摘要
基于妈湾跨海隧道工程,综合考虑特长城市隧道、多点进出的工程特点,阐述了妈湾跨海隧道水消防设计思路。提出在传统消防设计的基础上增设泡沫水喷雾自动灭火系统,并合理优化消火栓系统布置间距为30m,增加消火栓干管处联通管的设计,保证消火栓管线环状布置,提高给水保障率,使火灾防护系统更为安全可靠。
Based on the Mawan Cross-sea Tunnel project,this paper comprehensively considers the project characteristics of the extra-long urban tunnel and the multi-point accessing,and expounds the water fire control design ideas of the Mawan Cross-sea Tunnel.It is proposed that foamwater spraying automatic fire extinguishing system should be added on the basis of traditional fire protection design,and reasonable optimization of fire hydrant system layout spacing should be 30 m.The design of connecting pipe of hydrant pipe can be increased,the annular layout of hydrant pipes can be guaranteed,and the water supply support rate can be raised,so that the fire protection system is more secure and reliable.
