诸暨保利剧院消防给水系统设计

Design for the Fire Protection Water Supply System of Zhuji Poly Theatre

诸暨保利剧院由A区剧院和B区影院两部分组成,剧院复杂的空间结构、人员密集度以及易燃物多的高火灾危险性决定了其消防给水系统的复杂性。本工程消防给水系统主要包括消火栓系统、自动喷水灭火系统、自动扫描射水高空水炮系统、雨淋系统、水幕冷却系统等。详细介绍了各消防给水系统的消防水源、水量以及设计参数。同时,针对设计中的难点,如舞台及观众厅上空的消火栓及喷淋的设置、雨淋系统的分区及控制、消防干管敷设方式与舞台机械的结合、水幕喷头的设置部位及水幕系统的延续时间、水泵接合器的设置数量与方式以及消防排水的定量等,进行了详细分析探讨。

The Poly Theatre in Zhuji is integrated of District A theatre and District B cinema. The complexity of the fire protection water supply system is determined by the high potential of fire hazards due to its complex space structure, high population assembly and a lot of inflammables. The fire protec- tion water supply system of this project contains hydrant system, sprinkler system, automatic-scanning el- evated fire monitor extinguishing system, deluge system and drencher system. The water demand and de- signing parameters of the fire water supply were introduced in detail. Meanwhile, there were many diffi- culties and key points in the designing process were analyzed and studied such as the hydrant and sprin- kler settings over the stage and auditorium, the deluge system distribution and control, the integration of the main hydrant pipe and the stage mechanics, the sprinkler setting position of the drencher system and fire extinguishing duration, the number and setting mode of the fire department connection, and the ration of the fire protection drainage.
