Device based on column bottom anti-seepage leveling and construction technology

The invention provides an anti-seepage leveling device based on a column bottom and a construction process. The anti-seepage leveling device comprises an anti-leakage leveling device which is integrally and fixedly mounted at the top of a lower foundation of a column foundation; an upper induction conjunction block is installed on the leakage-proof leveling device through a steel bar jig frame in a supporting mode, and a column foundation cast-in-place induction module is arranged in the upper induction conjunction block. A column bottom repairing module is fixedly mounted at the top of the upper sensing conjunction block, the whole column bottom repairing module is in a square box shape, the two ends of the column bottom repairing module are open, a fixing plate is reserved at the lower end of the column bottom repairing module, and an upper slurry screening layer, a middle slurry screening layer and a lower slurry screening layer are arranged in the column bottom repairing module; and the periphery of the b
