钢管混凝土浇筑质量的检测方法

Test Methods for Quality of Pouring Concrete Filled Steel Tubes

钢管混凝土结构在桥梁上的应用,促进了钢管混凝土在我国的发展。但是钢管混凝土施工过程中浇筑困难,常存在如空洞、脱空、脱黏、混凝土不密实等方面的质量问题,而这些缺陷直接影响其承载能力。因此,开展钢管混凝土内部缺陷检测技术研究,对保证工程质量具有重要意义。

The applications of concrete filled steel tubes structure on bridge promote the development of concrete filled steel tubes in our country,but it is difficult to pour in constructions.There are always some quality problems such as cavities,deformation of displacement,unsticking and concrete is not dense.These defects could affect the carrying capacity of the structure.Therefore,the study on testing technology for internal defects of concrete filled steel tubes is significant for guaranteeing the construction qualities.
