“互联网+城乡供水”改造工程中不同管网方案比较和选择——以泾源县“互联网+城乡供水”提升改造工程为例

Comparison and Selection of Different Pipe Network Schemes in the"Internet+Urban and Rural Water Supply"Reconstruction Project-Taking the"Internet+Urban and Rural Water Supply"Upgrading and Reconstruction Project in Jingyuan Countyas an Example

通过对泾源县“互联网+城乡供水”提升改造工程管网中不同管材、管线穿路方式和阀井结构等进行分析比较,得出了输供水压力管道采用球墨铸铁管和PE管两种管材、管线穿路方式采用破路开挖并恢复的方式进行施工、联户阀井采用边预制边安装施工的大块预制钢筋砼阀井、分水阀井采用现浇砼结构型式、管网监测阀井采用监测井与分水井结合布置,从而为其他同类工程建设提供参考。

By the analysis and comparison of different pipe materials,pipeline routing methods and valve pit structures in the pipeline network of the"Internet+urban and rural water supply"upgrading and reconstruction project in Jingyuan County,this paper concludes that the pressure pipeline for water transmission and supply uses the two pipe materials of the nodular cast iron pipe and the PE pipe,the pipeline routing method is to construct by the way of road breaking,excavation and restoration,the joint valve pit uses the large prefabricated reinforced concrete valve pit which is installed while prefabricated,the water diversion valve pit adopts a cast-in-place concrete structure type,and that the monitoring valve pit of the pipeline network is arranged in combination with the monitoring pit and the water diversion pit,so as to provide reference for other similar engineering construction.
