| 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. |
