Synchronous pouring construction method for waterproof layer and main body structure of basement exterior wall

The invention discloses a synchronous pouring construction method for a waterproof layer and a main body structure of a basement exterior wall, which can be used for synchronously pouring the waterproof layer and the main body structure of the basement exterior wall by arranging a waterproof roll with grid ribs on one surface, a combined water stop screw and a screw hole waterproof repairing plug matched with the combined water stop screw for use. The problems that a waterproof roll construction base layer surface needs to be treated independently, waterproof lap joint is not tight, and the construction quality is not high are solved. The waterproof coiled material with the grid ribs on one side can be effectively separated from wall reinforcing steel bars, concrete holding and wrapping of the reinforcing steel bars are guaranteed, the waterproof layer and the formwork are clamped and fixed once through the combined type water stop screw, and after the formwork is removed, the waterproof repairing plug of the
