雨污水管道入廊技术分析

Analysis on the design of rain & sewage system in urban utility tunnel

雨污水管道入管廊后对管廊的走向、坡度、埋深、横断面尺寸都会造成影响,进而对管廊造价有很大影响。针对雨污水管道特点,对管廊断面、纵断面、支线衔接、管材选择、管道清疏等方面进行分析和探讨,从而为相关工程设计提供参考。

Putting the rain sewage pipe into urban utility tunnel will change the trend,slope,depth and cross-section size of urban utility tunnel. The additional ventilation facilities and design alteration may cause to raise the price of the municipal engineering project. In view of the construction characteristics of rain sewage pipeline and urban utility tunnel,this paper analyzes the key points of design,including vertical section,branch line connection,pipe material and pipeline dredging,etc. So as to provide reference for the related engineering design.
