一、引言水沙充填管路的进口能力问题是指喇叭嘴(进口漏斗)与其相毗连的管路初始段设备综合决定的进口能力规律及其他一些有关问题,而问题的中心是进口段能量消耗规律问题。进口能力应理解为:由喇叭嘴条件所决定的单位时间内通过的混合物(砂浆)量(Q_(B·X))许多学者认为:为了合理而有效的工作,应该以一定的水拉(h)淹没喇叭嘴但是他们都没有更全面,更精确的给出这个值,另一方面在生产实践中,鉴别堵管的征兆之一是喇叭嘴
I. INTRODUCTION The import capacity of water and sediment filling pipelines refers to the law of import capacity and other related issues that are decided by the trombone (import hopper) and the initial equipment of the pipelines connected to it. The central problem is the energy consumption of the import section Law problem. The ability to import is to be understood as the amount of mixture (mortar) passed per unit of time, determined by the condition of the bellmouth (Q_ (B x)). Many scholars believe that for a reasonable and efficient work, ) Submerge the trumpets but none of them gives this value more comprehensively and accurately, and on the other hand in production practice one of the signs of identifying tube plugging is the trumpets
