城市地下综合管廊供水管道设计

Design of Water Supply Pipeline in Urban Underground Utility Tunnel

介绍了供水管道在综合管廊中的布置原则,以及国标图集中含供水管道舱室典型断面布置,并对国内、国外的多个含有供水管道的管廊舱室布置案例进行了展示和说明。给出了供水管道的几种出舱方式和适用条件;详述了供水管道设计中整体连接钢管以及承插接口球墨铸铁管在管廊内的总体结构布置原则和几种布置形式(包括固定支墩和补偿器的布置方式),以及管道支墩设计的要点;总结了管廊内供水管道钢管、球墨铸铁管及塑料管的管材、连接方式的选择以及工程设计中应注意的问题。

This paper introduced the layout principle of the water supply pipeline in the utility tunnel, briefly described the typical section layout of compartment with water supply pipeline in national standard drawing collection, and illustrated several layout cases of utility tunnel cabin containing water supply pipelines both at home and abroad. Several exit modes and corresponding applicable conditions for the water supply pipeline were given. The overall structural arrangement principle and several layout forms of the integrally connected steel pipes and the socketed ductile iron pipes in the water supply pipeline design were described in detailed, including the ariangement of fixed piers and compensators, as well as the main points of pipe pier design. It also summarized the selection of materials and connections for steel pipes, ductile iron pipes and plastic pipes of water supply pipeline in utility tunnel, and what should be considered in the project design.
