建筑物由于基础底板尺寸比较大,基础底板设有后浇带,后浇带将底板划分为若干部每一部分为一个自然施工段。整个底板面积较大,如总长为540m,由设计1m宽的横向后浇带以及4轴、8轴、12轴、16轴的变形缝隙将底板分54个施工段,最长长度40m左右,底板的厚度为1000、2000、3100不等。由于C30S8大体积混凝土有其特殊性,施工技术要求高,采用分段、分层浇筑。
Building due to the size of the base plate is larger, the base plate with post-pouring zone, after pouring the floor will be divided into several sections each part of a natural construction section. The entire floor area larger, such as the total length of 540m, designed by the width of 1m wide post-pouring and 4 axis, 8 axis, 12 axis, 16 axis deformation gap will be divided into 54 construction sections, the longest length of 40m, The thickness of 1000,2000,3100 range. As C30S8 bulk concrete has its own particularity, high construction technology, the use of segmented, layered pouring.
