Concrete pouring process
The invention provides a concrete pouring process. The concrete pouring process comprises the steps that first, a heat insulation shed is built, then steel bars are bound, a framework is mounted, concrete is poured, and finally, concrete maintenance is conducted, wherein during binding of the steel bars, heating wires and the steel bars are bound together, after concrete pouring is conducted for 1.5 to 2 hours, the heating wires are connected to conduct electrical heating on the concrete to prevent the concrete from freezing or cracking, after the concrete meets design strength, electrical heating starts to be stopped, and the cooling rate of the concrete is less than 5 DEG C/h when electrical heating is stopped. Concrete pouring in the concrete pouring process adopts a heat insulation shed pouring way, and the heat insulation shed should be higher no less than 0.5 meter than the top ends of the steel bars. The concrete pouring process adopts an electrical heating way to conduct heat insulation and maintenance on the concrete to prevent the concrete from freezing or cracking.
本发明提供了一种混凝土浇筑工艺，该工艺为：先搭建保温棚然后绑扎钢筋，再安装模板，随后浇筑混凝土，最后对混凝土养护；其中，绑扎钢筋时将加热丝和钢筋绑扎在一起，自浇筑混凝土1.5～2小时后接通加热丝对混凝土电加热，以防混凝土出现冻伤或开裂；混凝土达到设计强度后开始停止电加热，停止电加热时混凝土的冷却速率小于5℃/小时。本发明的混凝土浇筑采用保温棚浇筑方式，保温棚应高出钢筋顶端不少于0.5米。本发明采用电加热方式对混凝土进行保温养护，防止混凝土出现冻伤、开裂。
