Zhengding Container House Construction

The construction of container houses in Zhengding mainly adopts a prefabricated light steel structure system, characterized by rapid construction, standardized production, and recyclability.

I. Construction Process and Characteristics

1. Foundation Construction: The construction site must first undergo land leveling and ground hardening to provide a stable foundation for the rapid assembly of container houses. For example, in the construction of the centralized quarantine site in Zhengding County, Shijiazhuang, hundreds of construction machinery operated day and night, completing the surface clearing and hardening of a 500-acre site in just one day.
2. Modular Installation: Container houses are prefabricated in factories and assembled on-site. The main structure of the house is made of light steel, with a width of 3 meters and a length of 6 meters, providing a usable area of approximately 18 square meters. The pre-assembly rate exceeds 90%, with supporting utilities such as water and electricity pipelines, doors and windows, and interior decoration all completed in the factory. On-site, only lifting and connecting the house modules are required, and skilled workers can complete the assembly in one day.
3. Efficient Collaboration: The construction process involves collaborative operations across multiple stages. For example, integrated housing production enterprises in Tangshan operate 24 hours a day, with a daily production capacity exceeding 100 units; transportation fleets dispatch goods as soon as they are produced, ensuring timely delivery of house modules to the site; supporting projects such as electricity and telecommunications are advanced simultaneously, achieving "readiness for water and electricity supply upon completion".

II. Material and Technological Advantages

1. Characteristics of Light Steel Structures: With a light steel framework, these structures are characterized by light weight, high strength, and good seismic performance. Compared to traditional concrete structures, light steel structures can significantly shorten the construction period, and the materials are recyclable, aligning with the concept of green building.
2. Standardization and Flexibility: House modules are designed with standardization in mind, supporting customized specifications and functional layouts. For example, the houses in the Zhengding quarantine site are equipped with beds, air conditioners, water heaters, Wi-Fi, and other living facilities to meet quarantine needs.
3. Environmental Adaptability: Light steel structures are highly corrosion-resistant and, when paired with thermal insulation materials, can adapt to different climatic conditions. Construction is less affected by weather, and even in low-temperature environments (such as winter in Shijiazhuang), progress can be ensured by adjusting construction techniques.

III. Typical Case The construction of the centralized quarantine site in Zhengding County, Shijiazhuang, serves as a typical example:

• Scale and Speed: Within a 500-acre site, 3,000 container houses were assembled in 6 days, with the first batch of 1,008 houses delivered in just 98 hours.
• Technical Support: Drones were used to monitor construction progress in real-time, combined with BIM (Building Information Modeling) technology to optimize construction plans, enabling efficient management of multi-trade cross-operations.
