Air-Supported Membrane Foundation Pit

Home / Solutions / Excavation Construction / Air-Supported Membrane Foundation Pit

In urban underground space development and large-scale foundation pit engineering, traditional foundation pit support methods suffer from problems such as long construction cycles, high costs, and significant disruption to the surrounding environment, and are prone to safety hazards under severe weather conditions. The air-supported membrane foundation pit solution replaces the traditional support system with an innovative inflatable membrane structure, providing a closed and safe working environment for foundation pit construction. It effectively isolates dust and noise pollution, reduces the impact of construction on surrounding residents and traffic, and withstands severe weather such as wind, rain, and snow, ensuring construction progress and personnel safety. It is particularly suitable for foundation pit projects in urban core areas and sensitive environments.

CORE TECHNOLOGY

Rapid sealing technology

Using a special sealing membrane and a high-efficiency inflation system, the entire foundation pit can be sealed in a short time, effectively controlling dust diffusion and meeting environmental protection construction requirements.

Heavy-load-resistant support technology

The bottom of the membrane is firmly anchored to the foundation around the pit, and with the help of internal air pressure and auxiliary support structure, it can withstand the local loads of construction material stacking and mechanical equipment operation.

Intelligent monitoring technology

Real-time monitoring of membrane air pressure, structural stress and surrounding environmental data; an alarm is issued immediately in case of any abnormality, ensuring a safe and controllable construction process.

Ventilation technology

Equipped with an intelligent fresh air system, the ventilation volume is adjusted according to the number of construction workers and the intensity of work to ensure air circulation inside the foundation pit and avoid the accumulation of harmful gases.

TYPICAL SPECIFICATIONS

Coverage span	30-120 meters
Coverage length	50-200 meters
Height	8-20 meters
Pressure difference	150-250 Pa
Wind resistance level	8-10
Membrane material flame retardancy rating	B1

CORE ADVANTAGE

Rapid deployment without impacting the construction period

The modular design requires only simple assembly and inflation on site, and the foundation pit can be sealed in 1-3 days without affecting the core construction period, helping the project to be delivered on time.

Dual control of dust and noise

The fully enclosed structure effectively blocks the spread of dust, and the membrane material has good sound insulation performance, reducing the impact of construction noise on the surrounding environment and easily passing environmental protection inspections.

Severe weather protection

To withstand severe weather such as wind, rain, ice and snow, and to prevent the foundation pit from being soaked by rainwater or snow load, thus avoiding safety accidents and ensuring continuous construction.

Cost-effective and cost-efficient

Compared with traditional support methods, the cost is reduced by 30%-50%, and it can be disassembled and reused repeatedly. The cost advantage becomes more obvious after multiple constructions.

Intelligent monitoring ensures safety

Real-time monitoring of structural status and environmental data, automatic early warning of abnormal situations, providing comprehensive protection for construction safety.
