Concrete construction method
The invention discloses a concrete construction method, and relates to the technical field of concrete construction. The concrete construction method comprises the following steps that a heat preservation formwork is installed, and a pouring area is formed; concrete A and concrete B are poured at the same time, the concrete A is poured on the edge of the pouring area, the concrete B is poured in the middle of the pouring area, and the concrete A is completely poured when the pouring height is 4/5-6/7 of the height of the pouring area; after pouring is completed, a protective shed is built for maintenance, and the temperature in the protective shed is 20 +/-3 DEG C until final setting is achieved; the protective shed is removed, the surface of the concrete is covered with a plastic film, the plastic film is covered with a straw mat, and natural curing is started. The concrete construction method is simple and easy to operate, complex heating equipment is not needed, the pouring process under a low-temperature condition is simplified, the problem of concrete cracks under the low-temperature condition is solved, and strength is improved.
本发明公开了一种混凝土施工方法，涉及混凝土施工技术领域。本发明的方法包括以下步骤：安装保温模板，形成浇筑区；同时浇筑混凝土A和混凝土B，混凝土A浇筑于浇筑区边部，混凝土B浇筑于浇筑区中间，浇筑高度至浇筑区高度的五分之四到七分之六处，改为全部浇筑混凝土A；浇筑完成后，搭建防护棚养护，防护棚内温度20±3℃，至终凝；拆除防护棚，在混凝土表面覆盖塑料薄膜，塑料薄膜上方覆盖草垫，开始自然养护。该方法简单易操作，不需要复杂的加热设备，简化低温条件下的浇筑过程，解决低温条件下的混凝土裂缝问题、提高强度。
