Fair-faced concrete special-shaped wall pouring method
The invention discloses a fair-faced concrete special-shaped wall pouring method. The method comprises the steps that a formwork is installed, wherein the formwork is built according to the shape of a to-be-poured fair-faced concrete special-shaped wall; concrete pouring is conducted, wherein the to-be-poured fair-faced concrete special-shaped wall is divided into multiple sections from bottom to top, each section of the fair-faced concrete special-shaped wall is poured in multiple layers from bottom to top, the time difference of concrete pouring of every two adjacent layers is smaller than 5min, the tops of the two side walls of the lower section of the fair-faced concrete special-shaped wall are provided with inclined faces which are gradually inclined in the direction close to each other from bottom to top after the lower section of the fair-faced concrete special-shaped wall is poured, the upper section of the fair-faced concrete special-shaped wall is poured after the lower section of the fair-faced concrete special-shaped wall is solidified, initial vibration is conducted after each layer of concrete is poured, and re-vibration is conducted 20-30min after each section of the fair-faced concrete special-shaped wall is poured, wherein the re-vibration depth is 1500-2000mm; and formwork removal and maintenance are conducted, a mold is removed, and then the poured fair-faced concrete special-shaped wall is wrapped with a plastic film. According to the fair-faced concrete special-shaped wall pouring method, the problem that the appearance surfaces of the fair-faced concrete special-shaped wall are not consistent frequently can be effectively solved.
本发明公开了一种清水混凝土异形墙浇筑方法，包括步骤：模板安装，按照待浇筑的清水混凝土异形墙形状搭建模板；混凝土浇筑，将待浇筑的清水混凝土异形墙由下至上分为多段，每段清水混凝土异形墙由下至上分多层浇筑，相邻层的混凝土浇筑时间差小于5min，下段混凝土浇筑完后其两侧壁顶部具有由下至上逐渐向靠近对方的方向倾斜的倾斜面，待所述下段混凝土段凝固后再浇筑所述上段混凝土，每层混凝土浇筑完后进行初振，每段混凝土浇筑完后20min‑30min后进行复振，复振深度为1500mm‑2000mm；拆模养护，拆除模具，然后用塑料薄膜包裹对浇筑完的清水混凝土墙。该清水混凝土异形墙浇筑方法可以有效地解决清水混凝土异形墙时经常出现外观表面不一致的情况。
