摘要
首先对农村供水管网管段流量设计计算的传统方法进行了分析,指出其适用条件和局限性。在此基础上,提出了加权人畜用水当量法。该方法结合农村供水的实际情况,既考虑了人畜分布的不均,又考虑了用水量的差别,并且计算公式简单,设计易与实际相一致,是一种计算农村供水管网管段设计流量的有效方法。
The traditional methods for calculating the pipe-segment design discharge in rural water-supply network system are analyzed first of all, and their application conditions and limitation are indicated. On the basis of these analyses, a new method for calculation of pipe-segment design discharge in rural water-supply network system, which is called as water consumption equivalent-weight method of human and livestock, is proposed. Associated with the practical rural situation, this method considers not only the disproportion of human and livestock distribution but also the difference between human and livestock water consumptions. More over, its calculation formula is very simple, and the designed water consumption approaches to practical water consumption. Results of calculation show that the new method is an effective way for calculating the pipe-segment design discharge in rural water-supply network system.
