摘要
针对CRTSⅢ型板式无砟轨道自密实混凝土施工过程中的操作和管理不规范进行了探讨。阐述了自密实混凝土施工流程和技术指标,建立起标准化质量管理体系,明确了质量控制要点。对自密实混凝土施工全过程中原材料及拌和物质量控制、模板安装等环节易出现的问题进行梳理,并提出相应措施。分析了自密实混凝土内部质量无损检测方法,建议采用超声反射法。
The nonstandard operation and management in the construction process of self-compacting concrete in CRTSⅢslab ballastless track were discussed.The construction process and technical index of self-compacting concrete were expounded,the standardized quality management system were established,and the key points of quality control were clarified in this paper.The problems in the whole process of self-compacting concrete construction was sorted out,including quality control of raw materials and mixtures,formwork installation,etc.,and the corresponding measures were put forward.The non-destructive testing method for internal quality of self-compacting concrete was analyzed to recommend the ultrasonic reflection method.
