largest span sea crossing bridge in China into the offshore main tower construction phase. The Shuangyumen Bridge has a main span of 1768 meters and is expected to be completed and opened to traffic in 2027, which will effectively improve the external transportation conditions of the southern wing islands of Zhoushan.
Jiangsu: Assembly construction of 50% of newly started key transportation engineering projects
In the first three quarters of this year, Jiangsu Province completed a cumulative investment of 2013.4 billion yuan in the construction of public, rail, water, and air infrastructure, completing the annual investment plan one quarter ahead of schedule. At present, the proportion of prefabricated construction of newly started key transportation engineering projects in Jiangsu has reached 50%. At the construction site of the Fengxiang Expressway North Extension Project in Wuxi, a prefabricated box girder weighing 101 tons and measuring 30 meters in length was successfully assembled like building blocks. These box girders come from an assembly workshop 20 kilometers away. Concrete mixing, steel reinforcement processing, pouring and forming, and other 10 processes, achieving assembly line operation.
Dong Yunchao, the construction manager of the Fengxiang Expressway North Extension Project in Wuxi, Jiangsu: Factory prefabrication, on-site assembly, the entire process is like building blocks, with an assembly rate of over 80%, which can be completed in one year, reducing the construction period by half.
Wu Feng, Deputy General Manager of China Railway Construction (Wuxi) Engineering Technology Development Co., Ltd.: The first is the digital integration of production, and the second is the overall coordination of design, construction, and production. The orders we are currently working on are already in April 2026.
Rushan, Shandong: 450000 kW offshore wind power grid connected to the southern peninsula for power generation
Recently, the first phase of the Shandong Peninsula Nanhai Wind Power U1 Site Project, with a full capacity of 450000 kilowatts, was connected to the power grid for operation. To ensure the smooth progress of grid connection, State Grid Weihai Power Supply Company has carried out power load transfer for 14 power outage lines, erected 52 iron towers, and lasted for 5 months without power outage. This not only ensures the normal electricity consumption of residents, but also provides convenience for offshore wind power line crossing and sealing operations.
The project is located in the sea area south of Rushan in Weihai, Shandong, with a total installed capacity of 450000 kilowatts. At present, the 53 units in the first phase of the project are operating normally, and all green electricity has been connected to the grid for operation.
Zhu Kunyang, Deputy Director of the Engineering Construction Department of Shandong Ocean Energy Development Co., Ltd. of State Power Investment Corporation, said that under an average annual wind speed of 7.16 meters per second, the annual power generation of a single wind turbine can reach 25.47 million kilowatt hours.
