With the iterative upgrading of urban construction, environmental protection, safety and efficiency in foundation pit construction have become core project requirements. Especially for rail transit, municipal pipe gallery and other projects in urban core areas and residential neighborhoods, there are strict dust and noise control standards as well as construction space constraints. As a professional air membrane manufacturer, we have launched sliding rail foundation pit air membranes with an innovative design of "rail movement + air rib support", solving the pain points of traditional foundation pit protection and becoming an excellent solution for modern green construction.
Sliding rail foundation pit air membranes feature outstanding core advantages and are precisely suitable for various foundation pit construction scenarios. Compared with traditional fixed canopies, they adopt high-strength PVC/PVDF coated membrane materials, forming a hollow self-stabilizing structure through inflated air ribs. Equipped with ground steel rails, they can realize flexible overall translation, meeting the needs of long and narrow foundation pits, phased construction and other scenarios. This technology has been successfully applied in Jinan Rail Transit Line 7 Project, achieving a win-win situation for construction and environmental protection. Meanwhile, the product is available in two types: sliding rail air rib type and industrial air supported type, covering an area from 300 to 5,000 square meters. Customization is available to suit diverse construction scenarios such as subways, commercial complexes and residential projects.
High efficiency, convenience, cost reduction and efficiency enhancement highlight the core value of the technology. Sliding rail foundation pit air membranes adopt factory prefabrication plus on-site rapid installation, with an overall construction cycle of only 15 to 35 days, greatly improving efficiency compared with traditional canopies. The membrane materials are recyclable, reducing the overall cost by 30% compared with traditional schemes, significantly lowering the initial investment and operation and maintenance costs for constructors. The intelligent control system monitors air pressure and dust concentration in real time for unattended operation, balancing environmental protection and energy conservation.
Safe, compliant and eco-friendly, it aligns with policy development trends. Amid increasingly strict environmental protection policies, the fully enclosed design of sliding rail foundation pit air membranes achieves a dust control efficiency of ≥95%, effectively restraining the diffusion of PM2.5 and PM10, and providing remarkable noise isolation. It fundamentally solves the problem of construction disturbance to residents and avoids environmental penalties. The membrane materials meet B1 class fire protection standards, resist wind loads of Grade 6 to 9, and withstand rain and snow, creating an all-weather enclosed working space to ensure safe and orderly construction and help projects achieve compliance.
As a strong manufacturer deeply engaged in the air membrane field, we provide a complete set of R&D, design, production, installation and operation services, offering one-stop solutions from customized planning to on-site implementation. In the future, we will continue to upgrade our technologies, and with better products and services, support the green transformation of the construction industry and safeguard various foundation pit construction projects.
