Mass concrete pouring construction method
According to the mass concrete pouring construction method, before pouring, a control line is arranged above a pouring area, the control line is a continuous fold line, the starting point and the ending point of the whole control line are located on a pair of diagonal corners of the pouring area respectively, and the two ends of each fold line section are located on a pair of long edges of the pouring area respectively; the adjacent broken line sections are symmetrical about the width direction of the pouring area; and during pouring, two sets of pouring equipment are adopted to start continuous pouring at the same pouring speed at the same time. According to the method, pouring is carried out step by step with the paving area as small as possible, pouring is carried out to the designed elevation as fast as possible, the problems that the large-volume concrete supply strength is insufficient and too early condensation is caused by long-time exposure are solved, continuous pouring of the large-volume concrete is achieved, and the effect of effectively controlling construction cold joints is achieved.
本发明公开一种大体积混凝土浇筑施工方法，浇筑前，在其上方设置控制线，控制线为连续折线，其整体的起点和终点分别位于浇筑区域的一对斜对角上，其各折线段的两端分别位于浇筑区域的一对长边上，其相邻折线段均关于浇筑区域宽度方向对称；浇筑时，采用两套浇筑设备同时开始以相同的浇筑速度进行连续浇筑。本方法以尽可能小的摊铺面积循序渐进地进行浇筑、尽可能快地浇筑到设计标高，解决了大体积混凝土供应强度不足以及由于过长时间暴露导致过早凝结的问题，实现大体积混凝土的连续浇筑，达到有效控制施工冷缝产生的效果。
