Outline
To enhance the emergency response capability of subway waterlogging, this study investigated waterbarrier technologies and devices for subways, both domestically and internationally. A systematic review of conventional and innovative subway waterbarrier technologies and devices was conducted, focusing on subway waterlogging risk points such as station entrances/exits, vent shafts, main tracks, and vehicle depots. The advantages and disadvantages of various subway water barrier technologies and devices were analyzed. This study discusses the challenges faced by subway water barrier technologies and devices in terms of cost economy, intelligence, automation, and sustainability. Recommendations are provided for structural optimization, material improvement, multifunctional water barrier devices, intelligent and automated control, green technology, and sustainable development. The results indicate that different waterbarrier devices are suited to various application scenarios. Water barrier devices should be selected based on risk points and flood characteristics. Conventional subway water barrier devices are widely used and are technologically mature. Compared with these technologies, new technologies have advantages in terms of automation, resourcesaving, and improved emergency reliability. This study aims to serve as a reference for the design, installation, and application of subway waterbarrier devices, providing technical support for ensuring the safe operation of subway systems and essentially responding to subway waterlogging.
