【Abstract】 With the large-scale development and utilization of urban underground space, the research and development of protective equipment involved in the field of civil air defense keep pace with the times, such as rail transit, underground passage and so on. In recent years, a new type of super high strength steel fiber reinforced concrete sealing board for horizontal protection is developed. This kind of blocking board has reasonable overall design, high installation efficiency, quick conversion in battle, and high economic and social benefits. In this paper, the installation position, structure, technical requirements and installation steps of the sealing plate are discussed for reference.更多还原
