摘要:

根据材料力学原理,结合塑料管道蠕变性能试验数据,给出了架空敷设塑料管道支撑间距的计算方法,并对硬聚氯乙烯(PVC?U)电力护套管和聚乙烯(PE)给水管的支撑间距进行计算,结果表明塑料管道满足综合管廊中架空敷设使用的要求,可为进一步研究塑料管道在水平架空敷设条件下长期性能及产品应用设计提供参考。

Abstract:

This paper provided a methodology for the determination of plastics pipeline span for overhead installation on the basis of the theory of material mechanics and creep test data. This method was applied to calculate the spans of PVC?U pipe for power installations and PE pipe for water supply. The results indicated that the plastics pipeline could meet the requirement for the use of urban integrated pipe gallery. This paper also gives a reference for further study on the long?term performance and applications of plastics pipeline.

Key words: urban integrated pipe gallery, plastics pipeline, overhead installation, span, creep performance
