Buttress column structure and construction technology thereof

The invention discloses a buttress structure and a construction process thereof, and relates to the technical field of buttress construction, the buttress structure comprises a reinforcement cage mounted in a basement, the top end of the reinforcement cage extends out of the top of an outer wall of the basement, and the reinforcement cage forms a buttress after concrete pouring; an embedded plate is welded in the reinforcement cage; the pre-embedded plate is composed of a pre-embedded steel plate and a plurality of pre-embedded steel bars, the pre-embedded steel bars are inserted into the reinforcement cage and welded to the reinforcement cage, the surface of the pre-embedded steel plate is parallel to the column face of the buttress column, and the side face, exposed out of the buttress column, of the pre-embedded steel plate is used for being fixed to horizontal steel bars of the outer wall of the basement. Through the arrangement of the pre-embedded plate, the basement exterior wall can be fixedly connecte
