在浅圆仓地面组装钢桁架,利用仓壁顶的20个电动葫芦同步提升钢桁架到预定高度安装就位。然后进行穹顶模板安装及浇筑混凝土施工,穹顶结构施工荷载通过桁架及牛腿均布分散传递到仓壁至地基。穹顶在牛腿对应的位置留置20个预留孔,在预留孔处布置20个电动葫芦架。利用电动葫芦将拆除后的模板材料随钢桁架同步落地运走。
Assemble the steel truss on the shallow silo ground and use the 20 electric hoists on the silo wall top to synchronously lift the steel truss to a predetermined height and install it in place. Then the vault template installation and pouring concrete construction, the construction load of the dome structure through the truss and corbels evenly distributed to the warehouse wall to the foundation. Dome in the corresponding position of the carp placed in reserve hole 20, in the reserved holes arranged 20 electric hoist frame. Use the electric hoist will be removed after the template material with the steel truss floor landing simultaneously.
