摘要
结合太钢煤场改造工程施工实例 ,就桩底后压浆技术提高承载力的原理进行了介绍 ,阐述了其施工工艺流程及施工所需的设备材料 ,经载荷试验检测 ,单桩承载力提高 5 0 %以上。
Combined with the coal yard modification work according to the post grouting technology at the bottom section of columns its reinforcement principles are introduced as well as related construction process and required equipments and materials. Loading test shows the bearing capacity of single pile can be improve more than 50 %.
