市政雨水管道渗水、漏水现象相当普遍,已经成为市政工程的主要质量隐患,其危害十分重大。因雨水管道渗水,导致管基、掖角、管顶等部位下沉、塌陷,使路面失去支撑,而失稳破坏,轻者会造成线性裂缝、网状裂缝,重者局部路面破坏、沉陷,甚至出现大坑,严重威胁通行者的生命及财产安全。全面分析了雨水管道产生渗漏的原因,并提出相应的预防措施,旨在为同类工程提供借鉴。 Municipal rainwater pipe seepage, leakage is quite common, has become the main quality of municipal engineering hidden dangers, the harm is very significant. Due to the seepage of rainwater pipes, subsidence and collapse of the pipe foundation, the tipping angle and the top of the pipe will cause the pavement to lose support and destabilize, and the light will cause linear cracks, net-like cracks, heavy road pavement damage, subsidence, Even the emergence of big pit, a serious threat to the lives of passers-by and property safety. A comprehensive analysis of the causes of leakage of rainwater pipes, and put forward corresponding preventive measures designed to provide reference for similar projects.
