上盖开发式车辆段射流通风与消防排烟研究进展

Research progress of jet ventilation and fire smoke exhaust in development type car depot with upper cover

盖下列车运用库属于地下超大空间,目前没有相关规范来指导该类建筑的通风消防设计,故其通风及防排烟设计是目前急需解决的问题。针对该问题,从火灾危险性、火灾载荷、排烟、通风、人员疏散等五方面对列车运用库进行全面综述,总结了目前存在的主要问题,提出射流通风协同机械排烟方式应该是该类建筑的通风与消防排烟相结合的发展趋势。

The under cover train operation depot belongs to the underground super large space,and there is no relevant specification to guide the fire protection design of such buildings at present,so its ventilation and smoke control design is an urgent problem to be solved at present.In view of this feature,the fire characteristics of the under cover train operation depot are analyzed from the perspectives of fire risk and load,and the research progress of jet ventilation and fire smoke exhaust in the upper cover development type depot is summarized in combination with the smoke exhaust system,ventilation system and ventilation smoke exhaust coordination system of the operation depot,and the existing problems in the current research are proposed.The results show that there is a contradiction between the fire protection design of the upper building and the lower building,the fire protection effect of the firewall separation design is poor,and the air duct system is difficult to meet the fire protection requirements,so the induction ventilation system without air duct should be used.
