The invention discloses a backflow prevention device. The backflow prevention device includes a stop valve; the stop valve includes a tubular valve body and a plurality of valve gates inserted on thepipe wall of the valve body; the upper and lower ends of the valve body are used to be tightly connected between a pipe column to be poured and a pouring material delivery pipe; when pouring, the valve gates are pulled out from the valve body, so that the pouring material in the pouring material conveying pipe is lifted into the pipe column through the valve body; and after the pouring is completed, and when the pouring material delivery pipe is disassembled, the valve gates are inserted and passed out of the valve body to prevent the pouring material in the pipe column from gushing down fromthe valve body. The backflow prevention device disclosed by the invention is simple to manufacture, can be used repeatedly, can effectively improve the jacking efficiency, and can reduce a large amount of manual rework.
本发明公开了一种防回流装置，包括：止流阀门，所述止流阀门包括一管状阀体，以及插接在所述阀体的管壁上的多个阀闸；所述阀体的上下两端用于密接在一待浇灌管柱与一浇灌材料输送管之间，其中进行浇灌时，将所述阀闸从所述阀体上拔出，使所述浇灌材料输送管中的浇灌材料通过所述阀体被顶升至所述管柱中，浇灌完成，拆卸所述浇灌材料输送管时，将所述阀闸插入并穿出所述阀体，防止所述管柱中的浇灌材料向下涌出所述阀体。本发明装置制作简单，可重复使用，能有效提高顶升效率，并能减少大量人工返工现象。
