摘要
对湖北省兴山县平邑口香溪河特大桥钢管混凝土的配合比和施工工艺进行了介绍,结果表明,该混凝土具有可泵性好、高强、早强、微膨胀等性能;采用锤击、超声波等方法对钢管混凝土进行了检测,检测结果表明钢管内混凝土密实,混凝土与钢管间无缝隙。
This text introduce the match ratio of Steel Pipe concrete and oonstruction techniques of Xiangxihe special bridge in Pingyikou Xingshanxian Hubei province. The oonstruction shows that this kind of concrete have many performance such as pump good,high-intensity, early high-intensity,expanding small. Using hammer, ultrasound and other methods for the detection of steel concrete, testing results showed that the concrete in pipe is very dense and there is no pit between steel pipe and concrete.
