Strengthening brand building is the internal 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 big country heavy weapons, such as the "Dream" model of the super diameter shaft boring machine, the intelligent robot used for cutter head welding, and the "Deep Sea No.1" energy station model, shine brightly, demonstrating the "hard core" strength of Chinese brands.

Underground space is a new space carrier for urban development. At the site of China Brand Expo, the supporting activity of China Brand Day, the reporter saw that the "Dream" model of the super diameter shaft boring machine brought by China Railway Construction 15th Bureau attracted attention from all parties. The whole machine of "Dream" is 10 meters high and the excavation diameter reaches 23.02 meters. The equipment integrates excavation, slag removal, support, guidance and other functions. For underwater construction, the maximum excavation depth can reach 80m.

Chen Zixuan, an exhibitor of China Railway Construction 15th Bureau Group, said that the vertical three-dimensional underground parking garage built by "Dream" is a modern smart garage integrating intelligent equipment, operation, monitoring, maintenance and management. 304 parking spaces only need one touch of mobile phones, and the average parking time is only 90 seconds.

If you want to do a good job, you must first sharpen your tools. Cutterhead welding is an important link in the assembly of shield machines, which are powerful tools for underground tunnel construction. At the China Brand Expo, the intelligent robot for cutter head welding displayed by China Railway 14th Bureau was particularly eye-catching. Ma Zekun, engineer of the Technical Center of China Railway 14th Bureau Large Shield Machine Co., Ltd., introduced that the cutter head welding robot has optimized the efficiency and quality of cutter head welding, which can reduce manpower by about 40% and improve construction efficiency by about 50%. At present, it has been applied in projects such as Beijing Binhai Intercity Railway and Suzhou Jiaxing Ningbo High speed Railway.

CNOOC, which debuted on China Brand Day for the first time, also brought a series of major powers' heavy weapons. 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 3D and other display methods, let the visitors to clock in deeply understand the cutting-edge scientific and technological achievements of the whole chain of marine energy.

It is reported that the "Deepwater No.1" atmospheric field is the deepest and most difficult to explore and develop offshore ultra deepwater gas field independently discovered in China so far. Its production marks that China's offshore oil exploration and development capacity has achieved a historic leap from 300 meters to 1500 meters of ultra deepwater.

In addition, CNNC Group has brought the "Hualong No.1" nuclear power technology demonstration model with full independent intellectual property rights, China Southern Power Grid has brought the first independent and controllable large power model "Dawat" in the power industry, and China Aviation Industry has shown the large amphibious aircraft "Kunlong" AG600M... The heavy equipment of major countries shown at the brand day activities covers energy, transportation Urban construction and other aspects fully demonstrate the "hard core" strength of Chinese brands.
