CCTV News: New Year and new atmosphere, the struggle is right. At the beginning of the new year, a large number of new construction, new resources, new facilities and new equipment have been launched one after another. Through the construction of major projects, various regions have continuously expanded new growth points, providing strong impetus for the continued recovery and improvement of the economy.
New Year and new construction. Since the beginning of the year, many irrigation districts across the country are accelerating the construction of digital twins to accurately allocate water resources so that every drop of water can maximize its value.
The Weishan Irrigation District is the second largest irrigation area of the Yellow River and the largest irrigation area in Shandong Province. With the help of the digital twin system, scene-based dynamic simulation and rehearsal of spring irrigation, and water distribution scheduling and accurate calculation decision-making, avoiding the waste of water resources and uneven distribution caused by experience decisions in the past, ensuring that more than 5 million mu of crops drink the Yellow River water in time, and at the same time, saving nearly 30 cubic meters of water per mu, expanding the irrigation area by 100,000 mu.
The original flooding of the Yellow River water is now lifted to the underground low-pressure pipeline by the water lifting pump station. The end of the system is the farmland water-saving irrigation controller. Farmers can realize precise quantitative irrigation by swiping their card.
In Liuhe District, Nanjing, Jiangsu, the modernization renovation project of Xinyuhe Irrigation District was recently completed. The newly built digital twin platform can not only inspect and dispatch every pump station facility in the irrigation area, but also gather massive data and customize scientific irrigation plans. During the 14th Five-Year Plan period, my country allocated 200 billion yuan of central funds to modernize and transform more than 2,500 large and medium-sized irrigation areas, and 49 irrigation areas promoted digital twin pilot projects. In spring irrigation and drought resistance in 2024, the digital irrigation zones have generally improved water resource utilization efficiency by about 10%.
New Year and new resources. The newly discovered copper ore resources on the Qinghai-Tibet Plateau are more than 20 million tons. At present, the predicted copper resource potential of the Qinghai-Tibet Plateau has reached 150 million tons, and is expected to become a world-class copper resource base, significantly improving my country's copper resource guarantee capabilities.
New Year and new facilities. The Hangzhou Super Gravity Field Super Gravity Experimental Building was officially delivered for use a few days ago. The total investment of Hangzhou Super Gravity Field exceeds 2.1 billion yuan, covering an area of 89 acres. After the project is completed, it will become the world's largest capacity and strongest experimental multidisciplinary supergravity experimental facility with the largest experimental capacity and strongest experimental capabilities.
New Year's new equipment. On January 5, the "Jianghan Ping'an" double shield hard rock boring machine with the largest diameter and most complete functions among the tunnel projects under construction in my country was launched in Hubei and will be used for the construction of the Yangtze River and supplementary project. The excavation diameter of this boring machine is 11.93 meters, with a total length of about 180 meters, and a total weight of the whole machine is about 3550 tons.
Fu Haibin, chief engineer of the Civil Engineering Standard 2 of the China Railway Third Bureau's River Inlet and Buhan Project, said: "With normal operation, this double shield hard rock excavator can reach a monthly excavation progress of about 260 meters, thereby ensuring that the tunnel of this section of the road is completed by 2030."
