摘要
简述了埋地塑料排水管的优点,从管道性能、施工、地基沉降等方面分析了塑料排水管出现变形、脱节、渗漏、破损现象的原因,并以使用普遍的埋地聚乙烯排水管为研究对象,分析了其最大允许覆土厚度,指出当覆土厚度大于4.0 m时不宜采用该管材。
The paper indicates the advantages the buried plastic drainage pipeline,analyzes the reasons for the deformation,detachment,leakage and damages of the pipe from the pipeline performance,construction and foundation settlement,takes the common buried polyethylene drainage pipeline as the research object,analyzes its maximal covering soil thickness,and points out the pipe material can not be used when the thickness of covering soil is greater than 4 meter.
