The world’s longest span precast concrete 3D printing bridge was completed in Hebei University of Technology
The overall shape design of the bridge railing caters to the hole curve of Zhaozhou Bridge.
The design scheme is more flexible.
At the ceremony of the completion of Zhaozhou Bridge with precast concrete 3D printing, Professor Ma Guowei, Vice President of Hebei University of Technology and Dean of the School of Civil Engineering and Transportation, introduced the relevant situation of the precast concrete 3D printing of Zhaozhou Bridge to foreign and Chinese guests Infrastructure and other fields have risen rapidly and shown great development potential.
On the afternoon of October 13, Professor Ma Guowei, Vice President and Dean of the School of Civil Engineering and Transportation, led his research team to complete the cast 3D printing of Zhaozhou Bridge in Beichen Campus.
At the ribbon cutting ceremony for the completion of Zhaozhou Bridge with precast concrete 3D printing, Ma Guowei said that 3D printing, as a new technology, is a new construction mode that subverts the tradition.
3D printing can save about 1/3 of the building materials and 2/3 of the labor force, and highly automated printing process can greatly improve the construction efficiency.
Li of the University of Michigan, Li Jiulin, the chief engineer of Beijing Urban Construction Group, Professor Jay Sanjayan of Australia’s Swinburn University of Science and Technology, and Wang Changke, the general manager of Northern Design and Engineering Research Institute, all made speeches to congratulate the completion of the Zhaozhou Bridge with cast 3D printing, and expressed their views on promoting the rapid development of key technologies of intelligent construction It is of epoch-making significance to realize the greening, industrialization and intellectualization of China’s buildings.
At the same time, it can also be used in the protection of ancient buildings to accurately restore the damaged and lost parts of ancient buildings.
The development of intelligent construction with 3D printing technology as the core can promote the development of the construction industry in the direction of green, industrialization and intelligence, and help the national construction industrialization process.
The peach blossom element is added to the bridge deck and the railing, which means that the world is full of peaches and plums.
It can use the special texture in printing to give special skin to buildings.
3D printing is a rapid construction process without formwork.
Professor Han Xu, Deputy Secretary of the Party Committee and President of the University, and more than 150 scholars from 10 countries and regions attended the inauguration ceremony.
The cast concrete 3D printing Zhaozhou Bridge draws on the construction experience of the built 3D printing buildings, introduces BIM virtual simulation technology and modern intelligent monitoring means, uses modular printing technology to optimize the design of node assembly forms, directly carries out cast construction on site, endows the traditional bridge with modern flavor, and fully realizes the design of new type, material functionality, construction virtualization, assembly modularization and monitoring intelligence, It is an important step for our school to successfully apply the concept of green intelligent construction to the road of production, teaching and research.
It can freely and flexibly build special-shaped concrete structures and buildings without formwork support.
Compared with the traditional construction of the cast concrete Zhaozhou Bridge, which stands in the Beichen Campus of Hebei University of Technology, 3D printing is an innovative technology to promote the development of precast buildings and intelligent construction.
Professor Behrokh Khoshnevis of the University of Southern California, Han Zhenyong, the chief engineer of Tianjin Urban Construction Group, Professor Victor C.
Welcome to like and forward.
At the same time, the railing is embedded with words from 1903, 1912, 1929, 1952, 1995, 2019 and other years, which means the development of the school in 116 years.
The technology can greatly improve the construction efficiency and does not increase the cost due to the geometric complexity of the structure; It can greatly reduce the pollution to the on-site environment and is an innovative technology to promote the development of precast buildings and intelligent construction; In the process of 3D printing the bridge, many sensors are embedded to monitor the health of the bridge 24 hours a day, so that problems such as stress can be found and eliminated in time, ensuring safety first and also reflecting intelligent integration.
