影响城市排水管道经济造价的设计因素

Influence of Design Factor on Economic Construction Cost of Urban Drainage Pipeline

经分析,排水管道的造价主要由管径、埋深、管材几个方面决定,由此阐述设计人员在管材确定、相同流量的条件下,通过不同管径、坡度、管道衔接方式进行搭配调整,从而产生多种设计方案,并对如何确定最经济的设计方案进行探讨。

According to the analysis,the construction cost of drainage pipeline is mainly determined by the pipe diameter,embedding depth,pipe material and etc.The article sets forth that the designers have to select and adjust the different pipe diameters,gradients and pipe connections under the conditions of pipe material determination and the same flows so as to produce several design schemes,and discusses how to determine the most economic design scheme.
