In response to the call of the state and the new needs of national urban architecture and environmental construction in the digital age, Professor Xu Weiguo, Institute of Future Habitat, Shenzhen International Graduate School, Tsinghua University, jointly with the School of Architecture, Tsinghua University, has carried out independent research and development and innovation of an interdisciplinary team. To turn 3D printing concrete technology into an interdisciplinary integrated intelligent construction industry technology, Shenzhen Baoan 3D Printing Park, located in front of Hall 17 of Baoan Convention and Exhibition Center, is a vivid practice of its industrial application. It is reported that "printing" a city square is the first practical application of the new technology of 3D printing concrete in the global municipal engineering construction.
With the comprehensive development of material science, software development, equipment automation and other interdisciplinary fields, 3D printing concrete has become an important technical means to lead the construction industry towards intellectualization. In July 2020, the Ministry of Housing and Urban-Rural Development and other 13 departments jointly issued the Guiding Opinions on Promoting the Coordinated Development of Intelligent Construction and Building Industrialization, which clearly pointed out that we should vigorously develop building industrialization as the carrier, take digital and intelligent upgrading as the driving force, increase the application of intelligent construction in all aspects of engineering construction, and promote it. To form an intelligent construction industry system covering scientific research, design, production and processing, construction and assembly, operation and other industrial chains.
u Valley: Creating Free and Smart Urban Green Space
with 3D Technology Shenzhen Baoan 3D Printing Park is located in front of Hall 17 of Baoan Convention and Exhibition Center, with a land area of 5523. Shenzhen Baoan 3D Printing Park realized the world's largest 3D printing city park construction attempt for the first time in September 2021. The design concept of the
park is "clear flow in the valley". The winding road curve and the natural undulating terrain are integrated to simulate the form of clear spring flowing in the valley. The vivid and flexible garden sketches are perfectly combined with the horizontal extension of the terrain to create a unique natural space.

In the overall planning and design of the park, Professor Xu Weiguo's team first used the particle swarm optimization algorithm of GH plug-in QUELEA to predict the future crowd activity status of the site through human flow simulation; In the simulation calculation, the three entrances and exits in the site and one landscape viewing point in the north and south of the site are taken as the elements affecting the movement of the crowd, so as to obtain the winding and complex trajectory of the crowd on the site. On this basis, other potential crowd gathering areas and paths of crowd activities are obtained through the method of people flow heat analysis. Flow path map

of 3D Printing Path in Shenzhen Designed by Professor Xu Weiguo's Team In Baoan 3D Printing Park, the research team has made innovative explorations on the printing path planning forms of many landscape sketches, such as variable surface printing and interlayer printing technology. Through technological innovation, the research team has made it possible for the 3D printing concrete construction of the mechanical arm to achieve new possibilities in the printing path planning. The "Pengcheng Blossom" sculpture and the "Baoan" sculpture in the park are representative innovative works.

Subverting Tradition: Tsinghua SIGS Team Contributes
to National Intelligent Construction With the increasing demand for the volume and construction of 3D printing buildings in the country, Printing path collaboration, real-time speed control, intelligent printing path generation and other fields of multiple robotic arms are all topics that are being explored and constantly broken through in the 3D printing concrete industry.
< IMG SRC = "https://img7.ccement.com/richtext/img/wu1wndxts0a1675317696589. the robot 3D printing construction technology independently developed by Professor Xu Weiguo's team at the Shenzhen International Graduate School of Tsinghua University, It is an intelligent construction method based on automatic control technology, which has the advantages of saving manpower, improving efficiency, reducing cost, environmental protection and ecology, and ensuring quality. It can not only build traditional architectural forms, but also build a variety of rich organic architectural forms, which conforms to the ecological theme of green environmental protection in the world today, and can bring a new look to our living environment and intelligent construction industry.
