Using Air-Supported Excavation Pit Membrane System, Construction Noise Reduced by Over 40 Decibels!
2026-03-07
Overview
Guangzhou just deployed a massive 9,000-square-meter "air bag" over a construction pit. It blocks 99% of dust and cuts noise by over 40 decibels, keeping the site whisper-quiet (under 60dB) for nearby schools and homes. It’s a huge leap for green, smart city building.
What is an Inflatable Membrane Structure?
Think of it as a giant, rigid tent supported entirely by air pressure. It's lightweight, incredibly strong, and completely column-free.
We already use this proven tech for sports stadiums and massive storage sheds. By popping this over a construction pit, it acts as a "golden shield"—trapping dust and noise inside while creating a comfortable, weather-proof, and temperature-controlled workspace for the crew.

The Inflatable Membrane Structure Consists of Ten Systems
(1) Main Enclosure Structure: Typically uses a new type of environmentally friendly, fireproof, and highly acid/corrosion-resistant PVDF (polyester fiber) architectural membrane material.
(2) Foundation Anchoring System: Anchored by connecting embedded angle steel with the foundation capping beam.
(3) Cable Net Stabilization System: Cable arrangements include local layout, orthogonal grid layout, diagonal grid layout, etc.
(4) Access Control System: Main entrance revolving door, air-lock interlocked doors, emergency doors, and auto-sensing sealed transport channel door systems.
(5) Fresh Air System: 6 to 16 air changes per hour (adjustable), with indoor fresh air no less than 60 m3/h.
(6) Intelligent Control System: Monitoring and automatic control of wind pressure, air pressure, temperature, humidity, lighting, dust, and gas (industrial), as well as intelligent fire protection systems. The inflatable membrane is equipped with 1 indoor temperature and humidity sensor, 1 wind speed sensor, and 1 indoor-outdoor differential pressure sensor.
(7) Emergency Backup System: Backup fan system (one in use, one as backup per set) and a backup diesel generator with an ATS (Automatic Transfer Switch).
(8) Lighting System: Explosion-proof mining lamps (industrial).
(9) Fire Protection System: Intelligent fire water monitors for fire and explosion prevention (industrial).
(10) Dust and Gas Emission System: Electric pressure relief damper. When the pressure is too high, or the concentration of dust, carbon dioxide, or gas is too high, the pressure relief damper opens automatically. The number of pressure relief nets is proportional to the number of air inlets, not exceeding the number of air inlets, and the total exhaust air volume is less than the total supply air volume.

New designs of this "giant air bag"?
1. A Fully Enclosed "Mute Barrier," Calmly Handling Category 14 Typhoons It’s a smart shield. With zero beams or pillars inside, it offers massive open space. The best part? Its IoT sensors allow it to "breathe"—instantly adjusting internal pressure to fight off extreme weather, easily surviving a Category 14 typhoon.
2. The Nation's First Integrated Cooling Function, Warm in Winter and Cool in Summer Inside the Membrane It covers an area bigger than a football field, but feels like an indoor workshop. Special translucent materials let natural sunlight in (saving 60% on lighting), and it’s the first of its kind to feature smart AC to keep workers cool in the summer heat.
3. AI "Super Supervisor" + Construction Robots, Better and Faster Construction Inside, it’s a high-tech playground. AI cameras monitor the site 24/7, spotting risks before they happen. On the ground, 16 different types of construction robots (like 3D-vision tiling bots) do the heavy lifting—working up to 4 times faster than humans with millimeter precision.

Can membrane structures be used to build sports stadiums, and will it be very stuffy?
Membrane sports stadiums are equipped with fresh air systems to ensure indoor air quality and the comfort of athletes. The fresh air system is an intelligent Air Circulation System that feeds fresh air indoors while exhausting stale air through various technical means such as dust removal, filtration, sterilization, dehumidification, and oxygen enrichment.
In areas with severe air pollution such as smog, membrane sports arenas allow sports to be unrestricted by smoggy days, guaranteeing the comfort and safety of exercise.
The fresh air system systematically supplements fresh air into the membrane stadium, effectively preventing the feeling of stuffiness and hypoxia caused by excessive carbon dioxide concentrations.
Additionally, the air provided by the fresh air system is rich in oxygen, which is highly beneficial for sports. High-oxygen air can supply more oxygen to the muscles, increasing human endurance and exercise efficiency, making people feel more comfortable and energetic when exercising inside the membrane.
In high-temperature weather, the inflatable membrane stadium relies on a highly efficient air conditioning system to maintain a comfortable indoor temperature.
The air conditioning system uses efficient cooling equipment, air circulation, and heat exchange technology to ensure rapid cooling and even distribution of cold air.
It can also adjust indoor temperature and humidity in real-time, ensuring that the membrane stadium always maintains a suitable temperature, providing people with an ideal sports experience.
Through the intelligent adjustment of the fresh air and air conditioning systems, the membrane sports stadium achieves fresh indoor air and an appropriate temperature.
Therefore, whether in muggy weather or during intense exercise, people can enjoy a comfortable environment inside the membrane stadium, saying goodbye to stuffiness and discomfort.

FAQ
1. How does the membrane stay up without any internal pillars?
It is supported entirely by internal air pressure! A smart control system continuously pumps fresh air inside to maintain a slight pressure difference. This creates a highly rigid structure while keeping the interior 100% open and obstacle-free for heavy machinery.
2. Is the structure safe during severe storms or high winds?
Absolutely. The system is equipped with IoT weather sensors. If strong winds are detected, the "smart brain" automatically increases the internal air pressure to reinforce the membrane, allowing it to easily withstand up to Category 14 typhoons.
3. Won't it get too hot and stuffy working inside a sealed "air bag"?
This system features an integrated industrial cooling and fresh air setup. It constantly cycles out stale air and pumps in filtered, temperature-controlled fresh air. It feels more like a comfortable indoor workshop than a sealed tent.
