摘　　要：结合国家标准GB50974-2018《消防给水及消火栓系统技术规范》,对储存室外消防用水的消防水池取水口的设置原则进行探讨,并通过实际工程案例进行深入分析。研究表明:1)取水口的设置应充分考虑消防水池最低有效水位,即最大吸水高度与消防车泵轴距地面高度的差值的影响,且最大吸水高度与当地海拔高度密切相关;2)可根据场地面积、市政供水情况、工程造价等因素,选用仅设置取水口、取水口与低压制室外消火栓合用、取水口与临时高压室外消火栓合用等取水口布置形式。实现了便利性、可靠性、安全性等消防水池取水口设置原则。Based on the national standard GB 50974-2018 Technical code for fire protection water supply and hydrant systems , discussed are the principles of fire pool water intake setup for the outdoor fire protection water supply, and analyzed in-depth is a practical engineering case. The studied show that: 1) the minimum effective water level of the fire pool, namely, the difference between the maximum water absorption height and the height between the ground and the pump axle of the fire truck, should be fully considered in the water intake setup, and the maximum water absorption height is closely related to the local elevation;2) the selection of the water intake layout should be based on factors including the site area, the municipal water supply situation and the project cost. Such layout consists of water intake setup only, combined use of water intake and outdoor fire hydrant under low pressure, combined use of water intake and temporary outdoor fire hydrant under high pressure, and so on. Realized are the principles including convenience, reliability and safety.
