农村饮水工程中挑选管材的简捷方法

Tubular Product Selection in Rural Drinking Water Project

在农村饮水安全工程施工中,挑选管材可综合考虑水流在供水管道中的经济流速、管道材质、承压能力、管长、糙率、流量及管道单位管长的投资系数等多种因素,结合工程所处地理位置、地形、地质等具体实际情形,灵活选择挑选管材简捷法不同公式,计算出满足用水户不同要求同时又经济适用的管材,该方法可为农村饮水安全工程供水管道设计提供借鉴.

The selection of pipe material and approaches are introduced in this paper, considering the factors of water pipe- line, water pipeline geographical environment parameters and the heterogeneous unit length of investment coefficient, and the calculation formula is deduced to choose safe, economic, applicable pipe combined with the situations of the engineer- ing geographic position and geology type, which can be used in the design of rural drinking water safety engineering for ref- erence.
