AI Technical Summary
Railway tunnels in cold regions are prone to freezing damage in low-temperature environments. Existing cold protection measures, such as insulation layers, solid insulated doors, or air curtain systems, suffer from aging, high energy consumption, or incomplete coverage, making it difficult to meet the safety, maintenance convenience, and long-term durability requirements of railway tunnels during operation.
A prefabricated air curtain insulation room system for cold-region tunnels is designed, including a prefabricated insulation room main body, connecting components, air curtain jet components, circulating air supply components, and intelligent control components. The air curtain jet parameters are designed based on free jet theory to form a stable and continuous airflow barrier and actively suppress the intrusion of cold air.
Without affecting train traffic, it significantly improves the cold-proof and heat-insulating effect of tunnel entrance sections in cold regions, ensures operational safety, adapts to complex working conditions, reduces energy consumption, and improves the system's operational adaptability and durability.
