Air-Supported Urban Deep Excavation Enclosure System

Overview & Engineering Scope

Primary Application Environment

Designed for deep foundation pits in high-density downtown construction zones, subway hubs, and commercial centers where spatial constraints prevent traditional scaffolding.

customer challenges Addressed

Stop facing daily municipal fines from dust emissions, local noise complaints during night digging, and costly project downtime triggered by unexpected heavy rainfall.

Technical Specifications & Features

Structural Integrity

Fabric Engineering

Utilizes PVDF/PVC coated structural membrane with high tensile strength (6000/5500 N/5cm) and UV resistance.

Pressure & Anchoring Systems

Features automated smart inflation controls paired with heavy-duty concrete ground anchoring to withstand 120 km/h winds.

Environmental Control Systems

Active Dust Suppression

Creates an enclosed micro-environment to contain 99% of particulate dust generated by heavy machinery.

Noise Abatement Technology

Multi-layer acoustic membrane panels attenuate construction noise by up to 18 dB across surrounding neighborhoods.

Scenario-Specific Advantages

• Unobstructed Crane Movement: Column-free design allows excavators and trucks full range of motion.
• Zero Weather Downtime: Keeps foundation soil dry, preventing slope degradation during rainstorms.
• Rapid Deployment: Installs in days without complex structural foundation requirements.

Frequently Asked Questions

How does the system handle high wind loads?

Smart pressure sensors automatically adjust interior air pressure during storm events to maintain structural rigidity.

Can heavy machinery enter and exit easily?

Yes, customized airlock vehicle access doors allow continuous dump truck and loader transit without pressure loss.
