Xinhua News Agency, Beijing, November 30th. Title: Why are Huoshenshan and Leishenshan hospitals built so quickly?
The technology code is here!

The Significant Technological Achievement Exhibition of the China Construction Technology Innovation Conference that is being held in Beijing has attracted widespread attention. Some of the technologies related to the construction of Vulcan Mountain and Leishen Mountain Hospital attract visitors.
In more than 10 days, a hospital has risen from the ground. What hard-core technology "codes" are behind the "Chinese speed" that has amazed the world?
Do you still remember the scene where hundreds of millions of netizens were cheering for the construction of two hospitals 24 hours a day by "cloud supervisors"?
On the construction site, one by one box-style houses are installed extremely quickly, which is the primary "nirvana"-a new technology of highly modular assembly construction.
"Long-term technology accumulation, innovation while doing work, integration and re-innovation, and continuous industrialization are the cornerstones of miracles." The relevant person in charge of China State Construction Group said in an interview with Xinhua News Agency reporters. Power of science and technology.
If the image of prefabricated construction technology is described as "building a house with building blocks", the box-type board house processed and prefabricated by the factory is "building blocks."
As the main building of Huoshenshan and Leishenshan hospitals, box-style house installation is the core part of hospital construction.
What a spectacular scene: the assembly horn sounded, more than 2,500 large-scale equipment and transportation vehicles, more than 4,900 box-type board houses, 200,000 square meters of anti-seepage membrane and other large quantities of materials were quickly assembled in a few days.
Huoshenshan Hospital has a building area of 34,000 square meters, and Leishenshan Hospital has a building area of 79,900 square meters. With such a huge scale, how can the assembly and modification of various box-style rooms achieve seamless docking?
Under extreme conditions, digital construction shows its talents.
"Simultaneous operations of land, sea and air forces in the information age" is an image expression of the multi-dimensional and three-dimensional all-professional interspersed operations at that time.
"Information and data interaction is the key, digital simulation is not in place, and on-site splicing is a mess." The person in charge said that coordinated operations use a large number of cutting-edge technologies such as building information modeling (BIM) and smart construction.
On the self-developed BIM platform, 360,000 meters of various pipelines and more than 6,000 information points can be computer-simulated in advance to generate three-dimensional digital simulation models, data and numbers, and then real-time correction according to the site conditions.
Hundreds of subcontractors, thousands of processes, and more than 40,000 builders use the data generated by these computers to seamlessly connect and advance simultaneously.
Modular design, fishbone-like layout, strict distinction between doctors and patients, and air pressure control wards to prevent proliferation...To achieve the goal of "zero diffusion" and "zero infection" in the whole process of construction, operation and maintenance, the construction precision of infectious disease hospitals is extremely high. Sewage treatment stations and garbage incineration tanks need to be built to realize the closed treatment of all toxic gases, polluted water sources, and medical waste.
For example, in order to prevent rainwater that may contain viruses from infiltrating underground, the ground of the hospital isolation area is equipped with three protections: concrete base, impermeable membrane and reinforced concrete ground layer to ensure that all rainwater enters the storage tank in the hospital and is discharged into the city after disinfection Sewage system.
The construction of Huoshenshan and Leishenshan hospitals embodies the pace of technological development and innovation of "built in China".
Using 5G, AI, cloud computing, big data and other modern information technologies to develop an intelligent operation and maintenance management platform, linking 17 information systems in 5 categories of hospitals, forming a "smart brain", realizing smart security, smart logistics, and smart review , "Zero touch" operation and maintenance.
The person in charge said that the extreme scenario is a "big test" of my country's construction industrialization technology, which has not only withstood challenges, but also exposed "pain points" and "shortcomings."
By opening up the industrial chain, laying out the innovation chain, and tempering Chinese standards, the construction of Huoshenshan and Leishenshan hospitals will give rich enlightenment to the future development of China's construction industry technology.
