摘要
以某火电厂桩基础旋挖灌注桩项目为例,从减小泥浆指标存在的误差、测锤改良成测管、灌注前混凝土用量细化计算及缩短等料时间四个方面介绍粉砂层混凝土灌注桩充盈系数的控制措施。
Taking a pile foundation project of a thermal power plant as an example,this paper introduces the control measures of fi lling coeffi cient of concrete fi lling pile in silty sand layer from four aspects,including reducing the error of mud index,improving the measuring hammer into measuring pipe,refi ning the calculation of concrete dosage before grouting and shortening waiting time for materials.
