Strengthening brand building is an inherent requirement for developing new quality productivity and promoting high-quality development. At the 2024 China Brand Day event being held in Shanghai, a series of national heavy weapons such as the "Dream" model of the ultra large diameter shaft boring machine, the intelligent robot used for cutterhead welding, and the "Deep Sea No.1" energy station model shone brightly, showcasing the "hard core" strength of Chinese brands. Underground space is a new spatial carrier for urban development. At the China Brand Day supporting event, the China Brand Expo, the reporter saw that the "Dream" model of the ultra large diameter vertical shaft boring machine brought by China Railway Construction 15th Bureau has attracted attention from all parties. The Dreamliner is 10 meters high and has an excavation diameter of 23.02 meters. The equipment integrates functions such as excavation, slag removal, support, and guidance. During underwater construction, the maximum excavation depth can reach 80 meters. Chen Zixuan, an exhibitor of China Railway 15th Bureau Group under China Railway Construction Corporation, introduced that the vertical and three-dimensional underground parking garage built by "Dream" is a modern smart garage that integrates equipment, operation, monitoring, maintenance, and management intelligence. With 304 parking spaces accessible with just one click of a mobile phone, the average parking and pick-up time is only 90 seconds. To do a good job, one must first sharpen their tools. The welding of the cutterhead is an important part of the assembly of shield tunneling machines, which is a powerful tool for underground tunnel construction. At the China Brand Expo, the intelligent robot used for cutterhead welding displayed by China Railway 14th Bureau was particularly eye-catching. Ma Zekun, an engineer at the Technical Center of China Railway 14th Bureau Shield Company, introduced that the cutterhead welding robot has optimized the efficiency and quality of cutterhead welding, reducing labor by about 40% and improving construction efficiency by about 50%. It has been applied in projects such as the Beijing Binhai Intercity Railway and the Tongsu Jiayong High speed Railway. China National Offshore Oil Corporation (CNOOC), which made its debut on Chinese Brand Day, has also brought a series of major national treasures. Exhibits such as the "Deep Sea No.1" energy station model, the "Green Energy Port" sand table, and the "Xuanji" system physical model, combined with naked eye 3D display methods, allow visitors who come to check in to have a deep understanding of the cutting-edge technological achievements in the entire ocean energy chain. It is reported that the "Deep Sea No.1" atmospheric field is the deepest and most difficult to explore and develop offshore ultra deep water gas field independently discovered in China so far. Its production marks a historic leap in China's offshore oil exploration and development capacity from 300 meters deep to 1500 meters deep. In addition, China National Nuclear Corporation (CNNC) has brought the fully independent intellectual property rights of the "Hualong No.1" nuclear power technology demonstration model, China Southern Power Grid has brought the first independently controllable power model in the power industry, the "Big Watt", and China Aviation Industry has shown the large amphibious aircraft "Kunlong" AG600M... The brand day event showcased the "hard core" strength of Chinese brands in various aspects such as energy, transportation, and urban construction. (Lai Xin She)
