火灾工况建筑消防水池补水量的合理计算

Reasonable calculation of supplementary water capacity for fire cisterns of architectures

在消防水池补水量的计算方面,设计人员通常采用假定进水管流速的方法来计算,这种计算方法显然缺乏理论依据,其计算所得结果必然影响消防给水系统的安全性、投资。文章通过理论推导方法探讨了补水量合理计算的问题,并推导出补水量的计算公式,简化了水力计算,既可减少消防水池容积,又可满足火灾时消防用水的需要。

Estimated water inlet pipe's flow rate is commonly adopted to calculate supplementary water capacity of fire cisterns of architectures, the calculating method of which lacks theoretical basis. It is inevitable that the result of the calculation would influence the safety and investment of fire water supply systems. The problem of reasonable calculation of supplementary water capacity is approached in theory, and a calculating formula for supplementary water capacity is deduced. Such calculation method can simplify hydraulic calculation, and help decrease the volume of fire cisterns while maintaining sufficient water capacity for fire fighting.
