On the morning of the 26th, the participating experts first visited Yingchuang Shanghai 3D Printing Circulation Industrial Park, Suzhou Ring Express 3D Printing Sound Barrier, and Yingchuang Suzhou 3D Printing Expo Park.

On the afternoon of the 26th, expert representatives jointly discussed the road in the context of the country’s “formation of a new development pattern in which domestic and international double cycles are the mainstay and mutual promotion of domestic and international double cycles”, “innovative infrastructure”, “ecological civilization” and “green transportation”. , How to use 3D printing construction technology to upgrade railway sound barriers, which is more economical, more noise-reducing, and more environmentally friendly; discuss the application scenarios of 3D printing construction technology in transportation infrastructure construction and key technical directions that need to be developed; share Yingchuang 3D Printing construction technology is a cooperative model that facilitates the transformation and upgrading of traditional industries and empowers traditional industries.

The seminar was presided over by Shao Shegang, Vice Chairman of the Professional Committee for Green Development of Transportation of China Transportation Association.

Yingchuang Construction Technology (Shanghai) Co., Ltd. Ma Yihe introduced the exploration, development and successful application of Yingchuang's 3D printing construction technology in highways and other transportation facilities.

Song Shaohua, deputy general manager of Suzhou Ring Expressway Co., Ltd., compared traditional acoustic barriers such as acrylic, and clarified the advantages of Yingchuang 3D printed noise barriers in terms of cost, construction, installation, safety, and noise reduction.

Yan Xiang, director of the Building Acoustics Laboratory of Tsinghua University and deputy director of the Building Environment Testing Center of Tsinghua University, explained the sound elimination of 3D printed sound barriers and the results of acoustic experiments on 3D printed sound barriers from an acoustic perspective. Yingchuang 3D printed sound barriers are practical The noise reduction is 20-30 decibels, which is 3-5 times the noise reduction effect of traditional sound barriers. It points out that the 3D printed wave-shaped sound barrier also achieves the psychological noise reduction effect due to its beautiful appearance.

Yu Wensheng, deputy general manager of Jiangxi Expressway Investment Group Co., Ltd., pointed out that because of its design and cost advantages, 3D printing construction technology has more space for transportation construction and can be widely used in the construction of characteristic open service areas and highway intersections. Emergency buildings, etc.

Xie Hongbo, deputy general manager of the Second Industrial Investment Management Department of Zhejiang Transportation Investment Group Co., Ltd., proposed that Yingchuang's 3D printing construction technology is close to the "new development concept"-innovation, coordination, green, open, and shared, and from cost and technology maturity , Safety performance and other aspects.

Zhang Bin, director of the Beijing Labor Protection Science Research Institute, combined his experience in the Netherlands and pointed out that the sound barrier printed by Yingchuang for the expressway around the city is a sound barrier with ecological, landscape and sound insulation performance, and it is a good one. The prototype of the acoustic landscape is cultural, distinctive, and innovative, and hopes to promote industrialization and move towards users.

Li Weimin, deputy chief engineer of Guangdong Provincial Communications Group Co., Ltd., pointed out the application prospects of 3D printing buildings in the southern urban landscape bridge from the aspects of intelligent concrete pouring technology and special-shaped buildings.

Zheng Bin, chief engineer office of Shanghai Chengtou Highway Investment (Group) Co., Ltd., started from the construction of Shanghai urban roads and river treatment, and proposed that the installation method of 3D printing buildings should meet the construction efficiency and environmental protection requirements of Shanghai and other metropolises.

Li Guofeng, deputy chief engineer of Yunnan Provincial Transportation Investment and Construction Group Co., Ltd., extended the application field of 3D printing construction. He believed that blank spots in the market should be developed and high-speed landscape applications should be developed not only for cities, highway sculptures, and sketches, but also for transportation facilities. The façade of the city, the piers of urban bridges, the cultural paintings of stone slopes, etc.

Xing Yi from the Transportation Management Center of Shanghai Chengtou Highway Investment (Group) Co., Ltd. proposed that Yingchuang could optimize technology, installation and design in terms of durability, economy and noise reduction, and save costs.

Guo Shaoying, deputy chief engineer of China Railway Fifth Survey, Design and Research Institute Co., Ltd., made suggestions from three aspects: materials, equipment, and acceptance.

Deng Da, the chief engineer of the Bridge Office of the Survey and Design Division of China Highway Engineering Consulting Group Co., Ltd., suggested that Yingchuang start with 3D printing building technical standards, quality standards and process standards to open up market recognition.

Qu Bo, deputy general manager of Jingheng Company of Guizhou Construction Investment Group, and Zhang Zhaoxun, deputy director of the Chief Engineering Office, are concerned about the cost and acceptance of 3D printed buildings.

Li Yongzhong, a partner of the Green Industry Fund, focuses on international recommendations for Yingchuang's 3D printing construction technology to form international standards, share standards, and promote the improvement of the entire 3D printing industry.

National senior interior architect Xie Jiandong pointed out that the design of 3D printing building technology has more local characteristics, giving way to culture and art, and the road has a soul.

After discussions with experts in the fields of production, learning, research, and application, the meeting improved the 3D printing sound barrier technology, and clarified the application scenarios, technology research and development directions, and promotion and application model innovations of 3D printing construction technology in the construction of transportation infrastructure. It is a 3D printing building The application of technology in the construction of transportation infrastructure points out the direction and will help the transformation and upgrading of transportation infrastructure construction technology.
