5.5m捣固焦炉煤塔结构缺陷治理与研究

Treatment and study of the structural defects for the coal tower of 5. 5m stamp-charging battery

5.5m捣固焦炉煤塔结构在设计和施工中存在问题,导致深梁底部向外挑出的"牛腿"出现竖向裂缝、振动给料器产生共振、脚手架支承系统失稳等现象。分析问题产生的原因,并通过对"牛腿"裂缝修补、增加剪力墙、改进脚手架支承系统等方法对结构缺陷进行有效的治理。

Due to the problems in the coal tower structure of 5.5m stamp-charging battery in design and construction, it gives rise to abnormalities, such as vertical cracks at brackets overhanging from the deep beam,vibration feeders resonation and imbalanced bracing systems of scaffold, etc.. This pa- per analyzes the causes of the problems and gives solutions such as mending bracket＇ s crack, adding shear wall and improving the bracing systems of scaffold, etc. for treatment of the structural defects.
