Dam overflow surface one-time pouring construction method
The invention provides a one-time pouring construction method for a dam overflow surface. A dam or overflow dam section pouring area is divided into a distorted concrete area, a first roller compacted concrete area, a second roller compacted concrete area and an anti-impact wear-resistant concrete area according to the section from the upstream to the downstream; construction of a distorted concrete area, a first roller compacted concrete area and a second roller compacted concrete area is conducted, after second roller compacted concrete is constructed, the top of the right side end of the second roller compacted concrete is inclined downwards to form a surface hole overflow face step, and then one-time pouring construction of an anti-impact and wear-resistant concrete area is conducted; the construction process of the anti-scouring wear-resistant concrete area comprises the following steps: S1, foundation treatment; s2, binding reinforcing steel bars; s3, a formwork is installed; s4, concrete pouring; s5, the formwork is dismantled; s6, concrete plastering; and S7, concrete curing. According to the one-time pouring construction method for the dam overflow surface, the anti-impact and wear-resistant concrete is poured at a time after roller compacted concrete construction is completed, and the construction quality of the dam overflow surface is improved.
本发明提供了一种大坝溢流面一次性浇筑施工方法，将大坝或者溢流坝段浇筑区按上游至下游截面分为变态混凝土区、第一碾压混凝土区、第二碾压混凝土区、抗冲耐磨混凝土区；进行变态混凝土区、第一碾压混凝土区、第二碾压混凝土区的施工，第二碾压混凝土施工后其右侧端顶部倾斜向下形成表孔溢流面台阶，然后进行抗冲耐磨混凝土区的一次性浇筑施工，抗冲刷耐磨混凝土区的施工过程包括以下步骤：S1、基础处理；S2、钢筋绑扎；S3、模板安装；S4、混凝土浇筑；S5、模板拆除；S6、混凝土抹面；S7、混凝土养护。本发明的一种大坝溢流面一次性浇筑施工方法是在碾压混凝土施工完成后再一次性浇筑抗冲耐磨混凝土，提高了大坝溢流面的施工质量。
