2、建筑的结构特征

该工程主要由网架基础、堆取料机轨道基础和石灰石运输廊道组成，网架基础由40个钢筋混凝土基础组成的半径为56m的环形基础，基础之间用基础梁连接，供上部施工金属网架。堆取料机轨道基础是半径为51m的环型钢筋混凝土基础，基础底宽1.2m，高1.3m，设置8道混凝土后浇带以降低混凝土收缩应力，基础上部设计有预埋螺栓，用于堆取料机轨道的安装。石灰石运输廊道为本工程施工的重点，其主要部位是位于场内的箱体结构进料仓，外部结构尺寸；高11m，宽8m，长40.5m，壁厚1m，底标高-11m，局部-12m，因为是地下工程，施工时要考虑防水，防潮措施。

Structure Characteristic of the Construction

The Project consists of net frame foundation, stocking and reclaiming track foundation and limestone belt conveyor. The net frame foundation is made up of 40 reinforced concrete foundations. The foundations will be connected with beams. The foundation of stocking and reclaiming track is a round one of a semidiametre 51 m. The width of foundation is 1.2 m, length 1.3 m. 8 concrete rear casting belts are installed to reduce the contraction stress of the concrete.
