Abstract
The utility model discloses a prepared hole waterproof structure of a later-poured through-wall pipe. The prepared hole waterproof structure is characterized in that a groove is reserved in a concrete wall, and the length of the groove is 250mm. The length of the part, extending out of the concrete wall, of each concrete wall pre-embedded steel plate is 60mm. Fine concrete is filled in the groove, and the strength of the fine concrete is C30. A steel water stop ring is arranged in the part, in the middle of the concrete wall, of the through-wall pipe. The thickness of the steel water stop ring is 3-4mm. The external diameter of the steel water stop ring is 80mm larger than that of the through-wall pipe. A polyurethane waterproof coating film is arranged on the surface of the inner side of the concrete wall. The thickness of the polyurethane coating film is 20mm. Extruded sheet protective layers are arranged outside the polyurethane waterproof coating film.
