The invention discloses a passive house wall bushing waterproof air tightness structure construction method, which comprises steps of: preservation of a wall bushing opening, mounting of a large bushing with an annular water stop ring, treatment of an interface of the preserved opening, mounting of a small bushing, foaming sealing filling of an annular region, mounting of the wall bushing, foaming sealing filling of a small annular region, waterproof and crack-proof treatment at the end part of the large bushing, water resistance of a first-layer insulation board and a structure wall body interface, mounting of the first-layer insulation board, staggered mounting of a second-layer insulation board, water resistance (horizontal) at the end part of the small bushing, water resistance (vertical) at the end part of the small bushing, water resistance of the wall bushing, construction of an insulation protection layer, and detection and verification of performance of the wall bushing. Measures of double-bushing protection, double-layer annular foaming sealing filling isolation, double-layer sealing treatment, double-layer staggered insulation energy conservation, four waterproof treatment and two crack-proof treatment are adopted, and integrated function requirements of passive building wall bushing protection, insulation energy conservation, air tightness and water resistance can be realized.
