新型钢筋混凝土管用于高流速山地排水工程

Application of New-type Reinforced Concrete Pipes to High Flow Rate Drainage in Mountainous Region

结合南宁经济技术开发区某道路工程,对比了2006版和1997版《室外排水设计规范》对排水管道最大流速的不同要求,认为按新版规范进行设计可大大节省工程投资。该工程还采用了芯模振动钢筋混凝土排水管,介绍了其生产工艺、性能及流速适用范围,实际运行表明,该管道适用于高流速山地排水工程。

Combined with a road drainage engineering in Nanning Economic and Technical Devel- opment Area, the different requirements for maximum flow rate in drainage pipe specified in the Code for Design of Outdoor Sewerage Engineering of 2006 and 1997 editions are compared. It is considered that the design based on new edition code can greatly save the engineering cost. The core mould vibration-reinforced concrete drainage pipes were used in this engineering. The production process, performance and application scope of this pipe are introduced. The operation results show that this pipe is suitable for the high flow rate drainage in mountainous region.
