With rapid urban development, sand and gravel extraction and foundation pit construction face growing challenges in environmental protection, dust control, operational safety and construction efficiency. Traditional open‑pit methods often cause dust pollution, noise disturbance and material waste, and are highly vulnerable to weather conditions. To solve these pain points, the detachable air‑supported membrane sealing system has emerged as a new green, efficient and reusable solution.
As a lightweight, large‑span structural system, air‑supported membrane structures rely on internal air pressure to maintain shape and rigidity. They offer exceptional advantages including high strength, fast installation, modularity and reusability, making them widely applicable in construction, mining, storage and public facilities.
This study focuses on a detachable, modular air‑supported membrane sealing system designed specifically for foundation pit mining operations. The system effectively seals the construction area, controls dust and exhaust gas, stabilizes the internal environment, and greatly reduces the impact of external weather such as wind, rain and snow. It significantly improves construction safety, continuity and overall efficiency.
The system consists of four core components: high‑strength air‑supported membrane, anchoring and counterweight system, intelligent inflation system, and real‑time monitoring system. The membrane material features excellent tensile strength, tear resistance, weather resistance and durability. The anchoring system ensures stable connection with the foundation pit structure. The inflation system maintains stable internal pressure, usually between 200Pa and 500Pa. The intelligent monitoring platform tracks pressure, air quality, dust concentration and toxic gases to ensure safe and stable operation.
Structural design follows modularization, standardization and intelligence principles. Finite element analysis optimizes the mechanical performance of the membrane surface, allowing appropriate deformation to disperse wind and external loads. This greatly improves structural stability and adaptability to complex geological conditions. Modular design allows factory prefabrication and on‑site assembly, improving construction efficiency by more than 30% compared with traditional methods.
The installation process includes foundation pit preparation, anchoring and counterweight installation, membrane laying, inflation and sealing, and monitoring system commissioning. The entire process is simplified, controllable and highly repeatable. After completion, the system can be disassembled and reused in other projects, reducing material cost and supporting low‑carbon development.
In practical application, the detachable air‑supported membrane sealing system achieves outstanding performance in dust suppression, noise reduction, environmental protection and construction continuity. It provides a closed, stable and controllable working environment, effectively solving long‑standing problems in open‑air foundation pit operations.
Conclusion
The detachable air‑supported membrane sealing system represents an advanced, eco‑friendly and efficient technical solution for foundation pit mining and construction. With the advantages of fast installation, reusability, high stability and intelligent monitoring, it strongly supports green construction, safety management and high‑quality development.
