泵送混凝土最常见的故障是管道堵塞而造成压送中断。堵塞次数过多,不但影响浇灌速度,有时还会引起质量事故。因此,分析堵塞原因,研究防止对策,常常是推广应用泵送混凝土的关键问题。
The most common failure of pumped concrete is the clogging of pipelines and the interruption of pressure transmission. Excessive jams not only affect the speed of watering, but can also cause quality accidents. Therefore, the analysis of the cause of the blockage and the study of countermeasures are often the key issues in promoting the application of pumped concrete.
