我国城镇市政排水管相关标准中入渗控制的探讨

Discussion infiltration control in the standard for urban municipal drainage in China

我国城镇市政排水管渠结构性和功能性病害严重,排水管入渗率较高。通过比较分析我国城镇市政排水管道相关标准中入渗控制要求,结合实际工程中出现的问题,提出补充混凝土及钢筋混凝土排水管标准中抗渗性指标和密封性条款、完善排水管道验收标准中闭水试验允许渗水量的建议要求,为日后修订排水管相关标准提供参考。

The structural and functional disease of municipal drainage is serious in China,and the infiltration rate of drainage pipes is higher.Compared and analyzed the infiltration control requirements in the standard of urban municipal drainage in China,the paper produces some advices and requirements in combination with project practice,that supplement the impermeability indexes and sealing clauses in the standards of concrete and reinforced concrete drain pipes,and improve the allowable seepage in the closed water test in the acceptance standard of municipal drainage,so as to provide reference for the revision of the relevant standards of drainage in the future.
