摘要
我国地埋式污水处理厂结合地面上盖产业综合开发成为一种新的开发模式,具有土地资源集约化、水资源就近利用等优势,但新的综合开发模式消防设计缺乏相关设计规范依据,国内外尚无相关案例,以浙江地区综合开发地埋式污水厂临平第二净水厂项目为研究对象,开展特殊消防设计分析,总结设计要点,以供类似项目参考.项目通过调查研究国外建筑消防设计标准,结合自身特点,从防火分区、防火分隔、火灾荷载控制、人员疏散设计、防排烟设计、灭火系统等方面提出消防设计策略,并采用人员疏散软件STEPS和烟气模拟软件FDS,通过定量计算方式对其整体方案进行消防安全性分析,论证其消防安全性.结果表明,项目采用较大防火分区、地上地下防火完全分隔且分隔楼板防火等级加强的防火分隔方式,以及上下疏散体系完全相互独立等措施策略,项目消防正常运行下可以保障人员安全.
Abstract
The combination of underground wastewater treatment plants(WWTPs)and the comprehensive development of aboveground industries at home has become a new development model,which has advantages such as land resource intensification and nearby water resource utilization.However,the new comprehensive development model lacks relevant design specifications for fire protection design,and there are no relevant cases at home and abroad.Taking the comprehensive development of the Linping Second WWTP project in Zhejiang Province as the research object,a special fire protection design analysis is conducted to summarize the design points,for reference in similar projects.Through investigation and research on foreign building fire protection design standards,combined with its own characteristics,the project proposes fire protection design strategies from the aspects of fire protection zoning,fire separation,fire load control,personnel evacuation design,smoke control and exhaust design,fire suppression system,etc.,and adopts personnel evacuation software STEPS and smoke simulation software FDS.Through quantitative calculation,the fire safety analysis of the whole scheme is carried out to demonstrate its fire safety.The results show that the measures adopted by the project,such as large fire compartment,complete separation of ground and underground fire and strengthening of fire grade of separated floors,and complete independence of upper and lower evacuation systems.It can ensure personnel safety under normal operation of the project fire control.
