摘要
为避免钻孔灌注桩因首批混凝土灌注量不足而导致水或泥浆进入导管，影响灌注桩的质量，按《公路桥涵施工技术规范》中公式计算的首批混凝土灌注量应乘以扩孔系数。
To avoid water or slurry entering the tremie and affect the quality Of the bored pile due to insufficient concreting the first batch, a formula from the Specification for Construction OfHighway Bridges and Culverts is used for the calculation, i. e. the first batch of concrete shall bemultiplied by reading coefficient.
