Project Background
During the construction of the research building at Sichuan Provincial People’s Hospital, minimizing environmental impact became a critical requirement. The project site was located adjacent to active hospital facilities where construction dust and noise could directly affect patients, medical staff, and nearby residents.
Traditional open-pit construction methods often generate large amounts of airborne dust and continuous noise pollution. To address these challenges while maintaining construction efficiency, the project team adopted an innovative air-supported membrane enclosure system.
This temporary construction air dome created a controlled environment above the excavation area, significantly reducing environmental disturbance throughout the construction process.
Why Construction Air Domes Are Used for Sensitive Building Sites
Construction projects near hospitals, schools, transportation hubs, and residential communities often face strict environmental requirements.
Compared with conventional temporary barriers, air-supported membrane structures provide a more effective solution by creating a fully enclosed workspace.
Key advantages include:
- Superior dust containment
- Significant noise reduction
- Improved site safety
- Weather protection during construction
- Reduced impact on surrounding communities
For projects located in environmentally sensitive areas, air dome systems have become an increasingly popular solution for sustainable construction management.
Engineering Solution: PVC Inflatable Membrane Structure
The project utilized a PVC double-layer inflatable membrane structure installed directly above the construction pit.
The enclosure covered approximately 1,200 square meters with a maximum span of 44 meters and a height of 6 meters.
The system operates by maintaining controlled air pressure between the membrane layers, allowing the structure to remain stable while creating a fully enclosed environment.
Key Technical Features
- PVC-coated membrane material
- Double-layer air-supported system
- Lightweight temporary construction enclosure
- Rapid installation and removal
- Low operational energy consumption
The hollow cavity between the inner and outer membrane layers also provides additional acoustic insulation, helping absorb and block construction noise before it reaches surrounding areas.
Dust and Noise Reduction Performance
One of the primary goals of the project was to minimize the impact of construction activities on nearby hospital operations.
According to project monitoring data:
Environmental Results
✔ Dust emissions reduced by more than 90%
✔ Noise levels reduced by approximately 60%
✔ Improved environmental conditions around the construction site
✔ Reduced disruption to patients and neighboring communities
These results demonstrate the effectiveness of membrane-based construction enclosures as an environmentally responsible alternative to traditional site protection methods.
Why PVC Air Domes Are Effective for Construction Site Protection
Compared with traditional steel hoarding systems or temporary fencing, inflatable membrane structures provide a fully enclosed construction environment.
Benefits include:
Better Dust Control
The sealed membrane enclosure prevents airborne particles from escaping the construction area.
Enhanced Acoustic Performance
The double-layer membrane system helps absorb and dissipate noise generated by excavation and construction activities.
Faster Installation
Prefabricated membrane systems can be installed significantly faster than conventional enclosure structures.
Sustainable Construction Management
Reduced environmental impact helps contractors comply with increasingly strict urban construction regulations.
Applications of Construction Air Dome Systems
Air-supported membrane structures are widely used in:
- Hospital construction projects
- Metro station construction
- Urban excavation sites
- Industrial facility upgrades
- Environmental containment projects
- Temporary warehousing
- Mining and bulk material storage
