Dam roller compacted concrete rollover construction method
The invention belongs to the technical field of dam construction, and particularly relates to a dam roller compacted concrete rollover construction method, which comprises the following steps of: paving a normal concrete cushion layer on a base for leveling with the thickness of 1.5-2.0 m; and the concrete is transported by an automobile and poured on the solidified normal concrete cushion layer, and then the concrete is paved and leveled in the direction parallel to the axis of the dam through a bulldozer. Formwork turning operation can be carried out on the formworks on the two sides of the dam at a time, the overall efficiency is high, the phenomenon that stress on the top face of the dam body is uneven due to formwork turning can be avoided as much as possible, the multiple formworks are designed in a split mode, large hoisting equipment does not need to be used, using limitation is small, and the stability of the formwork turning process is high; meanwhile, the multi-point compactness test in the roller compacted concrete can be carried out by utilizing the connecting point of the template and the pre-embedded frame, so that the laying quality of the roller compacted concrete can be improved, the template can be assisted to be separated from a dam, and the template turning action can be assisted.
本发明属于大坝建设技术领域，尤其是涉及大坝碾压混凝土翻模施工方法，包括如下步骤：在基底铺一层常态混凝土垫层进行找平，厚度为1.5m至2.0m；由汽车运输混凝土，并将混凝土倒在固化后的常态混凝土垫层上，然后通过推土机沿平行大坝轴线方向摊铺找平。本发明可以一次性对大坝两侧的模板进行翻模操作，整体效率高，并可以尽量避免翻模导致坝体顶面受力不均的现象，且多个模板的分体设计，无需使用大型吊运设备，使用受限小，翻模过程的稳定性高，同时可以利用模板与预埋架的连接点进行碾压混凝土内部的多点密实度测试，利于提高碾压混凝土铺设质量，且可以辅助模板脱离大坝，并辅助进行翻模动作。
