[0042] The grouting plugging device provided by the embodiment comprises a plurality of plugging plates 1 and corner connecting pieces 2. The plugging plates 1 are detachably connected, which facilitates the transportation of the grouting plugging device. The number of the plugging plates 1 can be set according to the size of the prefabricated column 100, which has high applicability. After the construction is completed, the grouting plugging device can be recycled, which is green construction and reduces the construction cost. The two plugging plates 1 are connected through the corner connecting piece 2, so that the plurality of plugging plates 1 are arranged on the circumferential side of the prefabricated column 100 through the corner connecting piece 2 and block the gap to perform grouting.
