Qinghai Prefabricated Houses

Qinghai prefabricated houses have formed an innovative development model adapted to the fragile alpine environment through ecological protection, technological adaptation, and policy guidance.

1. Ecological Protection-Oriented Construction Model
Around Qinghai Lake, prefabricated concrete houses are used for the relocation and resettlement of agricultural and pastoral households. The “unified planning and construction” model shortens the construction period and reduces long-term disturbances to the alpine ecology caused by traditional cast-in-place construction. For example, the project in Daotanghe Town, Gonghe County, Hainan Tibetan Autonomous Prefecture, reduces construction pollution through modular design. Xunhua Salar Autonomous County transforms damaged old livestock pens into new prefabricated ones, achieving resource recycling. In 2024, Qinghai launched a pilot program for subsidies on the purchase of agricultural machinery for prefabricated livestock pens, promoting the replacement of traditional buildings with modular breeding facilities to further reduce ecological damage.

2. Lightweight Applications in Cultural and Tourism Scenarios
In the hinterland of the Qilian Mountains, prefabricated buildings such as modular starry sky houses and space capsules are used. Their rapid deployment and detachable design meet tourists' experience needs while avoiding permanent damage to the fragile ecology. These buildings adopt light steel structures and high-performance insulation materials, adapting to the climate characteristics of strong ultraviolet radiation and large diurnal temperature variations in the plateau, balancing functionality and ecological friendliness.

3. Industrial Upgrading and Technological Localization
Local enterprises have established the first full-industry-chain prefabricated building base in northwest China, forming automated production lines with products covering residential buildings, public buildings, and temporary facilities. Through BIM digital management platforms and environmentally friendly processes, they achieve precision control and durability assurance of components. For example, enterprises in the Xining Economic and Technological Development Zone have optimized material formulations for high-altitude environments, enhancing product resistance to freeze-thaw cycles and corrosion, which have been applied in multiple plateau projects.

4. Technological Standards and Livelihood Adaptation
Prefabricated houses are cast as a whole using national standard deformed steel bars and C35 concrete, with wall thicknesses ranging from 0.18 to 0.24 meters, capable of withstanding earthquakes below magnitude 8. They integrate water and electricity pipelines with interior decoration systems for “plug-and-play” functionality. The specifications are flexibly adjustable (length: 5-9.5 meters, width: 3-4 meters, height: 2.8-3.2 meters), suitable for scenarios such as new rural construction, homestays, and emergency facilities. The government prioritizes their promotion through projects like the comfortable housing project and earthquake resistance renovations, requiring the formulation of local technical specifications to adapt to plateau climate needs.

5. Policy Support and Market Cultivation
Qinghai has incorporated prefabricated houses into key areas such as the comfortable housing project and lakefront construction, promoting the development of the local industrial chain through policies like agricultural machinery subsidies and industrial base cultivation. Enterprises focus on standardized management, establishing technical teams to provide customized solutions, ensuring construction quality meets industry standards, and gradually enhancing public awareness.
