室内消火栓保护半径的设计计算

Design Calculation of Protection Radii of Domestic Hydrants

通常消火栓水枪的充实水柱及消火栓保护半径计算公式多以水枪上倾角为45°来考虑 ,这种做法有一定的局限性 ,不能充分发挥消火栓充实水柱的作用。本文提出充实水柱可以大于规范要求的最小充实水柱 ,减少消火栓的设置数量。在满足消防安全的前提下 。

The calculation formulae for the substantial water columns of the water guns of hydrants and for the protection radii of hydrants in most cases assume an upper angle of inclination of 45° for water guns.This practice has certain limitation and cannot give full play to the substantial water columns of hydrants.It is considered in this paper that substantial water column may be bigger than the minimum water column required by the codes so that the number of hydrants to be installed can be reduced.
