[0001] The invention relates to the technical field of building construction, in particular to a device and a method for preventing slurry leakage from the bottom of a concrete column mold. Background Art

[0002] With the continuous development of the construction industry, standardized construction has become a development trend. Whether it is residential or industrial plant, concrete structure is used as support. When pouring the frame column of the concrete support structure, it is necessary to build the steel structure through the formwork, and then pour concrete in the mold and wait for the column to be formed;

[0003] In the prior art, the frame columns of the concrete support structure are mainly fixed by clamping the mold with tension steel bars or external clamps during pouring to keep the mold stable. However, due to the complex environment of the construction site and the unevenness of the pouring ground, after the mold is built, the bottom of the mold leaks due to gap problems, which not only wastes materials but also causes "root rot" after the construction of the column. At this time, manual repairs are used, which wastes materials and manpower, increases construction costs, and seriously affects the construction progress. Summary of the invention
