钢筋混凝土压力管与其它管道相比具有坚固、可靠、耐久,输水能力长期不变的优点,因此广泛应用于各类输水管道建设中。水力振动成型是目前生产钢筋混凝土压力管较先进的方法。由于对钢筋混凝土压力管的内表面质量缺乏明确的要求和标准以及生产中对内表面质量缺乏必要的监测,因此现在生产的钢筋混凝土压力管的内表面质量不高。而计算表明,由于粗糙度不同,同一管径管道的过水能力有时相差20～3O％,水力阻力相差2～2.5倍。这就意味着,当粗糙
Compared with other pipelines, reinforced concrete pressure pipes have the advantages of being sturdy, reliable, durable, and long-term water transfer capacity. Therefore, they are widely used in the construction of various types of water pipelines. Hydraulic vibration molding is currently a more advanced method for producing reinforced concrete pressure pipes. Due to the lack of clear requirements and standards for the inner surface quality of reinforced concrete pressure pipes and the lack of necessary monitoring of the inner surface quality in production, the quality of the inner surface of the currently produced reinforced concrete pressure pipes is not high. The calculations show that due to different roughness, the water capacity of the same pipe diameter sometimes differs by 20 to 30%, and the hydraulic resistance varies by 2 to 2.5 times. This means that when rough
