The invention discloses a basement exterior wall post-cast strip advanced water stop structure which comprises an advanced water stop mold located on the outer side of a formwork of a basement exterior wall post-cast strip, and the advanced water stop mold is connected with a basement exterior wall and the formwork of the basement exterior wall post-cast strip. And the advanced water stop mold can block a gap between the basement outer wall and the basement outer wall post-cast strip. The invention further provides a construction method of the basement outer wall post-cast strip advanced water stop structure, the advanced water stop mold is installed, tension fracture of a coiled material waterproof layer caused by factors such as backfill settlement and structural shrinkage settlement is effectively avoided, the construction quality of underground waterproof engineering is fundamentally guaranteed, and the construction period is shortened. And the reliability of the advanced water stop structure of the basem
