市政地下排水管道常见病害成因及防治分析

Analysis on the Causes and Prevention of Common Diseases of Municipal Underground Drainage Pipelines

随着城市规模的扩展,城市排水能力面临巨大考验。管道老化、腐蚀、失修、“跑冒滴漏”现象明显,易发生淤塞、内涝、污染,甚至导致路面塌陷,存在非常严重的安全隐患。除管道规划因素外,施工不规范是导致各类管道问题频发的主要原因。本文从多角度出发,对市政工程地下雨污水排水管网常见的病害成因及防治方案进行分析。

With the expansion of urban scale,urban drainage capacity is facing a huge test.The pipelines are aging,corroded,out of repair,and"running,dripping and leaking"phenomena are obvious,and they are prone to siltation,waterlogging,pollution,and even road collapse,which poses very serious safety risks.In addition to pipeline planning factors,irregular construction is the main reason for the frequent occurrence of various pipeline problems.From multiple perspectives,this article analyzes the causes of common diseases in the underground rain and sewage drainage pipe network of municipal engineering and their prevention and control plans.
