摘要
为了解决整体砌碹式支护煤仓施工工期长、砌碹模具加工工作量大等缺点,针对煤仓仓壁不同部位地质条件及受力状态差异,对煤仓仓壁的支护设计采用分段式支护。煤仓上、下锁口段采用砌碹式支护,中间仓体段采用锚网喷式支护。在满足煤仓使用要求的基础上加快了施工进度。
In order to solve the shortcomings of long construction period and large processing workload of the integral masonry type supporting coal bunker,according to the differences of geological conditions and stress state of different parts of the coal bunker wall,the segmented support is adopted for the coal bunker wall support design.The upper and lower lock section of the coal bunker adopts masonry support,and the middle section of the bunker adopts anchor net shotcrete support.On the basis of meeting the requirements of the coal bunker,the construction progress has been accelerated.
