Foundation pit construction has traditionally been an open-air operation, where wind, rain, dust, and noise often affect both progress and the surrounding environment. With the development of the foundation pit air dome, this conventional method has gradually shifted toward a new stage of indoor construction.
1. Weather Resistance: Enabling All-Weather Construction
In the past, foundation pit construction was significantly constrained by weather. Rainy and snowy days turned construction sites muddy, making it difficult for machinery to operate, increasing worker safety risks, and frequently delaying progress. The air dome fully covers the construction site, protecting the internal environment from wind, rain, and snow. Even under adverse conditions, the construction process can continue smoothly, significantly improving schedule stability.
2. Reducing Pollution: Less Noise and Dust
Dust and noise are two major problems in urban construction management. The enclosed structure of the foundation pit air dome can block approximately 90% of dust, significantly improving surrounding air quality. It can also reduce noise by about 80%, minimizing the impact on nearby residents and creating a more harmonious relationship between construction sites and communities.
3. Structural Advantages: Creating a Spacious Open Space
The foundation pit air dome is an air-supported structure without beams or columns. It relies on the pressure difference between the inside and outside of the membrane to maintain stability. This not only simplifies the construction process but also provides a large open space—over 50 meters in height—allowing large machinery and equipment to enter and operate more easily, thereby improving construction efficiency.
4. Material Performance: Multiple Protections of PVDF Membrane
The PVDF membrane, the core material of the air dome, offers outstanding performance. It blocks about 90% of UV rays, protecting staff and equipment. It also provides excellent thermal insulation and heat dissipation, reducing heat in summer and retaining warmth in winter, thus maintaining a suitable construction environment. In addition, it is B1 fire-retardant, offering reliable safety assurance.
The foundation pit air dome not only reduces construction-related pollution but also demonstrates strong potential for promoting green, efficient, and environmentally friendly construction. With advantages such as dust and noise reduction, weather resistance, optimized space, and enhanced safety, the air dome is transforming foundation pit construction from traditional open-air methods to indoor solutions, bringing new momentum to the sustainable development of the construction industry.
