摘要:
港珠澳跨海集群工程海底隧道是目前世界上最长的公路沉管隧道,运营期设置有主动与被动的双重防火系统。结合港珠澳海底沉管隧道的主要技术特点,提出防火设计中热释放率、火灾次数、耐火等级以及采取防护措施后构件的主要耐火指标。依据工程防火的具体实施条件,通过综合比较,沉管结构防火设计采用防火板直接覆面方式,沉管接头防火采用由刚性防火板与柔性防火隔断共同组成的具有自主知识产权的双层防护系统。
关键词: 港珠澳, 沉管隧道, 被动防火, 结构防火, 接头防火, 防火板
Abstract:
At present, the immersed tunnel of Hong KongZhuhaiMacao Link is the longest highway immersed tunnel in the world, which has active fire prevention system and passive fire prevention system. The main technical characteristics of Hong KongZhuhaiMacao Immersed Tunnel are summarized; and then the heat releasing rate, fire frequency, fireproofing rating and fireproofing standards of tunnel components are proposed. According to fire prevention conditions, fire prevention board is used for immersed tunnel segment structure; the rigid fire prevention board and flexible fire prevention board are used for immersed tunnel segment joints.
Key words: Hong KongZhuhaiMacao Link, immersed tunnel, passive fire prevention, structure fire prevention, joint fire prevention, fire prevention board
