Dam overflow surface concrete construction equipment and construction method
The invention discloses dam overflow surface concrete construction equipment and a construction method, the construction equipment comprises a trowelling tool, a dam overflow surface end plate matched with a concrete dam body overflow surface and a top die, and the top die comprises a plurality of square steels; the construction method comprises the steps that firstly, a supporting structure matched with the structural line of the overflow face of the concrete dam body of the current section is manufactured and installed; 2, the single-time pouring height is determined, and a plurality of pieces of square steel are installed from bottom to top according to the single-time pouring height; thirdly, single-time pouring and vibrating of concrete are conducted; fourthly, after initial setting of the concrete, the square steel to be dismantled is confirmed from bottom to top, then the adjusting short rods and the longitudinal supporting steel bars on the back face of the square steel at the position of the square steel to be dismantled are cut, and finally the square steel to be dismantled is dismantled; 5, plastering and calendaring the overflow surface; 6, finishing the construction of the overflow surface of the concrete dam body of the current section; and seventhly, construction is conducted to the bin collection elevation. The panel is made of square steel and can be suitable for construction of overflow surfaces with various curves and gradients, and the defect elimination procedure is not needed.
本发明公开了一种大坝溢流面混凝土施工设备及施工方法，该施工设备包括抹平工具、与混凝土坝体溢流面适配的大坝溢流面端板和顶模，顶模包括多个方钢；该施工方法包括步骤：一、制作与当前段的混凝土坝体溢流面的结构线适配的支撑结构并对其进行安装；二、确定单次浇筑高度并根据单次浇筑高度由下至上安装多个方钢；三、混凝土的单次浇筑及振捣；四、待混凝土初凝后，先由下至上确认待拆除的方钢，然后切割待拆除的方钢部位的调节短杆和方钢背面纵向支撑钢筋，最后对待拆除的方钢进行拆除；五、溢流面抹面压光；六、当前段的混凝土坝体溢流面施工完毕；七、施工至收仓高程。本发明面板采用方钢，可以适用于各种曲线和坡度的溢流面施工，无需消缺工序。
