建筑小区给水管网水力计算的探讨

Discussion on pipe network hydraulic computation of water supply in a building estate

针对建筑小区用水特点 ,就目前小区给水水量计算常用的设计秒流量计算公式及最大时流量计算公式 ,结合工程实践 ,进行管网平差计算 ,并对其成果作经济分析比较 ,结果表明前者计算成果其管径、设备选型所需费用高于后者。为此 ,根据实践调查和分析 ,建议建筑小区给水水量计算采用最大时流量公式乘以建筑小区配水管网不均匀系数进行管网水力计算。

In view of water characteristics of a building estate, for formulas of calculation of design flow per second and maximum flow per hour used in water supply yield computation in the building estate at present, combining with engineering practice, the writer does pipe network adjusted computation, and economically analyses and compares its results. The result states clearly that required cost of lectotype of caliber and equipment in the calculation result of the former exceeds it of the latter. According to practical investigation and analysis, the writer suggests to do pipe network hydraulic computation with which formula of maximum flow per hour is multiplicated by distribution system of water supply non?uniform coefficient in the building estate in water supply yield computation in the building estate.
