地下工程排水管材中,钢筋混凝土管和塑料管在性能和价格方面差异比较大。分析、比较了钢筋混凝土管、高密度聚乙烯(HDPE)双壁缠绕管、玻璃纤维增强塑料夹砂管、离心浇铸聚酯高强度夹砂复合玻璃钢管等4种管材的性能和价格。介绍了不同排水管管材在工程中的选择和应用。 Drainage pipe works underground, reinforced concrete pipe and plastic pipe in the performance and price differences are relatively large. The performance and price of four kinds of pipes, such as reinforced concrete pipe, HDPE double-wall winding pipe, glass fiber reinforced plastic pipe, centrifugal casting polyester high strength sand composite glass pipe were compared and analyzed. The selection and application of different drainage pipes in the project are introduced.
