摘要
本文介绍了武汉市江汉三桥钢管混凝土的配合比和施工工艺。施工情况表明 ,该混凝土具有高强、早强、微膨胀的性能。采用锤击、超声波与钻芯取样等检测方法对已填充混凝土的钢管和缀板进行检测 ,检测结果表明 ,钢管内和缀板间的混凝土密实无裂缝 。
? In this article,the mixture rate and construction technological of the concrete filled steel tube of the 3 rd Jianghan Bridge,Wuhan was introlduced.The worksite construction showed the concrete had some properties such as very high strength at the later stage and the early stage,compensating shrinkage.The hammer beating detecting,ultrasonic detecting and boring coredetecting showed that the concrete filled in the tubes and sewed planks was very dense and there wasn't cracks between concrete and steel tube or concrete and sewed planks,that is to say,the combination configuration of concrete and steel tube was rational. 〔
