钢筋混凝土缺陷危害评估方法与顶升挤浆修复技术

Hazard Assessment Method of Reinforced Concrete Defects and Lift-up Crowded Pulp Repair Technology

根据《混凝土结构工程施工规范》GB50666—2011相关条款,采用科学合理的技术方法修复混凝土缺陷是工程质量控制的重要过程。修复缺陷之前,使用适当的检测方法评估混凝土缺陷的危害性,使用显微镜细观观测数据可以准确判断界面的黏结性能,为制定技术可靠、成本合理的修复技术方案奠定基础,列举工程实例和检测数据,论述了混凝土梁缺陷的危害评估与修复全过程。

According to relevant clause of the Code for construction of concrete structures GB50666—2011,repairing the concrete defects using scientific and reasonable methods is an important process for the engineering quality control. The appropriate test method is applied to evaluate the harmfulness of concrete defects,and using the microscope observation data to judge the interface bonding performance accurately.It is a basement for making the reasonable and reliable repair scheme,and a example is given and detection data are obtained. The defects of concrete beams damage assessment and repair process are described.
