Concrete pouring method capable of adjusting delayed coagulation time
The invention relates to a concrete pouring method capable of adjusting delayed coagulation time. The method comprises the steps that vertical rods of a scaffold are arranged on cross beam ground projection axis cross points at first; cross beam steel bars are bound based on a design drawing, and the direction of the cross beam steel bars are perpendicular to a long shaft and a short shaft of an oval floor system; then, machined cross beam side form boxes are placed in the cross beam steel bars and are reinforced; concrete is configured, wherein a retarder is mixed into concrete, the weight ratio of the concrete to the retarder is 200-100:1, and an appropriate amount of tap water is added into the concrete and the retarder which are evenly mixed according to a certain proportion for even mixing; finally, concrete is poured, wherein the concrete is poured in the cross beam steel bars layer by layer. Due to the fact that the retarder is mixed into the concrete for pouring, the solidification time of poured concrete is prolonged, and construction gaps are prevented from being generated between concrete layers after grouting.
