Made of high-strength PVC-coated membrane formed into curved tubes, it creates a hollow self-stabilizing structure when inflated to high pressure, eliminating the need for metal supports. It withstands snow loads up to 30 cm thick, combining structural support and dust control functions. Integrated steel rails and a PLC control system at the base enable single/multi-module translation, with a daily movement distance of up to 30 meters and precision of ±5 cm, perfectly suited for phased construction and heavy machinery operations.
Real-time monitoring of air pressure, dust concentration, temperature, and humidity allows automatic adjustment of the pressure difference between the interior and exterior. Audible and visual alarms are triggered in case of anomalies, supporting remote control and unattended operation, with an average daily power consumption of only 5–8 kWh. The double-layer membrane + air interlayer design delivers a dust removal efficiency of ≥90% and significant noise reduction. The membrane is 100% recyclable, producing no construction waste and meeting green construction standards.
Factory prefabrication (10–15 days) plus on-site installation (1 day) results in a total project cycle of ≤20 days. With no internal supports, it provides a clear height of 3–5 meters for easy machinery maneuvering, and dismantling takes ≤1 day. Membrane costs are just one-third of steel, significantly reducing construction expenses; materials can be reused 3–5 times, cutting operation and maintenance costs, making the overall cost more competitive than traditional solutions.
It resists wind loads of 6–7 Beaufort scale, and the membrane meets B1 fire resistance standards (self-extinguishing). The intelligent monitoring system provides real-time early warnings, and limit devices on the rails prevent inertial impacts, ensuring all-weather safety.
Applications: Urban rail transit projects, large commercial complex foundation pits, municipal pipeline laying, and high-density urban residential construction.
It supports segmented assembly, expansion, disassembly, and relocation, serving as a new lightweight solution for port bulk cargo handling, urban distribution and transit, temporary stockpiling, and special material storage. It fully meets modern logistics core demands for cost reduction, rapid commissioning, environmental compliance, and flexible expansion.
