钻孔灌注桩排渣泥浆流速的计算

Calculation of Up Speed Rate of Cutting Removal for Bored Piles

针对目前钻孔灌注桩施工时,在确定冲孔方案时没有定量分析,往往造成排渣不净,沉渣过多的现象,结合实例,介绍了冲孔排渣泥浆流速计算的方法。

In current bored pile drilling, the cutting in borehole is not be able to clean up efficiently and there is excessive settled cutting due to lacking of quantitative analysis on determination of borehole cleaning up. Aiming to resolved this kind of problems, calculation methods of cutting removal speed rate were introduced, taking the actual cases as samples.
