随着国家煤炭产业政策的调整,煤炭原煤的洗选率进一步提高,越来越多的选煤厂面临扩容改造、产业升级的局面。然而选煤厂主厂房大多数服役年限已长,破坏严重,且设备较多,改造范围大,因此,改造加固的重要性日益凸显。本文重点分析了主厂房混凝土结构的加固设计,同时指出了设计人员易忽略的几个方面,并给出了相应的处理方法。 With the adjustment of national coal industry policies, the washing rate of coal raw coal further improves, and more and more coal preparation plants are facing the situation of capacity expansion and upgrading and industrial upgrading. However, most of the plant life of coal preparation plant has been long service life, serious damage, and more equipment, a large range of transformation, therefore, the importance of rebuilding and reinforcement has become increasingly prominent. This article focuses on the reinforcement design of the concrete structure of the main plant, at the same time points out several aspects that designers can easily ignore, and gives the corresponding treatment methods.
