Seamless connecting construction method for basement outer wall and fender piles

The invention discloses a seamless connecting construction method for a basement outer wall and fender piles. The method comprises the following steps: finishing construction of the fender piles; binding reinforcing mesh sheets on the inner-side soil body of a foundation pit; jetting cement slurry to form a wall surface by the inner side soil body of the foundation pit; performing drainage arrangement on the fender piles, and treating the pile bodies; performing water-proofing treatment on an enclosure system; arranging vertical steel bars, horizontal steel bars and stirrups on the basement outer wall; supporting a template on the inner side of the basement outer wall to form a single-side support system with the inner-side soil body of the foundation pit; casting concrete; removing the template when the design strength requirement of the basement outer wall is met. According to the construction method, the inner-side wall surface of the foundation pit is directly taken as one side template of the basement ou
