混凝土结构裂缝控制与灌浆法处理技术

Control and Grouting Treatment Technology of Concrete Structure Crack

简要分析了混凝土裂缝产生的原因、裂缝控制措施、设计和施工中采取的其他措施,以及混凝土裂缝的常用处理方法,并以箱涵和隧道工程裂缝处理为案例,介绍了灌浆法处理技术。结果显示:现场检查裂缝处外观裂缝基本消失,满足规范要求;后续进行钻孔取芯检测,原缝隙全部充填密实,外观效果良好,对芯体的抗压强度试验也全部满足设计要求,达到预期目的。

This paper briefly analyzes the concrete crack cause, crack control measures, other measures taken in the design and construction, and the common treatment methods of concrete crack. Taking the crack treatment of box culvert and tunnel engineering as an example, this paper introduces the grouting treatment technology. The result shows that the appearance cracks at the crack inspection site basically disappear, meeting the standard requirement. The drilling and coring detection are carried out subsequently. The original cracks are fully filled and compacted. The appearance effect is good. The compression test of core also meets the design requirements, and the expected objective is achieved.
