The invention discloses a ground ceramic tile paving method capable of preventing bulges. A special mortarboard, a ceramic tile mortar coating machine and a seam partition/flattening device are used; notches are uniformly formed in one long side edge of the special mortarboard, and a strip-shaped mortar layer with the consistent thickness can be paved on the ground; the back surfaces of ground ceramic tiles of different specifications can be coated with a strip-shaped mortar layer with the consistent thickness through the ceramic tile mortar coating machine, gaps with the uniform and consistent width can be spaced between the ground ceramic tiles by the seam partition/flattening device through vertical plates of T-shaped plastic partition plates, and the levelness on the ceramic tiles can be consistent through plastic wedges; and the construction steps of the ground ceramic tile paving method comprise coating of the ground strip-shaped mortar coating layer, coating of the strip-shaped mortar coating layer of the back surfaces of the ground ceramic tiles, paving of the benchmark ceramic tiles according to the mode that the strip-shaped mortar layers are perpendicularly staggered, paving of the other ceramic tiles according to the mode that the strip-shaped mortar layers are perpendicularly staggered, clearing of the vertical plates of the T-shaped plastic partition plates and filling of the gaps. According to the ground ceramic tile paving method capable of preventing the bulges, the bulging phenomenon is avoided, meanwhile the hollowing phenomenon is avoided, and construction efficiency is high.
