摘　　要：综合分析了市政给排水系统中排水管材的选择问题。文章首先概述了排水管材在市政给排水系统中的重要性。接着,文章详细归纳了当前国内市政排水管道中主要使用的六种管材,包括钢筋混凝土管、聚乙烯缠绕结构壁管、聚乙烯塑钢缠绕管、钢带增强聚乙烯波纹管、HDPE双壁波纹管和玻璃钢夹砂管。进一步地,文章提出了排水管材的选用原则,包括考虑管道的粗糙系数、足够的结构强度以及较低的经济成本。最后,文章通过广州市和武汉市两个市政项目的实际案例,展示了如何根据具体工程条件、地质条件、施工条件及建设周期等因素,合理选择排水管材,以确保工程的安全可靠和经济性。综上所述,本文的研究成果对于指导未来市政给排水系统中排水管材的选择具有重要的理论和实践意义。This paper comprehensively analyzes the selection of drainage piping materials in municipal water supply and drainage systems.Firstly,it outlines the importance of drainage piping materials in municipal water supply and drainage systems.Subsequently,the paper details six major types of piping materials predominantly used in municipal drainage pipelines in China,including reinforced concrete pipes,polyethylene spiral wound structure-wall pipes,polyethylene steel-plastic spiral wound pipes,steel strip reinforced polyethylene corrugated pipes,HDPE double-wall corrugated pipes,and fiberglass reinforced plastic mortar pipes.Furthermore,the paper proposes principles for selecting drainage piping materials,including considerations for the pipe's roughness coefficient,sufficient structural strength,and lower economic cost.Finally,through practical cases from two municipal projects in Guangzhou and Wuhan,the paper demonstrates how to reasonably select drainage piping materials based on specific engineering conditions,geological conditions,construction conditions,construction periods,and other factors to ensure the safety,reliability,and economy of the projects.In summary,the research findings of this paper have significant theoretical and practical implications for guiding the selection of drainage piping materials in future municipal water supply and drainage systems.
